Interface Board

• Overview
• Specifications(Version 0.99) as supplied for summer '00 test beam.
• Results from CERN test of Nov. '00
  • Response to fixed CIS signal for 48 channels (high gain). Three channels from one digitizer Tile DMU chip have a large pedestal and three channels are unused. The labeling of two unused channels is shifted by one because of a minor firmware problem.
  • Pedestal for 48 channels (high gain, low gain)
  • System noise for 48 channels. The "high frequency noise" corresponds to the RMS of the 9 pedestal samples within an event. The "low frequency noise" corresponds to the pedestal variation from event to event.
• Radiation requirements
  • Simulated radiation levels over 10 years at z=150 cm, as of 11/18/00
    • Total ionizing dose 0.23 Gy (0.023 Krad)
    • Non-ionizing radiation 1.5 x 10¹⁰ 1-MeV-equiv-neutrons/cm²
    • Hadrons above 20 MeV 6.3 x 10⁸/cm²
  • Results from SEE testing
