1. M. Fincke-Keeler Univ. of Victoria LArg week - Feb. 20051 Simulation of 2002 H6 Testbeam in Athena Basic 2002 H6 testbeam simulation is implemented in Athena: LArCalorimeter/LArG4TB/H6G4Sim/share/jobOptions_2002H6G4Sim.py LArCalorimeter/LArG4TB/H6G4Sim/G4macros/H6G4LArCal2002.mac LArCalorimeter/LArG4TB/LArG4TBH6/src/LArG4TB2002H6.cxx In order to run it, cmt-check-out the packages : LArCalorimeter/LArGeoModel/LArGeoCode LArCalorimeter/LArG4TB/H6G4Sim LArCalorimeter/LArG4TB/LArG4TBEmecHec LArCalorimeter/LArG4TB/LArG4TBEndcap LArCalorimeter/LArG4TB/LArG4TBExpHall LArCalorimeter/LArG4TB/LArG4TBH6 LArCalorimeter/LArG4TB/LArG4TBHEC (LArCalorimeter/LArG4/LArG4EC )

2. M. Fincke-Keeler Univ. of Victoria LArg week - Feb. 20052 The H6G4Sim package uses the “ParticleGenerator”. To choose the properties of the beam, refer to e.g.: http://atlas-sw.cern.ch/cgi-bin/viewcvs-atlas.cgi/offline/Generators/ParticleGenerator/doc/ParticleGenerator.pdf

3. M. Fincke-Keeler Univ. of Victoria LArg week - Feb. 20053 The output is a Pool file, which contains: EventInfo (EvenId: run#, event# // Event type ) LArHitContainer ( = id, Energy, time ) CaloCalibrationHitContainer ( = id, Energy(4) ) The fine print:…. At the moment the HitContainers are only filled for the detectors. (AtlasG4Sim/HitAthenaPoolWriteOptions.py is invoked in jobOptions) TB-specific elements are not included. Can be read with a program like: LArG4Analysis

4. M. Fincke-Keeler Univ. of Victoria LArg week - Feb. 20054 What needs to be done: Implement H6 TB-specific entries into the Pool File Fill the Hits into CaloCells and produce ESD’s such that LArG4TB generated events can pass through the same analysis chain as TB data.
