Jamies Digittize Wiki

  • Trying to generate / simulate / digitize cosmics in the pit with ID and muon system 'on'
  • Had a number of problems briefly described here
  • Firstly the SCT digitization had a timing cut which meant that the SCT hits were lost at digitzation. Thanks to Richard Batley this is fixed with tag: SCT_Digitization-00-09-18 and adding the line: FixedTime=10. to the job options.
  • Now find a problem that most generated cosmics miss the ID (even if there 4-vector is required to point at the ID multiple scattering through 100m of rock means that it still misses).
  • In 12.0.1 i can generate a good cosmic event (event 6 out of 10) with the following JO:

  • Andrea Di Simone suggested writing a G4Action that required simulated hits (after generated track had been propagated) inside the Calo region. I have done this with the attached code. unfortunatly this can only work in 12.0.3.
  • Wheni run in 12.0.3 i never see any SCT hits??
