General Information
This document describes the run plan for the Hall D Fall 2019-Spring 2020 run.
- Schedule for the run:
- Nov. 18th - 24th: Electron beam restoration.
- Nov. 25th - Dec. 19th: 2 PAC-weeks for DIRC Commissioning (Solenoid at nominal field. LH2 target))
- Dec. 20th -Jan. 2nd: Xmas break.
- Jan. 3rd - 9th: Electron beam restoration. (Same condition as Fall ⇒ It is not unreasonable to imagine it to be faster))
- Counting room should be staffed.
- If time allows, the GEM/TRD will be moved to PS location (lower priority than GlueX production if we have an early start).
- Jan. 10th -May 6th: GlueX high luminosity production.
- Nominally, every Mondays: 12h of beam study. Every Tuesdays, if necessary: 8h of RF recovery.
- Accelerator overall plan and priorities:
- Deliver physics beam to 4 halls. (Hall A stop early, on March. 23rd. Halls B and or C will always be at 5th pass (except for 2×2 days for Hall C), so Hall D beam will always be RF-separated.)
- Experiment: GlueX E12-06-102 Production
- Straight track run at the very beginning of the Fall run: one night of good data ⇒ overall one calendar day including solenoid ramp-up.
- DIRC commissioning page (+TRD/GEM).
- DAQ:
- new CODA 4h at higher intensity than standard.
- cDAQ 4h at higher intensity than standard.
- Data consistency check (parasitic).
- Trigger tests:
- FCal-BCal-ST trigger test: 1 shift
- High intensity (i.e. nominal for this run) trigger needs tuning at each increase of the beam current until nominal high intensity is reached.
- HV scans for TOF's new counters.
- Tagging accidentals beam tests (Richard Jones, Beni) ??h invasive)
- ComCal test: anode current studies with special trigger (raw mode): 1h invasiv.
- Pair. Spec. test area:
- Right arm (facing downstream): FCal Pb-W cristal quality and detector checks. Fully parasitic
- Left arm: Test of Hall C 3×3 block glass-scintillator prototype. During Spring 2020: TRD/GEM will be present after removal from in front of DIRC. Aerogel may be present. Fully parasitic
- EIC GEM test? (left arm?)
- CPP trigger tests: 1 shift + 2 shifts of installation/removal.
- Invasive.
- Installation/removal should be coordinated with beam study and RF recovery, to save a shift or two.
- Test fast raster beam envelope measurement with larger x-rastering (Richard Jones) ??h invasive)
- Beamline, FCal platform: Fiber test for profiler prototype (Regina)?

- The Physics Division Liaison (PDL) and Hall D Work Coordinator/Safety Warden (M. Stevens) verify that the proper safety rules are followed. PDL is:
- Benedikt Zihlmann
- The analysis coordinator (Alexander Austregesilo??)) oversees the off-line diagnostic of the different systems and analysis of the data.
- Shifts: 2 persons per shift.
- The Run Coordinator oversees the run:
- 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.
