Meeting General Agenda

Oct 9th 2014 meeting

  1. Report relevant updates from 7:50 and 8:00 daily MCC meetings:
    • Accelerator schedule: The probable date for locking the Hall is around Oct. 17th.
  2. Report on Work in the Hall:
    • The upstream platform is now a hearing protection area. Hall D is a radiation aread. OSL need to be worn everywhere in Hall D.
    • There will be a 2h power outage Friday at 7:30am in Hall D (tagger area is not concerned).
    • Elton will give a SAF113 walkthrough today at 9:30am.
    • Tim will give a solid target training Friday after the coordination meeting.
    • Yi will give a solenoid training today after the coordination meeting.
  3. Hot Check OUT Status 19% ready ; 48% checked ; 33% not ready
  4. Installation punch list (items in red: must by Oct 6th ; Blue: Done by 2nd Fall run; Green: Nice to have it
    • Pair converter
      • The wire is installed. Tom measured the wire diameter without insulation to be 200 microns.
      • Chamber is closed and under vacuum, leak-checked and ready to go.
    • Pair spectrometer detector - Positioned on the stand. Survey is done.
    • Profile monitors -
      • The two profilers are now installed and surveyed.
    • Active collimator -
      • Cables are terminated and in the Hall. All hardware work is completed.
    • Target/Start Counter
      • The light leaks of the SC are largely fixed. SC is mounted back.
    • Tagger shielding - Wall (final labyrinth configuration) almost complete. Both small walls are done. Need to add iron shielding near the photon photon dump.
    • Pair Spectrometer Magnet remote control - Control is now working.
    • Pair Spectrometer Magnet Field readout Done, but the Hall probe reads only 1/2 the expected field.
    • Survey:
      • FDC
      • Collimator
      • Pair Spectrometer detector: finishing today.
      • Upstream Profiler in collimator cave.
      • Start counter: Survey should be done by the end of the day.
      • FCal: Still working on it. Should be completed today
      • CDC: Should be completed (confirmation?).
      • Microscope
      • Beam pipe section
    • Vacuum - Done.
    • Amorphous Radiators - FSD done and tested.
    • Halo Counters - All are installed. The 8 in the Hall are successfully readout. The 7 in the tagger Hall are not readout yet. It is unsure that they will be ready for the 17th.
    • Microscope - Microscope is in its correct position. Today, Alex B. will measure the dark current.
    • Tagger crates - Can now been readout. Will be removed on the 10th.
    • Hodoscope checks - Nathan is testing the detectors and electronics with DAQ. All installed counters (about ~170) have been checked with a scope. Some signs of light leaks. Nathan fixed them. 9 out of 170 counters have problems (1 not responsive, 8 with cabling problems) . Franz took them back to Catholic Univ. to fix them.
    • Radiation monitors - Gamma and neutron probes ready. Ion Chambers installed. Witness SiPM baseline characterization to be done today or tomorrow.
    • 2nd sweep magnet. (2nd collimator aperture) - not required for Fall run.
  5. Specific safety notice (from Tom/Tim/Mark): Tagger Hall: Be mindful of the wall construction work, in particular the forklift motions. Solenoid training today (low field: 50A, but Hall worker should act as if it was full field.)
