Transcript

  • 1. Discussion on Geometries FCAL Collaboration Workshop TAU, September 18-19, 2005 Christian Grah
  • 2. Coordinate systems Coord.-System 2: Geant4 like (Mokka): Coord.-System1: Geant3 like (Brahms):
  • 3. Positions/Geometries
    • Center Lumi- and BeamCal on outgoing beam.
      • LumiCal: ± 3.05cm
      • BeamCal: ±3.65cm (z=370 is also used)
    • Angular Coverage:
      • LumiCal: 8(13) to 28cm 26(43) to 92 mrad
      • BeamCal: 1.5(2) to 10(16)cm 4(5) to 28(44)
    • Option: misplace BeamCal and keep aperture small...how to prevend dead area?
  • 4. BeamCal Segmentation 45/60° calo segment (nseg=8/6) using 360-opening angle/nseg for 20 mrad
