Runplan

  1. Verify electron beam quality and establish photon beam (assume 1 day).
    • Ion Chambers trip threshold must be set using diamond JD70-105 as well as the 4 Al. radiators (1 on goni, 3 on amorphous radiator ladder)
    • Tune electron beam with radiator retracted
      • Radiator (amorphous and diamond) must be retracted. Collimator should be in blocking position.
        • Typical levels are (for radiator retracted, collimator fully blocking, electron beam current 50 nA)
          • RAD102_P1 ~ 10 mrad/hr (tagger area, gammas, between tagger and dump)
          • RAD102_P2 ~30 mrad/hr (tagger area, gammas, on the ground below the goniometer).
          • RAD102_P3 ~ 0.3 mrem/hr (tagger area, neutrons, near electronics racks)
          • RAD508_P1 < 0.1 mrad/hr (collimator cave, gammas).
          • RAD508_P2 ~ 0. mrad/hr (Hall. Neutrons).
    • Establish good photon beam
    • Make sure tagger quadrupole is on and at -4.2 A. (It can be turned on only once the Hall is in power/beam permit.)
      • Insert 2*10-5 RL radiator. Call MCC and ask to mask the FSD and turn off beam each time a radiator is moved
        • Typical levels are (for 2×10-5 radiator, electron beam current 50 nA)
          • RAD102_P1= 35 mrad/hr (tagger area, gammas, between tagger and dump)
          • RAD102_P2= ~ 50 mrad/hr (tagger area, gammas, on the ground below the goniometer)
          • RAD102_P3= ~2 mrem/hr (tagger area, neutrons, near electronics racks)
          • RAD508_P1= ~10 mrad/hr (collimator cave, gammas).
          • RAD508_P2 < ~ 0. mrad/hr (Hall. Neutrons).
    • Verify beam position and envelope (Hovanes).
      • Ask MCC to set beam position on 5C11b to x=-0.5 mm and y=+1.0 mm.
      • Ask MCC for 5C11 and 5C11B HARP. Then do our radiator HARP scan, see instruction. If it looks good, proceed to next step. Otherwise, inform MCC.
      • Insert profiler (no need for masking FSD when an object is inserted in the photon line), run with 10×10-4 radiator and 50 nA. Beam on the profiler should be at x=0.0±0.5cm; y=0.0±0.5cm. If not, inform MCC.
    • Radiation level study (1h):
      • Run 5 min without radiator (Call MCC and ask to mask the FSD each time the radiator is moved). Beam current: 50nA. Repeat at 100 nA and 200 nA. There is need to run the DAQ or stop the beam between each steps: the data are recorded by EPICS. However, the beam need to be off when moving to a different radiator for the next steps.
      • Run 5 min with the 10-4 radiator (Call MCC). Beam current: 50nA. Repeat at 100 nA and 200 nA
      • Run 3 min with the 3*10-4 radiator (Call MCC). Beam current: 50nA. Repeat at 100 nA and 200 nA
    • Photon flux optimization and Active Collimator calibration. (20 + 20 mins). Call Hovanes.
      • re-Insert the 10-4 radiator (Call MCC). Use about 100 nA beam current. This will provide the Act. Col. nominal positions for its high gain values.
      • Determine maximum photon beam transmission by doing 2D scans using the collimator x/y motions (Hovanes. 1h)
      • Repeat procedure with 2*10-5 radiator (Call MCC) and 50 nA beam current. This will provide the Act. Col. nominal positions for its low gain values.
      • Record on the white board what is the beam position on 5C11b and Active Collimator for optimal photon transmission, both for low and high Act. Col. gain.
      • Until Hovanes determines to optimal 5C11b and Active Collimator position, keep profiler in and beam locked (MCC's duty) on the nominal 5C11b and x=0,y=0 profiler position. Once Active Collimator nominal beam position is known, retract profiler and lock the beam (MCC) on the active collimator.
  2. Detector and beamline checkout.
    • Any time before starting production (beam quality is not important): microscope HV scan (2h, R. Jones)
    • Reestablish L1 trigger (Alex. Somov. 2h).
    • PS and TAGH HV scan. (Alex. Somov. 1h).
    • Reestablish DAQ (Sergei, 2h).
    • General detector calibration (Sean Dobbs. (703-887-1776) 1h). Use 2×10-5 Al. radiator. Beam current 200nA (Solenoid magnet is off)
      • Run 15 min (solid time) in Long Mode (Mode 10)
      • Run 15 min (solid time) in Production Mode (Mode 9).
  3. CDC HV scans (Naomi 6h). Use 4.5×10-4 Al. radiator (on goni). Beam current 360nA
  4. 47 μm diamond (Start on JD70-105) alignement check. Later during the run, align new JD70-103 (4 polarization configurations) (Hovanes. 2h ).
  5. GlueX-II pre-production (20h)
    • Identical as production below, but at 150 nA. One cycle of five 2h runs on 4 polarization configurations+1 amorphous.
  6. GlueX-II production
    • Standard configuration: 47 μm diamond, 350 nA, 5 mm hole, TPol on 75 μm TPol convertor. 2h runs and no more, as it may be hard to correct for calibration drifts. Cycle over 5 sets of runs: 0o, then 90o, then 45o, then 135o, then amorphous runs.
      • Amorphous runs: 4.5×10-4 Al. radiator (on goni). 350 nA
    • Log in run information in the shift summary (make a run list). For each production run, log useful comments on DAQ comment window, see [2]
    • Tagger quadrupole on
    • Harp scan (30 min): Every 2 days
    • 2 Empty target run (2h: 1- h to empty/fill back the target, 1h running). Standard production current. After TAC run, beam study or RF recovery.
  7. One "TAC" run + test of new FCal divider.
    • a few nA, thinest Al. radiator and ComCal.
    • To be coordinated with MCC.
    • Measure bleedthrough. If acceptable, (~nA or less), proceed with TAC-ComCal run. Otherwise, explore possibility for invasive TAC run.
    • If commissioning and analysis are successful, once a day (?), a beam envelope measurement by rastering on Act. Col. ??min
    • Long mode 10 min run. Once a week (20 min).
    • Amorphous run. Every set of 4 diam. orientation runs. 1h Standard production current. Time to switch from pol. to unpol.: 10min. time to switch from unpol. to pol.: 30min.
    • Synchronize TAC run with test of new FCal divider (A. Somov).
  8. Trigger test for the SRC experiment (A. Somov, 6 hours)
  9. CPP trigger test (??34h??). (https://halldweb.jlab.org/wiki/index.php/CPP_Test_2020_-_Schedule discussion on tentative plan]) Could be done during pass change for Hall C on Sept. 4th. There will be 2-3 days of running left depending on how smooth the pass change goes. If so, we likely need other tests to use the left beam time (We could do the TAC run then/Empty target run/...?)
