BCM / unser
• UNSER
• New BCM– Not count at 0 current (might be negative offset )– Saturate at 30 uA ( Optimize for DVCS or GMp)

Raster
• Overall works– Need check saturation ( double blob )– Spikes– Should be ok for DVCS and GMp ( issue for He3)
• https://logbooks.jlab.org/entry/3313730

Compton
• Integrated DAQ being worked• Counting DAQ photon ?
• Edet : – Plan stand/ semi standalone DAQ– Need BPM, cavity power – Could fit in CMU crate or use separate crate– Need setup EPICS : motion and detector– Replace detector and survey

EDTM
• Working in LHRS• Need automatic start• Need adjust priority• Change to ROC DP server ?• External script driving EDTM
![Page 10: Hall A DAQ meeting January 12 th 2015. Summary summary GMp /DVCS BCM / Unser Raster Summary Compton EDTM F1 TDC Halo monitor Gas Cerenkov SBS Fastbus.](https://reader036.fdocuments.us/reader036/viewer/2022062518/5697bf7c1a28abf838c840a4/html5/thumbnails/10.jpg)
F1 TDC
• Need tested spares• Duplicate signal for important signal ?• Cabling clean-up
• Power / heating
![Page 11: Hall A DAQ meeting January 12 th 2015. Summary summary GMp /DVCS BCM / Unser Raster Summary Compton EDTM F1 TDC Halo monitor Gas Cerenkov SBS Fastbus.](https://reader036.fdocuments.us/reader036/viewer/2022062518/5697bf7c1a28abf838c840a4/html5/thumbnails/11.jpg)
Halo monitor (GMp)
• Proposal– 4 fingers ( scintillator or quartz )– Fast electronics group discrimiator ( 3 K$ 16
channels)– EPICS readout
• Most likely halo will be fine if it can go through Compton

Gas Cerenkov
• Mysterious inefficiency for bad runs– Photons ?
• Do we want to put 1 FADC for readout ?

SBS Fastbus
• 3 FB crates• V1495 ready• New TI
• Test flipping and sync with 3 new TI• Could test with 6 crates ( 3 TI master + 3 TI
slave )– Need setup 6 crates– Order optical fibers

SBS GEM
• 1 VXS crate UVA• Bryan working on MPD ( 1 month depending on
priority )• INFN software working
• Need– Start development optical link / SSP readout
