  • With the polycon, place a call at
  • Press # to enable the polycom keypad, then enter the meeting id: 660743227 and #
  • You may have to unmute the microphone: #*4
  • Turn the computer on if needed

Beam and Hall configuration

  • Beam energy expected: 11.632 GeV (include synchrotron radiation losses, except for the Hall D ramp).
  • Solenoid on at 1350A ? Do we want to gather some data at different fields?). Any field changes should be avoided if possible.
  • Beam current: CW 5 nA-1.5 μA. 250 MHz frequency. Entire run at same RF?
  • Position slow lock on or FFB on? Current and energy locks on?)
  • Radiators:
    • Goniometer diamond radiators: TBD. We presently have test diamonds:
      • (J1a50 (50 μm, 4.1·10-4 R.L.)),
      • J2a100 (100 μm 8.2·10-4 R.L.),
      • S145-S90 (90 μm, 7.4·10-4 R.L.) and
      • JD70-3 (80 μm, 6.6·10-4 R.L.))
      • We also have 3 test foils (two 10 μm Al foils, and one 100 μm Al foil with a holed 10 μm Al foil pressed on it (3mm hole)).
    • We expect to have four additional diamonds, all 7mm by 7mm
      • 20 micron
      • 20 micron
      • 50 micron
      • 50 micron
    • Amorphous
      • 1.5 µm Al (1.7·10-5 R.L.)
      • 10 µm Al (11.2·10-5 R.L.)
      • 30 µm Al (33.7·10-5 R.L.)
  • Collimator hole: Both 5 mm diameter and 3.4 mm diameter. Default running: 3.4 mm?

General Information

This document describes the run plan for the Hall D Spring 2016 run.

  • Schedule for the Spring 2016 run. (Dates are according to the long term calendar.)
    1. Oct. 1st-Oct. 7th: Electron beam restoration
    2. Oct. 8th-Nov. 22nd: Hall D Fall run, part 1.
    3. Nov. 23rd-Nov. 27th: Thanksgiving break.
    4. Nov. 28th-Dec. 18th: Hall D Fall run, part 2 (includes 2 day of beam restoration).
    5. Dec. 19th-Dec. 21st: TBD
    6. Every Tuesdays: 12h of beam study. Every Thursdays, if necessary: 8h of RF recovery.
  • Goals for the Fall 2016 run.
  1. GlueX low luminosity data taking
  2. High luminosity trigger and DAQ tests.
  3. ToF checkout.
  • Expected Staffing and responsibilities:
    • The Run Coordinator oversees the commissioning.
      • Oct. 1st-Oct. 7th A. Deur
      • Sat. Oct. 8th - Wed. Oct. 19th: A. Deur
      • Wed. Oct. 19th - Wed. Nov. 2nd: M. Dalton
      • Wed. Nov. 2nd - Wed. Nov. 16th TBD
      • Wed. Nov. 16th - Mon. Nov. 22ndTBD
      • Sun. Nov. 27th - Wed. Dec. 7thTBD
      • Wed. Dec. 7th - Sun. Dec. 18th TBD
      • Mon. Dec. 19th - Wed. Dec. 21st If RC necessary, TBD
    • The Physics Division Liaison (PDL, Benedikt Zihlmann) and Hall D Work Coordinator/Safety Warden (T. Carstens) verify that the proper safety rules are followed.
    • Shifts: 2 persons per shift.
  • Coordination Activities:
    • The RC will attend the MCC meetings at 7:45am and 8:00am and the weekly MCC meeting (Wednesday, 1:30pm). The PDL will attend the weekly MCC meeting.
    • Daily run meetings broadcasted on Bluejeans will occur at 8:45am in the counting house conference room. The Run Coordinator will be responsible for organizing and chairing the meeting.
  • Useful links:


  1. Re-establish electron and photon beams (assume 3 days).
  1. Detector and beamline checkout.
    • ToF tests (Benedikt Zihlmann).
  2. Realign old diamonds. Align new Diamonds. (Hovanes, Paul Mattione, Ken Livingston?).
  • Systematic studies needed? e.g. run a different coherent peak position?)
  1. L1 trigger test for high-rate performance tests (Alex Somov. 8h+8h. Use up to 1 μA. DC off if necessary)
  • Check rates for various beam currents and thr. settings.
  1. L3 high-rate performance tests (David Lawrence)
  2. DAQ high-rate performance tests (Sergei Furletov)
  3. Gluex data production
  4. *quadrupole off?)
  • Empty target run every ?? (5h: 1h to empty/fill back the target, 2h running)). Standard production current or highest possible or both? )
  • Amorphous run Every day? 1h? Standard production current?). Time to switch from pol. to unpol.: 10min. time to switch from unpol. to pol.: 30min.
  • TAC runs every ?? )(Hovanes, Alex Somov, 2h? :1^+ h run, 1^- h target empty+fill))
  • Physics production data with diamonds and 5 mm hole. Ratio of para./transverse data:50/50. 1h runs? Switch every 2 runs. Time to switch: 10min.
