keyword=Scintillator trigger efficiencyFrom run 4283, taken with the Ta elastic peaks ALMOST off the upper edge of the focal plane, the scintillator triggering-efficiency was calculated using the T1/T2 and T3/T4 events. Plots of the triggering in-efficiency for the L-HRS are shown in Figure 1, for S1 in the upper panel and S2 in the lower panel; the same thing for the R-HRS is shown in Figure 2.
For single-track events with a delta-cut of +/-4.5%, it looks generally okay: at the extremes (around +/- 1m) the efficiency begins drop appreciably.
