Cosmic Simulation in rel 14: Samples

Overview

  • These samples are produced in 14.4.0 AtlasProduction on the batch system, although simulation step is also available with Simulation/SimuJobTransforms/scripts/csc_cosmics_sim_trf.py
  • The size of the ATLAS-GEO samples will be 50-100k events when finished.
  • To access the data use STAGE_SVCCLASS=atlasgroupdisk
  • Two filters: CosmicGenerator constrains the production vertex and direction of generator-level tracks, G4CosmicFilter requires simulated hits inside a certain volume - more details on the settings to come
  • Several questions lately: note that the mu+/mu- ratio in simulation (1.5) is not the same as in data. The simulation fluxes uses this reference: A. Dar , Phys. Rev. Letters 51, 227 (1983)

List of geometries used:

  • ATLAS-GEO-03-00-00 (aligned, Solenoid On, Toroids On)
  • ATLAS-GEONF-04-00-00 (aligned, no magn field)
  • ATLAS-GEO-04-00-00 (aligned, Solenoid off, Toroids On)

List of simulation filter volumes used:

  • Muon (all of Atlas, geant volume is MUONQ2::MUONQ2)
  • TRT barrel (geant volume is TRT::BarrelOuterSupport)
  • Pixel barrel (has to have hits inside geant volumes TRT::BarrelOuterSupport and Pixel::Pixel)

Samples

Production with Muon Volume

ATLAS-GEONF-04-00-00:
  • so far only a few thousand test events. Can be found at ~gencomm/w0/cosmicSim_rel14/NoField/dig.muon*.root

Production with TRT barrel Volume

ATLAS-GEO-03-00-00:
  • About 20k at /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEO-03-00-00/dig.GEO-03-TRTBarrel.*.root

ATLAS-GEONF-04-00-00:
  • 24k at /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEONF-04-00-00/dig.trtbarrel2*.root

Production with pixel barrel Volume

ATLAS-GEO-03-00-00:
  • so far only test events: ~gencomm/w0/cosmicSim_rel14/dig.GEO-03.pixelbarrel_B1.root
