August 1, 2018 online meeting minutes

present: Sergey Boyarinov, William Gu, Raffaella DeVita, Hai, Ben, Valery, Stepan

1. DAQ/Trigger upgrades progress for upcoming run

• FADC packing etc: firmware went to Ben, he implemented half section, more tests shows some problem running on hardware while simulation works fine, Hai and Ed will debug it today, it works but data occasionally corrupted, will wait one more day and if not ready will load into CLAS12 and receive data anyway to produce data file for offline team; library wave to be changed as well

• DC trigger: all VTPs are repaired and installed for DC, CND still missing; DC trigger firmware is in with preliminary dictionary, has match with FTOF in stage1 but not in stage2 yet, waiting for complete dictionary (Veronique and Mac are working on that); will start run in tagging mode and check efficiency

• VTP readout: Ben and Bryan Moffit implemented DMA-based VTP readout, ROL2 modified, can read all 42 VTPs, so far all 18 DC VTPs were read out up to 90kHz, start from Prestart should work now as well; Ben will recompile non-DC firmwares, hope to finish this week

• MVT data packing: Irakli modified ROL2 implementing data packing, will test it shortly

• CAEN TDC calibration: forward carriage and ctof are calibrated, and will be done today

• RF: have to address readout speed from v1190, maybe move it to v1290 - Sergey will look at that

• run 8 new cables from Pie tower to sector4 (for Helicity etc), will ask Pasyuk

• BAND: hps12 will be removed and installed on SF, will put SDC card in (from Ed) and Chris will supply 8 FADCs, issue can be with CPU, and need fiber from TI to TD (Chris), actually 2 fibers including future VXS crate
