1. CLAS12 trigger development for next few years:
- ECAL/PCAL clustering: attenuation is not a problem, can continue to use ideal 376cm; problem with fake clusters because of timing resolution is not good enough, too loose dalitz and decaying clusters; mip energy clusters can be lost in current algorithm; we may need to redesign clustering completely, will continue discussion; may use level1 and level3 together
- DC trigger will stay as is, more efforts will be done on level3
- multi-track trigger in stage2-3 ?
- it is unclear if we really need to improve trigger purity, or we can leave with existing trigger (at least until 2022)
2. HPS status:
