"Your directories included the codes I developed for SPD background rate analysis, and there do include cuts from EC.

For the MRPC, I  don't have a well maintained analysis code but this one can be a good starting point:

What we need to do is to combine the cuts from three detectors. For EC, we know the radial dependent energy cut,

and for SPD, we can use the MIP cut. However, for MRPC, we haven't have a good cut yet.

general

code

https://jlabsvn.jlab.org/svnroot/solid/study/trigger
  • In principle, trigger from different detectors should be formed independently. then they form some logic between each others to make the final trigger.
  • When coding, we should make each detector as independent function or module to ensure that. And each module can be reused between different triggers to ensure consistence
  • The time window with a detector and between detectors are important, in particular how much low energy background will contribute

trigger from detector

EC (Rakitha)

new

Rakitha's trigger curves based on HallD hadron generator

old

Jin's background embedded trigger curves files in root file and call function made by Yuxiang are at 

https://jlabsvn.jlab.org/svnroot/solid/subsystem/ec/triggerfile/

Previous EC trigger rate produced by some scripts calling Jin's trigger curves in root file, Yuxiang's call function are based on these

LGC (Michael)

SPD and MRPC on photon rejection (Sanghwa)

PVDIS e trigger (Michael, Rakitha and Rich)

EC+LGC

SIDIS e trigger (Yuxiang)

EC+LGC+SPD+MRPC (forward angle) , EC+SPD (large angle)

maybe gain experience from PVDIS e trigger first, in particular for LGC

SIDIS hadron trigger (Yuxiang)

EC+SPD+MRPC (forward angle)
