Specific instructions for connecting from JLab's Hall D conference room:
- Turn polycon on if necessary (do it before turning the computer on)
- With the polycon, place a call at 199.48.152.152
- 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:
- 11.55 GeV
- Solenoid:
- 1350A
- CW Beam:
- 250 MHz frequency.
- Range: 1 nA-900
- Chopper slit: TBD (assume C, since Hall C will be at 5-pass all the time)
- Standard current and radiators
- ~350 nA on a 4.1·10-4 R.L. radiator (50 μm diamond). (RSAD limit 500nA on 58 μm diamond)) Is this still valid?
- ~350 nA on a 33.7·10-5 R.L. AL radiator (30 µm Al). (RSAD limit 600nA on 30 µm Al radiator))
- Position Slow Lock on or FFB on (FFB doesn't operate below 50nA).
- Radiators:
- Goniometer radiators:
- Diamond TBD
- Amorphous 40 μm Al radiator (44.9·10-5 R.L.)
- V-wire (for TAC run).
- Amorphous
- 1.64 µm Al (1.86·10-5 R.L., see study)
- 10 µm Al (11.2·10-5 R.L.)
- 30 µm Al (33.7·10-5 R.L.)
- Goniometer radiators:
- Tagger quadrupole on (-4.2 A).
- Collimator hole: Default running: 5.0 mm.
- Targets:
- LH2 target: cryogenic target
- PS converter: 75 μm
- Miscellaneous:
- PS test area: TBD
- Other?
General Information
This document describes the run plan for the Hall D Spring 2023 run.
- Schedule for the run (see July 2022-March 2024 official schedule):
- January 5th -12th: Electron beam restoration.
- January 12th - March 20th: 10 weeks for GlueX high luminosity production.
- Accelerator overall plan and priorities: Deliver physics beam to 4 halls
- Hall A, always at 4-pass, is scheduled stop early, on March. 13th.
- Halls B and or C will always be at 5-pass
- Hall D plan Tentative guess
- Experiment: GlueX-II E12-12-002
- One (?) TAC run.
- Two (?) empty target runs (One at the start of the run, the other consecutive to TAC run)
- Straight track run (?)
- Overall, one night of good data.
- Opportunistic tests?
- Expected Staffing and responsibilities:
- The Run Coordinator oversees the run:
- January 12 - 18, 6 days: Joerg Reinhold
- January 18 - 27, 7 days: Alexandre Deur
- January 27 - Feb. 1st, 7 days: Edmundo Barriga
- Feb. 1st - 8th: 7 days: Beni Zihlmann
- Feb. 8th - 15th: 7 days: Igal Jaegle
- Feb. 15th - 22nd: 7 days: TBD

- March 1st - March 8th: 7 days: Tolga Erbora
- March 8th - March 15th: 7 days: Churamani Paudel
- March 15th - March 20th: 5 days: Richard Jones
- The Run Coordinator oversees the run:
- The Physics Division Liaison (PDL) and Hall D Work Coordinator/Safety Warden (S. Spiegel) verify that the proper safety rules are followed. PDL is:
- PDL: B. Zihlmann
- The analysis coordinator (Alexander Austregesilo) oversees the off-line diagnostic of the different systems and analysis of the data.
- Shifts: 2 person shifts: 1 local leader and 1 (optionally remote) worker scheduled through the GlueX shift scheduler.
- The Physics Division Liaison (PDL) and Hall D Work Coordinator/Safety Warden (S. Spiegel) verify that the proper safety rules are followed. PDL is:
