[Halla_running] Friday RC meeting in preparation for lock up

[Donald Jones]

Dear Collaborators,
The current plan is for hot checkout to happen during the day on Monday and with the Hall being locked up on Swing. On Wednesday Day we expect our first physics beam. With this in mind, experts, please have a plan to ensure that your system is ready to go prior to Monday if at all possible. We do not want to delay the efforts of operations getting us ready for beam on Wednesday because of unnecessary accesses that could have been prevented by testing systems beforehand.
I would like to have an RC meeting tomorrow (Friday) afternoon at 3:30 to discuss readiness. Please be prepared to report on the readiness of your subsystem. Identify the subsystem components and tasks from the list below for which you are responsible.

  *   Target : field measurements, target laser alignment/calibration, cell readiness, gas system for dummy target, cooling jets, foil ladder
  *   Bigbite: magnets, calorimeter, hodoscope, GRINCH, cosmic run with magnets on
  *   SBS: magnets, correctors, corrector current settings known?
  *   GEMs: gas, HV...
  *   Beamline: raster, quads, BCMs, BPMs, Ion Chambers, vacuum quality good and valves operating properly, cooling jets on window
  *   DAQs: SBS, parity
  *   Moller polarimeter: magnets, HV, DAQ, SC magnet, target motion
  *   Alarm Handler: running and sound up. All channels with active alarms understood and documented
  *   Counting House: displays up and chalkboard info transferred
  *   Kin 4 kinematic spreadsheet setup
  *   Analyzer and 50k replay ready and bug free
  *   Charge feedback: new photocathode installed with QE=0.6%. May require new setpoints to get low Aq.
  *   Detailed runplan: the RC will need to know how many hours on dummy, and different foil configurations along with any off-production field settings that are needed. Decision on what current we will be running for startup.
  *   Placeholder for what I missed....
