Meeting General Agenda

Oct 13th 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. Link to accelerator short term schedule
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.
   • Elton will give a walkthrough training Thursday or Friday.
3. Hot Check OUT Status 19% ready ; 61% checked ; 20% not ready
4. Installation punch list (items in red: must by Oct 15th ; 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) will be completed tomorrow. Both small walls are done. Work on iron shielding near the photon photon dump will start tomorrow.
   • Pair Spectrometer Magnet remote control - Control is now working.
   • Pair Spectrometer Magnet Field readout Done
   • 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 and won't be available for the first part of the commissioning.
   • Microscope - Microscope is in its correct position.
   • Tagger crates - Now removed from the Hall.
   • Hodoscope checks - Detectors and electronics were tested. 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 will be installed today.
   • 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.
