Agenda
- Hybrid calorimeter simulation update
- (ST) I modified the simulation to mimic what GlueX at 5x10^7 might look like. I assumed that the tagger hodoscope channels below 6 GeV would be turned off and the electron beam current would be 1.1 micro-Amps. The size of the insert is now 51x51 (instead of 59x59). The threshold for FCAL showers is 100 MeV; for BCAL showers it is 30 MeV. Any events with a shower with a peak position inside the inner "ring" of blocks (x<7.26 cm and y<7.26 cm) were vetoed. The plots below show the measured 4gamma mass distribution after a 0.01 |MM^2| cut with no other requirements on the showers (left), with a veto on BCAL showers (middle), and insert-only (right). Tagger accidentals were included and subtracted.
