LBCF Shift_FAQ

Silly shifter questions & regulations

Before shifts: what to do ?

Before the shifts start:

  1. check your access rights to ATL_CR (Atlas Control Room)
  2. look througt the most recent LBCF, LUCID, ZDC, BCM instructrions:
    http://pcatdwww.cern.ch/twiki/bin/view/Main/BeamConditionsOperationManualShifter
    http://pcatdwww.cern.ch/twiki/bin/view/Main/LUCIDOperationManualShifter
    https://twiki.cern.ch/twiki/bin/view/Atlas/ZDCShifter

If need to contact the LBCF shifts coordinator in a harry, look for the phone here.

Atlas Control Room (ACR): How to find it?

  1. Building Location
  2. Web cams

IMPORTANT: try to speak in a low voice !

Please try to speak in a low voice with your desk(s)-colleagues so long you are in the control room ! IMHO: this should became an official prescription in the shift regulations, that only a shift leader would speak loudly among 20-25 shifters. It is rather hard to stand for several hours many various discussions around neighboring desks.

Computer on shift: pc-atlas-cr-03

pc-atlas-cr-03.cern.ch   (IP: 10.144.36.252)

This computer has many restrictions to use the web and not allows to arrange the bookmarks. frown

KSnapshot: How to arrange the snapshots?

All pictures you would like to make with the KSnapshot will be saved under the crlum username. As a usual shifter you can arrange these pictures (for example to remove them, or put in a certain subdirectory) ONLY from the KSnapshot application ITSELF. Pressing "Save as" a pope-up window with a list of files and directories will appear. A "New Folder" icon could be found on top near the "Home" and "Reload" buttons. To remove the picture - select it with the mouse, then right mouse click and select "Move to Trash".

Actual Magnets Settings: where to find?

It is useful to know which magnets are ON or OFF.
Look in :
http://pcatdwww.cern.ch/atlas-point1/operRef.php?subs=magnets/
and click on "Magnet system overview" there.

To find out the current magnets status: open web page https://pc-atlas-www.cern.ch/operation.php and click on Magnets in the Infrastructure column or walk to the DCS desk and ask the DCS shift person there.

Magnets settings for LUCID: where to find?

Switch to   DCS manager (FWD DCS FSM)   click on FWDLCD and check the HIGH VOLTAGE SET in the middle of the screen.  

L1 Trigger Rates: where to find?

Look in:
http://pcatdwww.cern.ch/atlas-point1/operRef.php?subs=systems/geninfo/trigger.html
Here click on "Trigger Rates" and then on "L1 Rates"
OR
In   "DAQPanel"   click on the   "Trigger Presenter"   button and wait till the pop up window named "Trigger Rate Presenter" will appear.


OR

  • Start x-terminal
  • Execute source /det/l1calo/scripts/setup.sh
  • enter l1rates

Trigger Presenter in "DAQPanel" does not works

* In left side of the   "DAQPanel"   find "TriP Opt" field and enter /atlas/moncfg/tdaq-02-00-03/trigger/trp/trp_gui_conf.xml there.

  • If this configuration is not passed along with the other configurations in the TDAQ panel the Trigger Presenter will return empty rates.

History of run messages, alarms, etc: LOG MANAGER

In   "DAQPanel"   click on the   "Log Manager"   button and wait till the pop up window named "Log Service Manager" will appear.

The only solution is to call system administrator: 164851. Be ready to report the LBCF desk PC name: pc-atlas-cr-03 which you find also typed on the keyboard.

LUCID pedestals & calibration

Some suggestions for existing instructions from Carla Sbarra

Pedestal and Calibration runs
To be done daily, during inter-fill time (if any)

Actions order:

  1. preparation for standalone pedestals&calibration;
  2. pedestals run;
  3. calibration run (IMPORTANT: first pedestals run, then calibration);
Time needed: ~45-60 minutes ! (~ 15-20 min. for pedestals + ~30-40 min for calibration)


Before taking Pedestals & Calibration run:

  1. There is no need to check Lucid HV settings being on shift.
    The HV settings which must be appropriate to the current B-field configuration are set AUTOMATICALLY under the experts care.

  2. make sure LUCID is disabled from the ATLAS partition
    If RUN is stopped, all subsystems must be marked in grey color on the DAQ monitor. If you are not sure that LUCID is disabled then ask the DAQ shifters.

  3. Setup the DAQPanel as follows:

    • Setup script :   /det/lucid/tdaq-02-00-03/setup_calib.sh
    • Partition Name :   lucid_calib
    • 'DataBase' file :   /det/lucid/tdaq-02-00-03/oks/tdaq-02-00-03/lucid/partititons/lucid_calib.data.xml
    • OHP configuration file :   -c /det/lucid/ohp_calib.conf.xml

  4. Click on Read Info button.
    The tabs on the right side of the DAQPanel will be activated and colored.

  5. Wait a bit these tabs are activated.

  6. Click on tab StartPartition

  7. Wait for the pop up "RunControl GUI" window to be displayed. (This should take around 10-20 seconds)

Take the pedestals run:

  1. In the pop up "RunControl GUI" window look for the Run Information & Settings panel (left, middle)

  2. Click there on the Settings tab at the bottom of the Run Information & Settings panel
    to set parameters for the pedestals run:

    • Set "MaxEvent" to 300 000; (the run will stop by itself when done)
    • Select "RunType": Pedestals;
    • Beam type: "No beam" or "Protons";
    • Beam energy: put value in "GeV" if any;
    • Tier0 Project Name: data09_calib
    • "File Name Tag": write pedestals; (DO NOT USE dots, blanks and other special symbols)
    • Recording: mark "Enable writing of the output file";

    • Click on the Set Value red box to commit changes;

  3. Follow the   BOOT   →   INITIALIZE   →   CONFIG   →   START procedure carefuly
    from the Run Control Commands panel (top left) of the "RunControl GUI" to start the pedestals run.

  4. when the run actually starts, a pop-up window will appear asking you to enter details about the run in the E-LOG.

  5. Write the details of the run here like: "pedestals". Put extension information if needed.

  6. Check the pedestals run progress
    under the Counters tab of the Run Information & Settings panel inside the "Run Control GUI".

  7. press OHP button on the DAQPanel
    to check everything is fine looking at the histograms. Pedestal histograms should show gaussian-shaped distributions. Beware that different histograms are filled at different time, so that at least 5 minutes MUST elapse before you can see ALL histograms.

  8. Wait untill pedestals run will be finished collecting ~300 000 events.

Take the calibration run:

  1. In the "RunControl GUI" window look for the Run Information & Settings panel (left, middle)

  2. Click there on the Settings tab at the bottom of the Run Information & Settings panel
    to set parameters for the calibration run:

    • Max Events: put zero-value: 0. This "0" means, there is no max. number of events to collect and you must control the collected statistics by yourself.
    • Run Type: Select CalQDC.
    • Beam type: "No beam" or "Protons";
    • Beam energy: put value in GeV if any;
    • Tier0 Project Name: data09_calib
    • File Name Tag: type in: "calibration", or something like this. AVOID dots, blanks and other special symbols !
    • Recording: mark "Enable writing of the output file"
    • Click on the Set Value red box to commit your changes

  3. Let calibration running for 30 minutes or so to collect enough statistics. You'll have to stop the run: either once all histograms have at least 150000 entries , or when you can see new points in the DCS trending plots.

  4. Calibration histograms should show single photo-electron spectra.
    Beware that different histograms are filled at different time, so that at least 5 minutes MUST elapse before you can see ALL histograms.

  5. At the end of each run, results are sent to DCS.
  6. Look at the corresponding trending plots in the LUCID DCS display to make sure nor the pedestal MEANS or the pedestal RMS changed significantly from previous runs. If so, please WARN the TDAQ-Expert (16 2443). Calibration values ought to be around 15. If not, check the fit chi2 and WARN LUCID TDAQ on-call expert (16-2443)

When both pedestals and calibration runs done (before data taking):

  1. perform the UNCONFIGURE, TERMINATE and SHUTDOWN transitions

  2. close the GUI.
    (IMPORTANT: to close the GUI before further actions !)

  3. Answer YES when asked if you also want to shutdown the partition infrastructure.
    (IMPORTANT: to shutdown the partition infrastructure).

  4. Reset the DAQPanel for Combined ATLAS run

  5. Tell the ATLAS DAQ shifter to RECONFIGURE ALL LUCID branches
    ( IMPORTANT: ALL LUCID branches must be not only included but RECONFIGURED )

  6. Check L1 Trigger prescales are set for the appropriate data taking.
