  • Simulation (mcsmear)
    • fADC timing
      • Uses threshold crossing time rather than FPGA-ish algorithm
      • Resolution is too poor
    • mcsmear doesn't mess up data enough
      • TDC timing resolution is too good
      • single photo-electron peaks in energy spectrum
    • spikes in time histogram at low energy
    • max ADC amplitude (12 bits?)
    • Sampling fluctuations not applied on per-particle basis
  • Timewalk corrections
    • Establish procedure for doing these corrections based on simulated data (how closely should this match the correction procedure for real data?)
    • Determine form of timewalk corrections
    • What if we have TDC info only on one end?
