General Information

This document describes the run plan for the Hall D Spring 2025 run.

  1. February or March TBD: Electron beam restoration.
  2. January 24th - July 20th: 26 weeks for upgraded ECal commissioning and GlueX-II/JEF. As of 02/25/25, 9 weeks shift ⇒ March. 21st - Sept. 15th ?
  • Accelerator overall plan and priorities: Deliver physics beam to 4 halls
  • Hall D plan summary:
    • Beam and detector check-out: 50 - 300 nA. ~ a day.
      • Commission new beam profiler from Regina (Hovanes).
    • Commission of ECal (~ a month. 150 nA)
      • Opportunistic tests during possible pauses of ECAL Commissioning:
        • Diamond alignment (Hovanes, see below)
        • CDC HV scans (Beni, Naomi). Need compatible trigger
        • ToF HV scans (Beni). Need compatible trigger
        • Lead glass HV scans (Malte). Need compatible trigger
        • Study thick 80μm new diamond (Richard).
        • Others?
    • Commissioning of FCal (In parallel with ECal. Needs a commissioning plan.)
    • Diamond alignment: Stable beam (no frequent trip) 20 nA without FSD for 2-3 shifts.
    • Experiment: GlueX-II/JEF E12-12-002
    • 2 TAC runs. ~nA or less. The bleedthrough should be small compare to it. 1 run just after ECAL Commissioning. Another near the end of the run.
      • Ideally, TAC run should be done with the other Halls off.
      • If not possible, the next best option is to have both A and C not at 5 passes, so that magnetic extraction is performed (less bleedthrough than with RF separation).
        • Either Hall A or C or both are at 5 passes during the whole run ⇒ we will have to watch for opportunity when the Hall at 5 passes is down.
    • High luminosity runs: up to 1 week at 650nA, and up to 1 day at 1 uA.
    • 2 empty target runs (300 nA). 1 run at the start of GlueX-II data taking. Another near the end of the run.
    • Straight track run: 2 shifts (50% efficiency: one shift of good data) (50 nA on 10-4 R.L. radiator).
    • Opportunistic tests:
      • GEM-TRD test during ECAL Commissioning Positioned 3 to 6 o'clock in front of forward detectors, looking downstream.

Live Camera Feeds from the Four Counting Houses

  1. These feeds SHOULD be open and visible at all times from one of the monitors in each of the counting houses.
  2. Management cautions AGAINST opening them from other locations or offsite, out of concern for available bandwidth.
  • Beni will contact Walt Akers to inquire about their status. Done. Walt will take care of it.
