Minutes of the October 02, 2015 meeting.

Minutes of the October 24, 2015 meeting.

Minutes of the Dec. 1st, 2015 meeting.

Dec. 3rd 2015 meeting

1. Report relevant updates from 7:50 and 8:00 daily MCC meetings:
   • Accelerator has steered beam through ARC6 (3 passes) by end of owl shift last night. 1090MeV per linac (=6.6GeV)
   • Machine tuning is continuing. There is a problem for a power supply in ARC 9 (faulty choke). Accelerator will switch with choke from ARC 10 in order to gain time and enable the delivery of beam with max. energy to Hall A.
   • Beam to Hall D is postponed to Dec. 8th.
   • Link to accelerator short term schedule
   • Accelerator schedule through June 2017.
2. Hot Check OUT Status 54% ready ; 3% checked ; 43% not ready
3. Report on Work in the Hall:
   • Solenoid: Wrapping up repairs. Then, the cool down will begin. During this cool down, there will be times when control or restricted accesses will be needed (disruptions for MCC since any access for us bring down the gun).
   • Surveys
   • Amorphous Radiators
   • Radiation monitors Status of shielding?
   • Halo Counters : The one on the platform has been be put back. Others are good but there is a question regarding their alignment (orientation).
   • Microscope Ready but need to do HCO.
   • Hodoscope checks
   • Active Collimator - Placed on the 5mm hole.
   • Collimator On blocking position.
   • Profiler/intensity monitor - Profiler has been updated for faster acquisition. It working but a few checks remain.
   • Pair spectrometer. Will be tested today.
   • Target Empty (i.e with H2 gas). A 1 cm plastic disk is in position at the end of the ST.
   • Start Counter There are 3 dead channels (most likely accidentally unplugged during ST motion). They will not be fixed since techs are busy with the solenoid and the ST will not be very useful for this run (target foil outside of the ST).
   • FDC
   • FCal
   • CDC One low voltage channel has its current readout dropping to zero and then coming back up. Some other channels display this sometimes too.
   • TOF
   • Transmission radiation detector
   • Slow controls. Mostly done. There are a couple of remaining things to do.
   • DAQ
   • Trigger integrating the tagger crates in the trigger.
   • Online monitoring
   • Tagger magnet, PS magnet, 2nd sweep magnet. NMR for tagger magnet is not working.
   • Goniometer
   • Polarimeter (converter is out of the way)
   • TAC
   • If you have work to do in the Hall, please notify Tom (Hall work coordinator) and if necessary, document it in the electronic logbook.
   • OSL need to be worn everywhere in Hall D.
