• 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. Example scripts are here to process detector response in one corresponding root tree independently, then combine them for study

• The time window with a detector and between detectors are important, in particular how much low energy background will contribute

trigger from different detector

EC (Rakitha)

Previous EC trigger rate produced by some scripts calling Jin's trigger curves in root file

The scripts are

https://jlabsvn.jlab.org/svnroot/solid/study/background/trigger_EC_PVDIS.C
https://jlabsvn.jlab.org/svnroot/solid/study/background/trigger_EC_SIDIS.C
https://jlabsvn.jlab.org/svnroot/solid/study/background/trigger_EC_SIDIS_MIP.C

Jin's background embedded trigger curves files are

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

It would be nice if the part calling trigger curve can be take out and as a independent function and put into triggerfile dir

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

We have files, can start now
