Meeting General Agenda

September 22, 2015

There will be only five weeks of beam operations, out of which there will be at least one week of beam restoration (probably more). In addition, we will have the Hall open during the day for 2 weeks or more for the magnet according to Beni. At least one week will overlap with the beam restoration. According to that, we would have at most 4 weeks of possible beam with 12 GeV priority including 1 week or more with beam only during owl and night shifts, if the accelerator agrees (I understood that Hall availability to the 12 GeV has priority over the magnet repair). Very likely, we will get much less than the schedule above.

• So far, We have on the list:
  • 4 hours for 10 days for Fast-Feedback Studies.
  • Beam line model test. (Expected time unknown).
  • Goniometer and Polarimeter commissioning.
  • Alex Somov would like as much data as possible on the PS and tagger detectors, as well as for trigger studies. Alex claims that for his basics investigation, no having the magnetic field doesn't matter. We will need to have the calorimeters, SC and TOF on during theses studies.
  • Sergei would also like to have dedicated DAQ time (a couple hours/day) since he did not get enough data in May.
  • Both calorimeters will take data (for their sake and because of the trigger).
  • Lubomir and Sergei would like to test their transition radiation set-up. It should be parasitic to other Hall D activities, but it may require a specific trigger at some point.
  • If we can get a low beam current, Total Absorption Counter commissioning could be started. However, there are some trigger and DAQ work necessary before it is ready.
• We need to decide what collimator we will use.
• Coordination of Solenoid work.
• Lubomir is not planning to run the FDC without magnetic field because the high drawn current accelerates the aging of the detector.
