How-to: HI L1 Trigger Emulation Setup in CMSSW

Complete: 5

Goal of this page

This page explains how to set and run the L1 emulation on HI events on RAW data (real data or MC). For a general description of the CMS L1 trigger look in the CMSSW SW guide here.

Instructions

Set the workspace for running the L1 emulator and creating L1 trigger TNtuple

1. Copy /afs/cern.ch/user/g/guiducci/public/rerunL1 in your local area
2. source setup_l1ntuple.sh CMSSW_4_4_0_pre8 (will get CMSSW with L1Ntuple and L1Trigger/Configuration stuff)
3. cmsRun l1EmulatorFromRaw_RAW2DIGI_L1_L1Ntuple.py (will produce the Ntuple)

Make tuples from the original trigger products (without doing a re-emulation of the L1)

  • assuming you are running over RAW data you have to ran the raw2digi step, as the trigger digis are needed.
One has to change in the l1EmulatorFromRaw_RAW2DIGI_L1_L1Ntuple.py above:
A) process.l1NtupleProducer.gtSource             = cms.InputTag("gtDigis") 
B) process.l1NtupleProducer.gmtSource          = cms.InputTag("gtDigis") 
C) process.schedule = cms.Schedule(process.raw2digi_step,process.L1Ntuple_step,process.endjob_step)

Run L1 emulator + HLT + openhlt analysis on Data

cd CMSSW_4_4_0/src
cvs co UserCode/CmsHi/HiHLTAlgos/scripts/setupL1HLT44X.sh
./UserCode/CmsHi/HiHLTAlgos/scripts/setupL1HLT44X.sh
cmsRun CmsHi/HiHLTAlgos/test/l1EmulatorFromRaw_RAW2DIGI_L1HLTJet.py

Global tags to be used

See Global tag explanations - HN HI

Example to work on the ntuples

Produce the raw comparisons between different L1 trigger variables from the 2 files: compare.py

python compare.py ntuple1.root ntuple2.root

Fill trigger bit occupancy histograms: trigerbits.C

 
start root: type  l1analysis.sh
then:
root [1] .L trigbits.C+
root [2] trigbits b("mytree.root")
root [3] b.run(-1)

HowTo's/WhereAre's

What 'cuts' are included in a certain L1 path

  • start on the page with available trigger menus here
  • click on the Link
  • in the Summary, follow the second bullet, for the HTML view of physics algorithms and scales: the page with all available triggers and the bits assigned to them opens
  • clicking on one trigger will point you to the definition of each trigger;
  • for phi/eta coverage (the green boxes), if you move the cursor over them it will tell you what eta/phi they correspond to

Use L1 menu from XML file

  • check-out package: addpkg L1TriggerConfig/L1GtConfigProducers
    • copy the xml file with the L1 menu to directory L1TriggerConfig/L1GtConfigProducers/data/Luminosity/startup
  • check-out package: addpkg L1Trigger/Configuration/python
    • edit L1Trigger_custom.py (cvs) and change customiseL1Menu(process):
      • l1MenuSource='xmlFile'
      • put the name of the new menu in useXmlFile = 'nameOfL1menu.xml'
  • in the config file you are running, add these 2 lines:

Run the L1 re-emulation for muons (CMSSW_44x)

  • due to no proper emulation of the CSC trigger primitives in combination with the CSCTF, one has to use the 'old primitives' and re-emulate just the tracking part;
  • the PTLUT changed this year with respect to last year, so we have to change back
  • so to set all these, one has to:
   cvs co -r HEAD L1Trigger/Configuration/pyhon
   cp /afs/cern.ch/user/m/mironov/public/dragosh/L1Trigger_custom.py L1Trigger/Configuration/pyhon/

"2012 L1 HI menu for the pPb run": development area

The starting point is L1Menu_Collisions2012_v2, the L1 menu used in pp and also recent pilot pPb run. The red ones are the proposed new bits to be implemented.

"2011 L1 HI menu": development area

  • create here the list of triggers to go in the 2011 HI L1 menu; i start from GlobalTriggerMenu_L1Menu_Collisions2011_v5 (last pp menu), found here here
  • taken out some triggers that we know for sure we won't use:
the jet and EG L1 settings do not really matter.
All jet and EG L1 triggers are essentially min bias triggers in HI
since there is ET all over the place.

For jets any threshold near ~20 ~30 ~50 will do, and for EG we just need the EG5 (~ish)

For muons we need:
SingleMuOpen SingleMu0 SingleMu3
DoubleMuOpen, DoubleMu0, DoubleMu3

The special HI min bias triggers from last year:
Everything with BSC, HF or ZDC in the name.

We need the ETT triggers 30 60 and the highest possible number 4TeV?

For UPC's we need:
(ZDC_plus OR ZDC_minus) AND !(BSC_Threshold1) AND SingleMuOpen
and
(ZDC_plus OR ZDC_minus) AND !(BSC_Threshold1) AND SingleEG2

Everything with Tau Tripple or Iso in the name can go.
Also all Cross triggers can go.
