Minutes

• Updates on pion detector studies (Elham)
  • energy spectrum of electrons or pion reaching lucite with 48.5" or 56" cutout in aluminum plate is unchanged -> no shifting around of rate
  • there is suppression of low energy electrons when tilting and shifting the showermax
  • Monte Carlo efficiency on pions is only 1600 / 500k
  • Rate at the pion lucite PMT plane, detector 29, but should be placed more upstream than in these simulations
  • hit.p < 2 MeV and hit.p > 2 MeV is not a clean separation since we can still have mixtures of these
    • instead of using *any* hit, we should use *all* hits or *highest* momentum only
• Beam generator simulations (Raj)
  • photo-electrons in beam simulations are not dependent on size of lucite detectors, which is good-ish(?)
• Modular RICH idea? https://www.bnl.gov/aum2018/content/workshops/Workshop_1e/XSun_mRICH_R&D.pdf
