From Hall A Wiki
l* Updates
- HCAL
- still taking cosmics, issues with some TDC lines - some thresholds had to be adjusted
- HCAL
only 1 bad TDC channels working intermitently
- BB Shower
- taking cosmics - everything is working
- question trigger : NIM based trigger - want to have both NIM and digital -
- switch to FADC for preshower -
- need to add fiber to run both crates at the same - can run crates one at a time - now two different paddles on shower and one on preshower - will send trigger to flash crate -
- BB Shower
Bryan will work on it today for two independent DAQ
- BB Hodoscope
- tried take data run on Friday - runs looked ok - working on decoding and processing. Meeting with Mark on what to install in bbhodo account. Peter and Ed Brash helping to reuse similar to CDEt code.
- estimate a month to finalize software - should be able to look at spectrum with software - issue with cratemap and initialization of modules - Carlos will help Rachel to check - Alex will look for old stand alone script for V792.
- all channels check on scope
- need documentation and cabling scheme for installation in hall
- CDet
- previous module disconnected swapped with new module. Cleaned and PMT needs to be installed and after NINO - should be back to data taking in two week at lates
- VXS crate delivered will set it up in weldment
- GRINCH
- Bradley tested CODA3 - need to check software works with CODA3 - still just pedestals waiting for gasket -
- LHRS
- Maria Satnik working with Bob, TI boards and CPU in Fastbus, can talk to the modules, pulser test with CODA3
- upgrading to Centos 7 - need it for ATOM controller - still working on booting the CPU
- estimate 2 months until we take cosmics with HRS
- FADCs available - Fastbus still available - A1 aerogel counter 26 channels -
- GMn running still in developement : Hall B taking a lot ot 3.7 GeV time, consider calibration at beginning of run
- Helicity : new board to record and decode helicity - better to have both old scheme and new board
- trigger
- HCAL : NIM trigger and digital trigger
- LHRS : trigger from HRS - need check HRS with digital trigger
- Experiment trigger : NIM trigger baseline and digital trigger development
- GEn RP
- Moller testing : delayed helicity ? CLAS12 wanted delayed - So plan for delayed helicity
- GEM
- INFN :
- working on checking connection after hardware change - might be issue of robustness
- UVA
- EEL clean room : taking cosmics data - one MPD had issues giving errors - another MPD which was replaced is no more giving - plan to replace the MPD still giving errors- Anu planning to replace LV cables - not sure what is problem with MPD - label MPDs and record errors - how many bad boards ? Need to fix them ? Need to make inventory of MPDs with issue
- TEDF
- SSP readout working for all modules installed
- Ben tried new firmware : seems working
- one MPD has issue, not get trigger
- Holly setup VME readout for easier MPD debugging
- will take pedestal runs at different trigger rate and implement zero supression
- Zero suppression still on SSP - only plan to pack two samples in one word on mpd - expect 2.7 KHz rate for now. Right now 1.1 KHz at 100% occupancy right now ( VME or ethernet limited ) with Test configuration with few APV to check -zero supression algorithm takes away from trigger buffering -
- SSP code to look at MPD data stand alone working
- Ben will be back to MPD development for VTP at end of January
- will install software to look at VME MPD readout
- need 3 VTP for readout
- INFN :
- BB Hodoscope
