  1. Nominally, every Mondays: 12h of beam study. Every Tuesdays, if necessary: 8h of RF recovery.
  • Accelerator overall plan and priorities:
  1. Deliver physics beam to 4 halls. (Hall A stop early, on March. 10th. Halls B and or C will always be at 5th pass, so Hall D beam will always be RF-separated.)
  • DIRC commissioning page
  • PrimeX run plan
  • DAQ and Trigger high-intensity tests during DIRC commissioning.
  • CPP tests during last day of DIRC commissioning.
  • Parasitic TRD runs.
  • If opportunity arises, test fast raster beam envelope measurement with larger x-rastering (Richard Jones)
  • Strait track runs not expected to be needed

Runplan

  1. Verify electron beam quality and establish photon beam (assume 1 day).
    • Ion Chambers trip threshold must be set using Al. radiators
    • 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 < 0.1 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= < 0.5 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
      • 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.
    • PS detector threshold scan. (A. Somov, 1h) Can be done early if necessary: nominal beam quality not mandatory.
    • Microscope yield study (row-by-row scan). (Richard Jones/Jim McIntyre, 1h) Can be done early if necessary: nominal beam quality not mandatory.
      • Call Richard Jones 20 min before the start of this task. Call Alex Somov to set-up the PS trigger.
      • Insert 5mm collimator.
      • Procedure to follow
      • Any type of beam quality will do.
      • 10-4 radiator, 10-3 convertor, 80 nA beam current.
    • Reestablish L1 trigger Alex. Somov. 2h).
    • Reestablish DAQ (Sergei, 2h).
    • General detector calibration (Sean Dobbs. 1h). Use 10-4 radiator.
      • Run 15 min (solid time) in Long Mode (Mode 10)
      • Run 15 min (solid time) in Production Mode (Mode 9).
  3. Check 17 μm diamond (JD70-104) alignement. (We expect to use 2 polarization configuration only) (Hovanes. 1h).
  4. DIRC commissioning
    • DIRC commissioning page
    • Standard configuration: 17 μm diamond, 225 nA (1.2 μA for high intensity run), 5 mm hole, TPol on (for TPol syst. studies. Not necessary for DIRC) 75 μm TPol convertor??. 2h runs and no more, as it may be hard to correct for calibration drifts. Cycle over 3 sets of runs: ∣∣, then ⊥, then amorphous runs (i.e. two diamond settings only). DAQ start run overhead: 3min.
    • Luminosity scans on amorphous radiator. 50-300 nA. Use 10 µm Al (1.12·10-4 R.L.), on amorphous radiator ladder.
    • Tagger quadrupole on
    • Harp scan (30 min): Only once in the middle of the DIRC commissioning (beside the ones done during beam set-up).
    • One Empty target run (2h: 1- h to empty/fill back the target, 1h running). Standard production current.
    • Long mode 10 min run. Twice or Thrice a week. Beam must be off. On opportunistic basis if possible (Purpose: monitor neutron radiation damage to ST due to nuclear target higher neutron yield.)
    • No TAC run necessary
  5. Transition to PrimEx-η
    • CPP (Charged pion polarizability) tests (Not firm yet.)
      • To be set-up and done during the last day of DIRC allocated commissioning time.
      • Use LH2 target, keep solenoid on at nominal field, DIRC stays in nominal position.
      • Move downstream platform downstream
      • Install passive shielding in front of TOF.
      • Set-up and check specific CPP trigger: 2h (Alex Somov).
      • Tests (to be done for various thicknesses of passive shielding).
      • End of test: ramp down solenoid, remove shielding.
  6. PrimEx-η
    • PrimEx-η runplan page
    • Standard configuration: 10 µm Al (11.2·10-5 R.L. Beam current depends on target. 2h runs and no more, as it may be hard to correct for calibration drifts</font>. DAQ start run overhead: 3min.
    • Two TAC runs (to be done with the TAC detector, not with ComCal).
      • First one: shortly after March 10th, once we Hall A is down and we run on the Hall A slit.
      • Second one: near the end of the run.
      • HARP scan (only Hall D harp): 10 min. Every two days.
    • Long mode 10 min run. Twice or Thrice a week. Beam must be off. On opportunistic basis if possible (Purpose: monitor neutron radiation damage to ST due to nuclear target higher neutron yield.)
