January 13, 2016 online meeting minutes

present: Sergey Boyarinov, vpk, Ben Raydo, Eugene Pasyuk, Chris Cuevas

1. Clas12 trigger

• first VTP board assembling about to start finally, will have it here in about 4 weeks

• Valery will prepare trigger requirements document, assuming that for commissioning we deliver something like (HTCC>2)*{PCAL+ECAL}>1Gev starting from HallD-style total sum, following by cluster-based trigger; more components will be implemented later in following order: FC (Forward Calorimeter), FTOF/CTOF, DCRB, optionally SVT

• trigger electronics on pie tower must be commission: 2 things to be finished: new switches installation/ethernet cables cleanup, and 6 TI replacement to ones with 6 fiber ports, will try to finish all that in a week and start commissioning; subway has all racks, crates and trigger fiber are installed, ethernet fiber team waits for multimode fiber to finish the job; HTCC/CTOF/etc crates are not on space frame yet, have to come from test setups

• FADC busy was implemented for Hall D, will do it for CLAS12 as well

• inventory is important to buy missing hardware, may take another few weeks

• Valery will talk to Mauri about playback more files for trigger development

2. Others: HPS trigger still need some fixes (latency, fadc deadtime, trigger bits) - Ben and Valery
