Latest revision as of 08:28, 14 September 2022
- Updates
- Helicity
- ready to try to test communicating with injector
- would like to do today or tomorrow : patch helicity in BCM for quick check of helicity in main and parity
- will check helicity scalers at the same time
- software for helicity decoding : needs to push latest version after a few checks
- new helicity decoding board : moved forward with board production, Hall B was testing, will check if they had issues. One used in UITF looks fine
- HCAL
- no updates but
- Coincidence trigger
- HCal different PMTs supposed to be 10 ns difference, up to 40 ns difference (maybe due to front end or cables,mostly bottom part ) , Jiwan looking more into it, width ~ 50 ns
- BB shower
- stable for DAQ
- 1 PMT base replaced
- need to take run to check, looks He3 stable on scope
- new calibration procedure automatized , will look at latest
- He3 target
- need any variables besides EPICS
- seems only EPICS : need list of variables for start / end of run and EPICS logger
- BB GEM
- BB GEM stable
- New firmware for Common Mode calculation, using same alogorithm off line off by 3 ADC values , Ben checking
- SBS GEM
- taking cosmics
- working on merging with main DAQ
- stability issues fixed disabling 2 APVs ( out from acceptance )
- Helicity
- Fixed issues
- platform freezing ? Bryan increased the open files limit to 2000 siggested to increase to 4000, sockets time out after two minutes : better reset before powercycling and not reset two minutes after cycling
- TS to TI connection for SBS GEM rocs : Anu changed transceivers
- Pending issues
- DC1 crashing with SBS : buffer might be need to set higher value, in log slave readout list using port 5 inserting dummy data ( can comment or remove )
- HRS beam crate fiber lost : will check
- hodoscope crate making in config without GEMs : might be limited because of buffer level and trigger
- Plan
- put SBS DAQ in main DAQ
- test high data rate with several event builder
Beam planned for Sept 26
