Physics / analysis topics:

Overall checks / improvements

  • Overshoot at ./mu level not recorded! Needs a flag added to the TFadcPulse class
  • Overall mapping quite okay, but know misidentification for too close pulses due to large coincidence window. Example picture is in this eLog. Some pulses are also simply not recognized.
  • Fractional pixel space information is available but not used right now. Could maybe allow to reduce the time coincidence window for the mapping between FADC and TDC400 information?

Threshold / gain analysis

  • Machinery should work, FADC shrub should allow to systematically look at the
    • gain - optimal energy / stop anode energy
    • threshold - energy spectra for all green, blue or red pixels
  • Runs need to be combined to compromise between enough statistics and studying the time evolution of these parameters
  • Align gain for each run (subset of combined runs).
  • Do we have to select a certain angle range only (i.e. mainly horizontal muons)?

Capture energy spectrum

  • Cuts on capture events might need to be changed? (Side note: Can we actually centralize this cut for all analysis modules that do this (CaptureAnalysis, FADC, ...)? Maybe a general function that determines if a muon has a capture: IsCaptureEvent(TMuStop *muon)?)

Charged particle emission after capture

  • Principle candidates are easy to be found: PDF document
  • Characterization (length, energy loss etc.) needs work, Steve's latest ./mu development code would be usefule here. Not possible in current FADC shrub since no inclusion of these events (only muon2->IsSpot() at this time)
