From Hall A Wiki
- Updates
- HCal
- working on FADC scalers
- GUI not working working
- Need to get set up for trigger
- Main CODA not working TS offline
- ECal
- Need 3 SDs and 2 VTPs for all ECal crates
- put FADCs from GRINCH and ECAL in VXS crates
- Hanjie finished cosmics trigger - 7 firmware for each crates - synthetized and pass to Ben to put in firmware - need to get SSP processing -
- HCal
need to check with Ben , best place for SSD - cannot go in TS crate - maybe one ECal crate - 2 SSPs in cabinet
- position dependent thresholds
- cluster thresholds - column thresholds ? X and Y position from target
- Kip plan to put together a document for cluster information - document in progress
- lookup table for coincidence - to be generated too
- Andrew has link for documents : https://sbs.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=590
- Chi-Ying working with Jiwan and Simona - will work on software to do calibration and produce the thresholds for the DAQ
- CDet
- Low Voltage supply : Mark building for CDet - Mark wanted to reach out to Ben to ask question about control of LV ,bringing engineering student to help with that too - 3 crates in small bunker - need to have connected to internet
- cable making on going
- 4 modules to be retroffited
- HV cables laid out at pivot to the setup
- bring TDC cables to be laid next week
- will install VXS crate - starting to make VETROC ECL adapter
- Beamline
- need to recable beamline
- Ciprian can work on it in November, Paul will come to upgrade parity DAQ crate could help with beamline after
- Helicity
- helicity decoding board - Paul has one to be installed - can be added when recabling beamline crate
- GEMs
- histogramming method : need to setup VTP and optical to VXS in INFN clean room to test
- testing MPD and APVs low level - Front tracker looks good, a few APVs causing issue maybe due to HDMI cable - is there a way to test HDMI cables ? HDMI tester - check reflection and bandwidth - HDMI tester not working - can do testing with MPD ? fisheye test might be a way to check the cable - using know good cables and APV and replace -
- how to figure out if digital or analog ? if all 4 analog has issues might be digital
- test resistance of cable : small test setup to check for poor contact
- checked with Ben to reload firmware at each
- work on GUI to reset APV, MPDs
- more LV channel to be installed by Lars
- MPDs : split layers between 3 VTP crates to avoid VTP network bottleneck
- Need reference time from trigger
