CSC segment and LCT efficiencies. Stephen and Isa

ME-1/3/(8, 15, 22, 25) low WCT efficiency
Chad investigated.  CLCT issues
 - CLCT0 low quality (What does this mean?)
 - CLCT large fraction of completely missing CLCT data
 - ALCT small fraction of missing data, probably caused by missing CLCT data
 - Low rates of CLCT pre triggers across all CFEBs
 - Often 50% occupancy compared to other chambers
 - ALCT rates generally look okay
Actions
 - Find out what some of the above metrics mean
 - Continue to investigate with Chad
 - Present the problem with evidence to CFEB expert (who?)

ME-2/1/17 low segment efficiencies
 - Chambers timed differently by about 0.1-0.2x(time bin)
 - we think this is likely to cause problems since relative mis timing between strip data and wire data could cause a reconstruction inefficiency
 - “even” vs “odd” time BX might show the problem differently but we don’t know if we have this information
 - Problem is likely in offline calibration but the offline calibration is dependent on the online calibration
Actions
 - Present problem with evidence to Misha, expert on online timing calibration, back from vacation tomorrow (third highest priority)
 - With Misha Determine whether problem is purely offline or also seen online. 
 - Ask about availability of information “even” vs “odd” BX relative to the time bin

ME1/1 an other ring or ring back vs. front efficiency issues
 - We doubt that this is an eta cut dependent issue
 - We would like to understand if the sonly happens in ME11a or also elsewhere
Actions
 - Plot efficiency for back vs. front chambers in: (Armando should confirm this list) (highest priority)
   - ME11a (done)
   - ME11b
   - ME21
   - ME31
   - ME13
- Plot efficiency with wider cuts on sigma and fixed windows.  8sigma and 8cm
- Look at some event displays to determine what is happening (suggestion from Tim)

General efficiency plots
- We need to finish 2018a and move onto a second period
- We would like to pursue a general project of making the code run faster
Actions in order of priority
- Finish 2018a plots (second highest priority)
- Investigate improvements that can be made in 2-3 days
  - Configuration variable to control which project is produced
  - Investigate altering the code to produce all projections at once.   Do if feasible in a few days
  - Determine the minimum about of data necessary to produce plots when performing “test” or “debugging” runs.  Is this faster?
  - Investigate overall code to make sure the loop structure makes sense
- Start running over 2018b or other period


CSC current data vs instantaneous luminosity.  Jithin
- Purpose is to detect issues like the onset of matter currents
- Discussed that comparisons of + vs - chambers in the same position is the cleanest comparison
Actions
- Continue investigation of chambers
- Investigate whether code or ideas from neutron background studies is useful

CSC neutron background studies
- received code and documentation from UCLA group
- Need to discuss and determine best project
- Ideas:
 - Continue work on simulation and comparison of P5 vs GIF data.   Understand why we see substantially different current per hit
 - Run more modern P5 data to get a larger sample at high instantaneous luminosity
Actions
- Study code and run
- Determine best project goal

   - Make vs. eta and pT plots and circulate to team
   - Make vs. primary vertices plots if possible
   - Add "2018A" to plots
   - Add caption statement on what chambers are removed
   - Suggested statement: Efficiencies vs phi, eta, pT and the number of reconstructed primary vertices only include chambers without known readout problems.  XXX of YYY chambers included
   - Create presentation indicating that plots are for approval and suggested statement on chambers included
Progress on 2018C running
  - Expect jobs to finish in one day
  - Check if running multiple projections is possible by existing switch or simple change to the code.
2017F data
   - Start 2017F jobs
   - Need to find permanent storage location for ntuples.   
Progress on getting failed event list and failed events
   - Check if run and event numbers are available in the ntuple
   - If so, develop list of cases where segment is lost in ME11
Query on whether Zmu skims made for 2017
   - Need to ask whether this was done
Response from Misha on timing in ME2/1/17...
  - doesn't think that this would effect efficiency
  - need to ask offline expert (Chang?) how this propagates to the offline code
  - check offline after fix is done
  - check new data when it comes in


Jithin
Status of new channels with Malter current
  - Shown in this presentation.:  Easy to see evidence of Malter current based on current data
  - Two types of Mater current.  Beginning of fill and end of fill
  - First starts soon after beams start colliding and decines with time
  - Similar problem seen in end of fills
Status of ME4/2/10 ratio comparisons
  - Ratio comparisons of chambers in different locations.   Difficult to see any pattern when comparing chambers
  - No clear effect seen tine top CSC chamber
  - Should undestand what a typical increase in current is given the problem.
  - Need a way to store current data in a database

He
Progress on getting neutron background code to run
  - He working on understanding CMS infrastructure and tools used in the analysis
  - will focus on charge to hit ratio for neutron events as the primary goal of the project
  - new samples for neutron backgrounds being produced.  Can try running them first if they are ready in a timely manor.

2017 08 15

  • CSC HV current studies
  • Studying current in top chambers that have larger occupancy
  • Possibly neutron backgrounds
  • Expect a 50% effect
  • Can't see clear effect from simple current plots or ratios to chambers with lower occupancy
  • Difficult because of poor granularity of the data
  • Ideas
  • Armando: Form "double ratios" of means to between other voltage segments a chamber and other chambers
  • Matt: be sure to eliminate unstable data at the beginning and end of fills and perhaps other outliers
  • Matt: Use current vs luminosity fits which stabilize the results. Probably would still want the double ratio

  • CSC LCT and segment efficiencies
  • LCT efficiencies resolved
  • Several chambers has wrong CFEB timing parameters
  • Others may have cable connection problems which needs to be checked

CSC team meeting August 20th 2018

CSC segment and LCT efficiencies: Stephen
Progress on 2018A official plots
- Thanks for sending the updated plots.  They generate several
questions and comments.  Also, as Armando pointed out, probably we do
not want to show them publicly while issues like the possible ME1 segment builder problem are resolved.
- Questions and comments
- Page 7: When we remove "chambers" are we removing chambers or chamber regions?   Please tell us what is the denominator for the
number 51.   Also the number is quit high.  Order 10% of the system. For Armando: How do we want to present this information?
- Page 7 lower: Also in this plot what is the denominator.  i.e. the number of ME1 chambers.
- Page 9: The pattern of inefficiency is quite interesting.  Is it possible to make these plots subdivided between even and odd chambers?  Are there enough statistics to divide eta more finely.  If possible I would like to shrink the bin size by something like a factor of 2 to 4.
- Page 9: bin edges for ME1/1b (ends) and ME1/1a (starts) should be at 2.1.  A bin that overlaps that region might be artificially low
- Page 11:The ME11A plot end at ~100GeV.  This is likely a statistics problem driven by p being largely pZ at higher eta.  For Armando.  The patten of pT in these plots may represent a failure of the RU algorithm at low pT.  For instance the raise in efficiency at low pT for the high z stages that is not present in ME1.
- What are the prospects for the vs number of PV plots?

- We think RU (road usage) algorithm is improved wrt the ST (spanning tree) also.  Therefore, there is likely some implementation problem.


Progress on 2018C running

Progress on getting failed event list and failed events
 - This is lower priority now that the segment builder problem is being investigated.

Query on whether Zmu skims made for 2017
 - Please increase the priority of inquiring whether these are or ever can be made available.

Response from Misha chamber with a timing issue
 - Misha said that this is likely not a timing issue and needs further investigation.  Did he have suggestions for what investigation should be done?
 - We had wanted to understand how a mistiming at the trigger level effect offline timing.  Is there something we can do to pursue this.


Jithin
Status of ME4/2/10 ratio comparisons
 - Fits: For cases where all the data is good the chi2 criteria may eliminate good
   points.  You can just ddd little to the right side of the
   expression, for instance +2.0, which should take care of the problem.
 - Means: The mean should depend on the sampling of points with luminosity.
   Could we see some examples of how the mean looks like on the fit
   plots.  Hopefully the mean corresponds the value of the line
   in the center of the plot.
 - The differences in means for the ME4/2 chambers look pretty
 significant.   It may not be necessary to be exact in how the
 averages are calculated to see these differences.
 - For the chambers ME4/2  1 vs 9 and 10, can we see the fit plots, and are the slopes different? 
 - Armando suggests selecting periods where the luminosity is stable
 - Armando would like to see the results from more wedge in phi to confirm the pattern.

He
Progress on getting neutron background code to run.
 - Both learning out issues like python control scripts and trying to

CSC team meeting September 13th 2018

CSC segment and LCT efficiencies: Stephen
Extracted ME1/1 events released - 100 events released for Event Display work
  - Will point RU authors at full set of failed events.
  - TnP appears to work fine now, will run on 2018A again to check for any differences and compare runtime.
  - Have not assessed improvement in run time yet
  - Will produce full set of plots including PVs by next week
  


Current measurement: Jithin
Now have current vs luminosity measurement using Katarina's and Igor's data.
There are differences in outlier removal methods and collection methods.
Igor - Luminosity from closest measurement, measurement every 1.5 sec
     - Direct removal or outlier luminosity measurements
Katerina - Luminosity from average over time period where current measurement was constant
         - Outlier removal by chi2 criteria
Matt will make proposal on outlier removal.  The we should make some comparisons using chi2 to a-priori determine which measurement is better.



Neutron background studies: He
Progress on getting code to run.  Thinks he may have surmounted problems with getting data structures to fill. 



 Isa
T&P efficiencies using 2018D and comparing 2018A and 2018D
Will investigate chambers "known" whiteboard problems that are minor
enough that the efficiencies are good.   We should suggest, if
appropriate, removing chambers from the whiteboard or re-classifying 
them as with issues but good as in terms of efficiency.

What about lower LCT efficiency in ME1/1?  Tested in ME1/1/11 and saw no effect.  
Will check if we just require a LCT segment or if we explicitly check that the LCT segment 
has 4 hits.  Check how we access the LCT segment from the trigger path. 

Other Upcoming work
  - rerun Stephen’s failed events with ST algorithm
  - investigate front-back asymmetry
  - Make projections for 2018D


Will separately discuss with Kevin and Armando the CSC backend readout card projects.

  • CSC failed events
  • Used event display to look at failed events

2018 09 14

  • CSC current measurement
  • Proposed method of outlier removal


Improving our methodology.   
1) Within should investigate Igor’s method for outlier removal.   If it seems well designed we could 
apply it to Katarina’s dataset as a first step of processing to make the two dataset more equivalent.

2) We should change the chi2 selection method to iterate the procedure.  Right now we establish a 
fit and test chi2 against it using data that includes the outliers which could adversely impact the fit.  
I would suggest that we iterate the procedure three times.   The first and second steps would use a 
very loose chi2 cuts to remove data the are extreme outliers.   I would suggest using 5 times our 
current cut and then 2.5 times our current cut before proceeding to our final selection.  After each 
step of removal, re-perform the fit to get a better result.


Determining which dataset is better.   
Once we have what we think is a good fit then I think we can determine which dataset is better by 
comparing the average deviation of the points from the fit.   I’m not sure how we are forming the chi2 
since the uncertainty of the fit points is not well defined.   That may be an adequate standin for average 
deviation as long as we think it is equivalent between the two cases.

  • CSC LV distribution board status
  • Discussed with Dick
All the materials necessary to bid the construction of the LV junction box components are now ready 
and we expect the bids to go out sometime soon.   Dick informed me that PSL has a new automatic 
machining station that they could use to do the project themselves.   Likely they will bid as well and 
as long as their bid is in line with the external bids we could accept their bid for the project.   Tentatively 
the schedule would be the following:  

1 month for bids
2 weeks to order and obtain materials (Dick said this should be quick since we are not ordering anything unusual)
1 month until the parts are available to construct a first prototype.  Probably a 2 cell box.

That would set the beginning of December as a likely date to have a prototype.

I think we should schedule Stephen to come out at the beginning of December.   
The stay might have to be slightly longer than otherwise necessary because of 
the Christmas holiday.  Perhaps Stephen could stay till mid or the end of January.   
That would also allow for slip in the schedule.

CSC team meeting September 21st 2018

CSC segment and LCT efficiencies: Stephen
- Failed job issue solved
- vs. PV plots done
  number of interactions now consistently goes to 60 so we should
  extend the range
- plots discussed to Tao Huang and sent to monitoring group

Current measurement: Jithin
- Current measurements using Katarina's and Igors data shown
- Plots with high, low (at low current) and  highly fluctuating statistics shown.
- High statistics plots seem to indicate that in Katarina's method she may
  be removing points from the bulk of the distribution, especially at high lumi.
  This could substantially change the average.
  Jithin will discuss with Katarina
- Low statistics and low current plots indicate that the iteration of the
  chi2 selection seems to work in stabilizing the result from lower
  statistics and lower current plots.   
- Some plots (from Igor) have highly fluctuating current of lumi values.
  Jithin will discuss with Igor
- Also the plots of the chamber segments with deviation from linear
  behavior were shown 
  Isa suggested looking at that segment in other chambers and/or chamber types


Neutron background studies: He
- Progress on getting code to run.
- Seems to be a technical problem with getting the analysis stage of the jobs
  to run
- He consulting with authors and other UW people
- UCLA people suspect a change in the products that are available
- Tried to run MC samples which had the same issue


 Isa
- Updated whiteboard with new problems and will follow up on them soon
- Ran 2018D data to higher statstics confirming improvements due to OTMB firmware
- Showed high vs. low luminosity plots which confirmed Stephen vs PV results but
  now at the chamber level.
  We would like to make a difference plot and Stephen has some code to do this
- Sent to Tao Huang and monitoring group
- Tried to run ST it did not seem to work correctly.
  Nikolay has run and found the segments.
- Good progress on setting up for LS2 DCFEB work
  Working on setting up a pilot DCFEB refurbishment test

Outstanding problems
- Is 3 hit vs 4 hit issue in ME1/1/ being treated correctly.  
- investigate front-back asymmetry
- Make projections for 2018D

Follow up email
Outstanding questions from the meeting.

For Armando
- The new OTMB firmware seems to really make a difference.   
  What is the schedule for rolling this out for the whole CSC system.  
  What additional tests have to be done for the CSC group to feel comfortable doing that?
- Do you have any insight on the deviation from linear behavior Jithin sees in ME2/1 segment 2.  
  Isa suggested looking at some other chambers in the same and different rings.

For Isa
- What’s the status on whether we are treating 3 vs 4 hit correcting when measurement the LCT efficiency?   
  I’m not sure whether what you reported says anything about that issue.

CSC segment and LCT efficiencies: Stephen
doc shift this week

Working on eff v lumi comparisons using Isa's 2D plots.
These plots will directly compare high vs low lumi

2018 efficiencies.
2018A previously done with projections, but should be updated
2018D efficiencies done but not projects.

First we want to address binning issues for projections
Eta binning to correspond to detector boundaries was done.
PV to be done but should be quick.
Produce 2018D projections once binning issues are delt with.

Need to address issue or removal of probes for all chambers when one chamber is bad.
Also address good chambers that have minor problems.

 

Current measurements: Jithin
Did some study of current in ME 4/2/10 (plus and minus) for Fills before and after TS2.
New shielding was installed.
Misha did online hit rate study
Nick? is doing offline segment occupancy study
Jithin is doing current study
Preliminarily the external segments, 1 and 5 look good.
Completed results for all studies to be shown next week on Wednesday


ME1/1 current response is a feature of the CAEN system which is noisy.
There is a section the neutron background on charge to hit ratios on these issues.  We should read pages  31-45.
These issues effect what we would estimate as the systematic uncertainty and detection of malter currents.   

 

Neutron background studies: He
Code now runs on test MC sample
Will request analysis scripts from UCLA group
Will keep Tim, Indara and MC people in the loop on the progress on the MC samples
Will ask for configuration information for MC sample.  This should allow us to set the correct global tag

Isa
On CLCT firmware change.
New CLCTs are found in the trigger and found by the tag a probe but not linked to trigger tracks.  
Timing may be an issue because the tag and probe does not check that.
Isa, Chad, Tao should collaborate and try to make a report by next Wednesday so that we can get feedback from the CSC community.
Also suggested to try a trigger emulator to analyze the problem if it would be useful.  Maybe Tim would have more suggestions.

CSC segment and LCT efficiencies: Stephen

Status of (with Isa)
Running new data period post HV changes using latest JSON information.
Expect results within ~one day.

Status of
re-binned eta plots with the treatment of edge eta bins.
Will send new plots around when ready.  

Status of
two lumi comparisons
Showed different in efficiency for low vs high luminosity per ring.
The statistical uncertainty is large enough to obscure the meaning of these plots.
Armando suggested showing the average efficiency (y) vs chamber number
(x) for the high and 
low luminosity data on one plots.  A straight line fit could used to determine the two averages.
Matt suggested using well separated low and high luminosity regions.
The regions should be 
a separated as possible while being large enough to get good statistical power.


Status of
probe removal issue.
Difficult but not as bad as Stephen thought.
It seems possible to calculate the only removing entries in a given ring
The tag and probe job runs separate sub jobs per ring so it should be possible to remove
probes per ring.  
May introduce artificial inefficiency in chambers shadowed by a bad
chamber because the efficiency for reconstructing a muon will not be
as good.  However, this is better than not calculating the efficiency
in the chambers shadowed by the bad chambers.





Current measurements: Jithin

CSC segment and LCT efficiencies: Stephen

Status of
Comparison of efficiency before and after HV change data
Use 1D histogram.  Separate out rings and indicate in slides rings where voltage was changed and by how much.
Calculate the mean and uncertainty on the main with removal of
outliers beyond 10% directly using the efficiency data directly.  
Limit plot range to +-10%


Status of
Running new data.
Finish testing the performance of the probe removal code before moving to new data again 
Then produce a complete set of new plots for the new data
After than decide which dataset is the next priority

Status of
re-binned eta plots with the treatment of edge eta bins.
Done looks good.
Eventually we should consider converting plot to detector eta so that bin
edges will more exactly follow the detector geometry.

Status of
two lumi comparisons.
Lower priority.  Still need input from Isa.
Previously decided to consider a high and a low luminosity range with a
considerable seperation between them.




Current measurements: Jithin
Status of
Current measurement plot before and after TS change to shielding
Plots using the 2 runs processed match our expectations and show about
a 15% effect .  However, we don't understand the 
correct uncertainties for these plots.
Producing extra runs before and after
Producing extra unaffected chambers comparisons before and after



Neutron background studies: He
Running code takes three steps
Discussing with Indara/Tim and maybe Slava how to run CSCValidation as
a quick check
Code Indara pointed us to looks good.


Isa (on vacation)
Status of
New firmware - determine whether this task is now complete

Status of
RU reconstruction

Status of
Front back asymmetry problem
Need to revisit how to progress on this issue.
Does the probe removal or new RU hit and segment reconstruction help?

These projects should be assigned to other people given Isa's new duties as
deputy CSC upgrade coordinator.


Other issues

Asked Kenneth to make data certification instructions.  Kenneth says he
will work on this.

Looking at how to run relvals on MC files as another way to
look at MC data for things like Neutron background sample


Will pay weekly site visits to PSL to monitor progress on LV boxes.
Dick updated me on the status.
Micarta pieces are ready
Bent copper pieces in process, should check on progress
Other parts on order
Have decided not to bit machining and have PSL do it, not price yet but will be more
Need to understand machining schedule
Could construct a box once all parts for one of the three types is ready
Many parts in common and each part would probably be run at once.

Chamber installation fixture 

There is a DUNE Collaboration meeting during the last week of January.   Dan could possibly add time before or after the dates of that meeting. After that meeting there is a design review in the United States that he has to attend so if he needed to schedule a separate trip to CERN it would have to wait until later in February.  He would like to understand what the first day it might be possible to have access.  If there is no access he could at least check out the fixture and discuss it operation that week.  If there is access and it's possible to remove chambers he could re-demonstrate help with the removal of the problematic chambers like those under the nose.


LV junction box status.

All parts needed at PSL have arrived.
This includes micarta, din rails, copper pieces, screws, lugs and other miscellaneous parts.

The Micarta pieces are being  machined using water jet cutting and the last ones are probably being finished today (Friday) or Monday.  The shop Manager, Tom Harrington,  is visiting the vender daily to help out and monitor progress.

The next step is inserting lugs.   PSL has arranged to split performing this job with the waterjet machining vendor which will cut the time considerably, though not quite in half.  They are designing a priority list for this part of the job so that the parts for one type of box will be prioritized and ready for assembly as early as possible.

All cooper pieces have arrive and most of the bus bars that have to be bent have undergone that process.    There is still some work to do to thread various holes.  They told me that the bending process has been easier than the last time since they were able to obtain a substantially soft copper.   Otherwise the properties, such as electrical properties, should be the same.  I asked if this ment the holes might be more easily striped.   They don't think it will be a concern but they will test one to see how much torque can be applied without causing problems.

They expect to have everything ready to put together an initial box early to mid the week of Nov 20th, Thanksgiving week.  Unfortunately that might not be a good time to test the process of putting a box together because of vacations, but if they are ready early then they will test the assembly process and I will attend.  Otherwise they would perform this test this on Nov 27th - again I will attend.


Things should move quickly then and then and they will target Midweek of the week of Nov 27th to ship the materials.   Door to door, air option, which is not that much more expensive than ground, would take one week.  That is not counting any time to get through CERN shipping and receiving.  Dick warned me that we should interveen to expedite the shipment through CERN shipping and receiving.

Note that after writting up this notes I double checked all the dates and some of the more important details with Dan to make sure that I hadn't misunderstood or misremembered and also that there was not any substantial risk that the timeline would stretch beyond the dates that were discussed.  


One question that came up was on the packaging of the materials.
For each box type they will make a spreadsheet that indicates the parts numbers of the all the parts that are used for assembly and highlight the relavant number on the box of parts.  Parts like the micarta, bus bars, din rails and other miscellaneous parts that are not things like screws will be packaged into kits for each box.  Then there were a few options.  1) Leave all the small parts together in their current packaging, 2) repackage them dividing them into sets by box type, repackage them to the level of individual box kits along with some spares.  The last seems easiest from our point of view, but I would be concerned that it is also the option that makes it most likely to lose some critical part.  I would probably favor one of the first two options.  However, you should give your opinion.

CSC segment and LCT efficiencies: Stephen

Status of
Fine eta plots.
 - Need more specific run ranges for before after comparisons
 - Stephen will send out fine eta comparison for whole data periods.

Folded phi plots should be possible.

Priorities going forward
  ST v RU comparisons
  High/low lumi comparisons
  Chamber exclusion shadowing study
  Internal phi efficiencies (“folded” plots)


Current measurements: Jithin
Don't understand the pattern of current in the rings and chambers.
Especially don't understand the 1/2 2/2 3/2 plots.   Will try other phi
locations and rings.   May try to include 1/3 but the data is not very good.

 

Neutron background studies: He
First plots shown and patterns seem to be as expected.
 - Segments show most additional segments in stage 1 closest to the interaction region.  This is probably shorter time scale collision related backgrounds
 - Hits show very large contribution in stage and a second set of contributions that is large in stage 4 and decreasing as you go inward.  This is probably longer time scale neutron gas related backgrounds.

Next steps
 - renormalize plots by number of events in each sample.   The y axis will be number of hits or segments per event in each bin.  However, keep the current normalization to equal area also.
 - Rescale y axis to so that all bin content in on scale
 - label plots and axis's more carefully
 - Run new samples from MC group and compare

 


Isa
- organizing tests for Tomsk technicians, both technicians trained as of next Tuesday
- prepared LHCC slides for UCO meeting
- attended session about new transport rules
- Some DCFEB soldering and tests delayed due to transportation issues but should be done by Monday.  Maybe we could do it in the RP buffer zone a P5.
- Trying to determine a process that will not result in delays during the full refurbishment process.   Also we could also extract a chamber early to test and see if transportation

  • PSL visit for LV junction boxes
  • Assembled box and assed status

In general the LV box assembly went very smoothly.   All of the machining  micarta and metal parts has been done very precisely and everything fits together very smoothly and tightly.   The assembly is fairly straightforward after you have done it once.   As well as the instructions we will ship one fully assembled box which should make it fairly obvious how to put them together.    Also for some of the screws specialized tooling helps with the assembly.   The tools, including a spare set, will be shipped with the box parts.  One thing to note is that definitely the assembly is a two person job.   Otherwise, I don’t anticipate problems assembling the boxes at CERN.

 One problem we found was that one set of holes and inset lugs was not done by the vender working on the micarta pieces.   It involves machining two holes and insetting lugs on about a dozen micarta pieces.   PSL has the tooling necessary to do that.   It’s just a few hours of work and PSL does not anticipate any delay in shipping.  They are still targeting shipping by the end of the week.

 When they ship they will notify me and provide all the shipping information.

CSC UW Meeting Nov 30th 2018

Stephen CSC efficiency studies:

RU vs. ST jobs in progress
  - test jobs likely to finish tonight
  - longer jobs over the weekend
  - testing standard RU vs ST to see if we see efficiency loss
  - will move on the new RU algorithm next
  - matt suggests downloading and testing new RU algorithm
    immediately in order to address any technical issues sooner.


2018D data
  - fine grained eta plots were shown with 2018a 2018d comparison
  - would like to see PV plot with 2018a vs 2018d comparison
  - if they show the same result then the efficiency differences are
    driven by instantaneous luminosity

He neutron background studies
  - Improved neutron background with no improved cavern and shielding description vs
    old neutron background with improved cavern and shielding description shown
  - Other files were not readable.  Have asked MC experts about this issue
  - Ring plot when to ring 4 which needs to be understood.

Isa:
  - Gamma spectroscopy of DCFEB boards down.  Boards will likely be classified
    as radioactive.  However, level may be low enough for self transport.
    New boards will have to be tested when we get access

Jithin
  - Stores from 2017 vs 2018 compared
  - phi location in 18 chamber rings vs. 36 chamber rings mean some comparisons are not
    at the same phi location
  - Would like to see comparison for two very close stable runs, highest priority
  - Would like to see time history of slopes. Perhaps ~12 points over the course of a year.
  - Jithin says this may not be too difficult

* CSC current meeting summary, conclusions and questions * Armando, Matt, Jithin, Igor, Katerina in attendance



1) We probably prefer Igor’s method of extracting the data because it is much faster.

2) Using Igor’s data as input we prefer to use method we have developed for extracting the I vs L slope.  That includes our method for eliminating the tails at the beginning and the end of the fills and our outlier removal method.
Questions:    Are we using the iterative outlier removal?
         Do we want to investigate further Katerina’s method of luminosity averaging?

3) We want to extract I vs L slopes per fill, per high voltage segment, and corrected for area.  Then we would characterize the chamber current as a single number based on the slope with appropriate units.

4) From this we would extract a stable data set for study based on a criteria like chi2.   Though we would a monitor the unstable set.
Questions:    Our outlier removal may remove cases where there are matter currents.  Jithin, have you looked at chambers with Malter currents.  What sort of results did you get?   Do we want to allow this to happen or do we prefer to design our stability criteria to specifically remove Malter cases.
         Some stages or rings are different, typically due to the lower current compared to the granularity of the readout or different current readout systems.            Do we want to have several different stability criteria?

5) We want to investigate averaging.  The most obvious case is to average over phi.
Question:    If we do that, do we want to remove specific chambers where we know there is an issue with backgrounds.

6) Question: Do we want to correct for things like pressure.   In Katerina’s slides it removes the slope with time, but in seems to cause more problems by causing  some points to be substantially far from the bulk of the data.

7) For plotting, when not averaging in phi or plotting time dependent properties, we would like to move plot that displays the system as circles, one for each stage.   The circles  would have several rings and maybe would make it possible to further break down to the level of voltage segments.   The plots could compare to a reference run.  We would also like to do this for efficiencies.
