From Hall A Wiki
- Updates
- HCal
- started setting up summing trigger for cosmics, need more discriminators. Discriminator setup, need remote control of threshold ( check with electronics group ) - need threshold control - DAC VME board to be setup ( Chris board ) - need a long cable for setup in the hall. Need evaluate threshold for individual PMTs ( need to think of a scheme ) - could try turning some HV off - capacitive coupling ? ( need to figure out - most likely no) - need have trigger energy calibration - summing module sum of 16 - is 60 Hz an issue ? Added capacitor coupling on BigBite (20 pF)might need to do that ( but AC coupling has rate dependence ) - channel going in discriminator - 80 group - plan to have 1 more FADC for reference time - if 2 FADCs can add sum.
- HCAL DAQ upgrade to Centos 7 and last FADC library version will take a few days

- Bigbite shower
- VME crate setup : took data yesterday
- Bigbite shower
- Bigbite hodoscope
- taking runs every day - ADC and TDC spectra - was stopping at 1 M - run in VNC ok - debugging issues - s
- Bigbite hodoscope
- LHRS
- all fastbus crate working stand alone
- will put all crates together
- still need to install Centos 7
- LHRS
- INFN GEM
- taking cosmics since Wednesday - some crashes from time to time - DAQ is fine and low level plots look good - but cosmics data missing large amount
- Bryan fixed hv program but most likely not related to previous issue
- INFN GEM
- UVA GEM clean room
- still have network issues - router ordered should arrive today
- UVA GEM clean room
- GEM TEDF
- got working common noise subtraction and pedestal subtraction
- cosmics trigger setup, Sean looking at adjusting latency
- GEM TEDF
- CDet
- getting back running - missing hardware for PMTs holders
- CDet
, Peter will work on installing PMTs
- clrlpc is back : will be used for CDET DAQ
- need find TI SD and CPU and waiting for VETROCs
- GRINCH
- sealed with gasket, trying powering to check if everything is work - ribbon cable working -
- GRINCH
noisy on some cables - around translator
- CODA3 working, taking data - need to adapt decoder to look at data
- GEn RP
- putting detector together
- GEn RP
- For next week : FADC list and priority FADC wish list
