  • 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



Rakitha's trigger curves based on HallD hadron generator


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

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