1. Hall A DAQ meeting January 12 th 2015

2. Summary summary GMp /DVCS BCM / Unser Raster Summary Compton EDTM F1 TDC Halo monitor Gas Cerenkov SBS Fastbus SBS GEM readout FADC/ARS test stand BigBite DAQ

3. To do list / Gmp DVCS https://docs.google.com/spreadsheets/d/1XJC vkLtSNXv9YiQ03gXwI_OkozhJdkWlD1IlxgIPtw w/edit?usp=sharing https://docs.google.com/spreadsheets/d/1XJC vkLtSNXv9YiQ03gXwI_OkozhJdkWlD1IlxgIPtw w/edit?usp=sharing

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

5. 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

6. Raster current plots

8. 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

9. EDTM Working in LHRS Need automatic start Need adjust priority Change to ROC DP server ? External script driving EDTM

10. F1 TDC Need tested spares Duplicate signal for important signal ? Cabling clean-up Power / heating

11. 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

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

13. 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

14. 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 SRS : readout UDP packet, need decoding program

15. FADC/ARS test stand 2 nd floor counting house FADC, CTP, SSP, new TI Intel CPU Need CODA setup and cabling

16. Bigbite DAQ 2 FB crate Computer srcdaq setup Portserver CPU booted Need setup FB readout and TS crate Need setup GEM crate
