Cosmic Simulation in rel 13: Samples


  • These samples are produced on the batch system.
  • Two filters: CosmicGenerator constrains the production vertex and direction of generator-level tracks, G4CosmicFilter requires simulated hits inside a certain volume.
  • Details and instructions can be found here: HowToSimulateCosmicIn13
  • Earlier samples/releases: HowToSimulateCosmicIn1250
  • Future samples will likely be part of official production via Simulation/SimuJobTransforms/scripts/
  • First Release 14 samples can be found at: CosmicSimulationSamplesRel14

List of geometries used:

  • ATLAS-Comm(NF)-01-00-00 (aligned, CSC-00-00-00)
  • ATLAS-Comm(NF)-02-00-00 (misaligned, CSC-00-01-00)
  • ATLAS-Comm(NF)-03-00-00 (M4/M5 setup)
  • where NF means "no magnetic field"

List of simulation filter volumes used:

  • Muon (all of Atlas, geant volume is MUONQ2::MUONQ2)
  • Inner Detector (including end-caps, geant volume is IDET::IDET)
  • TRT barrel (geant volume is TRT::BarrelOuterSupport)
  • SCT barrel (geant volume is SCT::ThShieldOuterCly)
  • Pixel barrel (has to have hits inside geant volumes TRT::BarrelOuterSupport and Pixel::Pixel)


Production with Muon Volume

  • ATLAS-CommNF-01-00-00, 57755 events at: /castor/{100-120}.root
  • Simulation output can be found at: /castor/{100-120}/sim.root

Production with Inner Detector Volume

  • ATLAS-CommNF-01-00-00, about 40k events for testing for TRT end cap calibration at: /castor/*.root

Production with TRTBarrel Volume

  • 2469 events at /castor/
  • 950 events with 5 MeV cut for secondaries, at /castor/

FDR-2 cosmics:
  • Samples made with, ~52000 events, simulated with ATLAS-Comm-01-00-00 adding alignment tag CMCCOND-CSC-00-01-00, in /castor/ . CaloNoise is on.
  • Two old files: Digitized with same geometry: dig.fdr2_trtbarrel100.root and dig.fdr2_trtbarrel125.root
  • Digitized with ATLAS-CSC-02-01-00:*.root
  • Location of bytesteam files: /castor/

  • Large sample for ID alignment group: ~100k events /castor/*.root
From dig.trtbarrel_ma_B600.root a new simulation option is tested. Please report any differences you find between <500 and >500 files!
  • This has been re-digitized in to pick up a better version of TileSimAlgs, and Calo noise has been turned on. Location: /castor/*.root

  • Large sample for ID alignment group: 299806 events at /castor/*.root

  • 11477 events on /castor/ , where X={100,450}
  • The same events (a little fewer) re-digitized with doCaloNoise = True in /castor/
  • (Be careful with similar but smaller files in /M4/, this directory also contains crashed files.)

TileCal samples, ATLAS-CommNF-03-00-00:

  • Made by Francesc Vives, these were simulated+digitized with 13.0.40 and reconstructed with The difference is in the time between simulated hits, by changing SetDeltaTHit(stepsize) in Simulation/G4Atlas/G4AtlasApps/python/
  • Step size 1ns: (default): /castor/ , aprox 64k events.
  • Step size 0.2 ns: /castor/, approx 73k events.

Production with SCT Barrel Volume

  • Large sample for ID alignment group: (in progress) /castor/*.root

Production with Pixel Barrel Volume

  • Filtering on the overlap between TRTBarrel and full Pixel volume.
  • ATLAS-CommNF-01-00-00, 4643 events at: /castor/, and dig.sctandpix108.root (sorry about the naming ...)

  • 2234 events at /castor/

  • 2396 events at /castor/

Small stat samples outside of castor:

  • /afs/, dig.trtbarrel_ma100.root, and dig.trtbarrel_ma_B100.root
