APEX DAQ and Trigger
From Hall A Wiki
- Florian's plan for APEX trigger setup
- Here is trigger information for APEX.
The triggers are plugged into the Trigger Supervisor on the R-HRS. The prescale factor is controlled by the GUI "prescaleR". Run this GUI from the adaq account on adaq2. Trigger definitions for APEX Let S0A and S0B be the 2 pmts of S0, a vertical scint. and S2L and S2R are left and right PMTs of an S2 paddle and S0=S0A&S0B = the "and" of 2 pmts and S2=S2L&S2R = the "or" of [left&right] pmts then T1 = LHRS S0&S2 with S2R timing T2 = LHRS S2 with S2R timing T3 = RHRS S2R (right PMTs only) T4 = RHRS S0&S2R with S2R timing T5 = RHRS S2R&GC with S2R timing T6 = Coincidence = T2&T5 with T2 timing for trues T7 = SciFi cosmics (one trigger for both arms) T8 = LHRS Clock (103.7 kHz) T9-T12 empty
