INPUT FILES FOR MCH CLUSTER MAPS

INPUT FILES: o2sim_geometry-aligned.root MC_QC.root DATA_QC.root

Aligned Geometry File

  • Simulation to obtain the alignement of the muon spectrometer:
o2-sim-serial --timestamp 1663632000000 -n 10 -g fwmugen -m HALL MAG DIPO COMP PIPE ABSO SHIL MCH MID
  • The output file produced: o2sim_geometry-aligned.root

MC file

SIMULATIONS:

  • Go to lxplus : ssh -X [email protected]

  • Source the environment : source /cvmfs/alice-nightlies.cern.ch/bin/alienv enter VO_ALICE@O2sim::v20230413-1

  • Create a new repository for your simulation

  • Check for the generator file : O2DPG_ROOT/MC/config/PWGDQ/external/generator/GeneratorParamPromptJpsiToMuonEvtGen_pp13TeV.C choose the right one

  • Run the command inside the simulation repository :

  o2-sim --timestamp 1669594219618 -j 4 -n 5000 -g external -m HALL MAG DIPO COMP PIPE ABSO SHIL MCH MID -o sgn  --configKeyValues "GeneratorExternal.fileName=$O2DPG_ROOT/MC/config/PWGDQ/external/generator/GeneratorParamPromptJpsiToMuonEvtGen_pp13TeV.C;GeneratorExternal.funcName=GeneratorParamPromptJpsiToMuonEvtGen_pp13TeV()"

DIGITS (this can be done locally with O2 Enviroment):

 o2-sim-digitizer-workflow -b --sims=sgn

MC RECONSTRUCTION (this can be done locally with QC Environment):

o2-mch-reco-workflow -b | o2-qc --config json://./qc-mch-clusters.json --local-batch=MC_QC.root | o2-dpl-run -b
  • The output file produced: MC_QC.root

Data File

DATA RECONSTRUCTION (this can be done locally with QC Environment):

o2-ctf-reader-workflow --ctf-input /Volumes/LaData/alice/data/2022/LHC22t/529691/compact -max-tf 10 --onlyDet MCH \ | o2-mch-reco-workflow --disable-mc --disable-root-input \ | o2-qc --config json://./mch-clustermap.json --local batch="DATA_QC.root"
  • The output file produced: DATA_QC.root
