- 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
