From Hall A Wiki
https://hallaweb.jlab.org/wiki/index.php/SBS_DAQ_meeting_summaries
- Updates
- HCAL
- DVCS LED pulser can be used and controlled
- One trigger separated for cosmics and overlapping - now 3 triggers LED, summing and cosmics
- VME DAQ working : -10 to +10V sent to modified discriminator - working as expected - GUI developped and working to control the DAC
- BB F1 tested was working with SD board : trigger input seems ok and board working
- labeling and inventoring for move on May 17th - uncabling on Monday
- will try to take last run
- keep computer in Scott's office for now - will try to set up network and extension cord to get thing started in Hall
- BB Shower
- not tried TDC yet, will try to put it in again - Scott will try to send a scope picture of trigger signal going to F1
- can try to set up another F1 trigger by TI
- taking cosmics data with shower
- Bigbite going on May 17th in Hall - most likely start to take apart next week
- BB Hodo
- still taking data every day
- getting ready for move
- documentation almost done
- GRINCH
- Gasket installed ready to be sealed
- testing LED : pulser old and started to have issue - need another pulser - HP8160A programmable pulse generator -
- VETROC decoder might still need tweaks, cannot see the top PMTs
- still need to fix ADC readout - need to define geographic adress - Mark updated the read out list - should work now
- planning for move
- CDet
- Ralph found issue with ADC : connector going from MAPMT to NINO, each connector has 8 pins, signal and ground for one pixel was loose - made other pixels ground floats hence pedestal shift - new cable fixed issue
- taking cosmics
- LHRS
- detector cabling to DAQ
- GEM TEDF
- will set up to run cosmics this week-end
- Bryan finished up porting SSP readout to VTP - need to generate config files
- issue with MPD connection to VTP - Ben trouble shooting ( might be issue with interface board )
- Optical card added - sbsdaq1 or 2 - will set up second board in sbsdaq1 or 2 ( the one used for GEM )
- GEM INFN
- constructed faraday cage on J3, saw same improvement of noise as in UVA setup
- thinking of plan to implement that on all chambers
- one VME SD in INFN - Ben will cable it when he gets
- GEM UVA
- brought back MPDs from electronics group, all have terminators
- Bogdan and Nilanga designing shielding frame
- working with Ben tracking GEM noise
- Helicity
- Paul has questions , will follow later
- HCAL
