Neutron wall B analysis

  • Position calibration
    • Run by run calibration
    • Bar-by-bar position resolutions (update to GitHub)
    • Error propagation (to final spectrum)
  • Charged-particle veto
    • Crude filter (any hits on VW imply charged-particles)
    • Cone projection filter (or estimate how much % could be improved)
      • Multiplicity v.s. centrality
    • Consistent with WMU
  • Pulse shape discrimination
    • Batch by batch
    • Cause for changes between batches
    • Error analysis and time-of-flight analysis
    • Error propagation (to final spectrum)
  • Light output calibration (ADC -> MeVee)
    • Cosmic + AmBe five-point calibration
    • Bug fixed: Incorrect dimension of NW bars
    • Why the 12C(n, d) peak is not as apparent as before?
    • Bug: Kinematics is not monotonic, i.e. cut at fixed energy, yield does not decrease as theta increases
  • Shadow bar analysis
    • Correction curves have been established
    • Error analysis
    • Error propagation (to final spectrum)
  • Geometric efficiency
    • Efficiency curve for any positional cuts (shadow bars, bad bars, etc.)
  • Detection efficiency
    • SCINFUL-QMD
    • Park's Geant4 consistent with SCINFUL-PHITS: Done, but compile the presentations into one
    • Bug fixed: Included (n, 3He) and (n, 4He) that were previously excluded
    • Light responses: Experimental v.s. Geant4
    • Why the 12C(n, d) peak is not as apparent as before?
  • Event counting / normalization
    • Trigger condition
    • Random subtraction (due to high beam rate)
      • Take two batches of the same reaction but very different beam rates
  • Miscellaneous
    • Crosstalk effect (%?)
    • Neutron wall A
