 +
**Tagger hodoscope (A. Somov)
 +
***Was powered and checked last week. Looks good. <strike>A bad FADC was found. Fast electronic group looked at it and it is now replaced (11/28).</strike>
 +
***There are also a few suspicious channels:
 +
****Found two dead  channels (11/28). They belong to the low energy end of the γ-spectrum, so they are not the most important ones.

***In place. Scalers are counting.</strike>
 +
**FDC (Lubomir)
 +
***<strike>Two of the mainframes are misbehaving.</strike>
 +
***Minor issues with some LV channels: About once a week, they stop being regulated. An alarm is implemented to signal this. It can be fixed by just pressing a button (instruction is provided with the alarm). This problem seems to be gone now (have not occurred for several weeks).
 +
***<strike>On but controls are not working yet. Controls are now working. Some mis-cabling found. Will be patched by relabeling the cables.
 +

 +
**TOF (Mark Ito/Beni/Alex. Ostrovidov)
 +
***<strike>HCO done.
 +
***Communication problem with HV crates. 1 HV module was broken. Have to turn TOF on to see if it is fine now. Now fixed.

*muon chamber  (Elton S.)
 +
**Presently (11/02) in the EEL building and being tested there. Looking fine.
 +
**<strike>The wires were drawing more current than expected but this is gone. This problem was due to humidity. A dehumidifier paste was added.

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 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).
      • Hall D tagger CARMS, Ion Chamber and BLM threshold for beam trips should not be changed without approval of Hall D leader.
    • 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 n 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 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.
      • 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
    • Microscope yield study (row-by-row scan). (Richard/Jim McIntyre/Alex Barnes, 1h)
      • 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.
    • 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.
  3. Realign 60 μm diamond (JD70-100) for the 4 polarization configuration (Hovanes, Paul Mattione. 16h/diamond).
  4. Beam background measurements for PRad target TAC runs. (A. Deur/Hovanes/A. Somov) 10-250nA, no radiator, TAC in, target full. 1h. Several runs throughout Fall/Spring run periods.
  5. Straight track run (16h, nominally at the end of the Fall run. Otherwise, end of Spring run) (Lubomir)
    • Ramp down solenoid magnet (8h)
    • Take straight track run data (Lubomir)
  6. Gluex data production
    • 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 scans once a day: 15 min.
    • If commissioning and analysis were successful, once a day (?), a beam envelope measurement by rastering on Act. Col. ??min
    • Empty target run every 3 week (2h: 1- h to empty/fill back the target, 1h running). Standard production current.
    • 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.
    • TAC commissioning, systematic studies and runs. (Hovanes, Alex Somov 2 days.)
      • V-wire commissioning.
      • Move around the collimator with 1mm plug to see effect on TAC. Do 4 different positions.
      • Check effect of material on γ-beam path on TAC: for ex. fill the target (30 min to fill or empty target).
      • Do a TAC run without solenoid field to test GEANT TAC simulation in simpler conditions. (To be done around straight-track runs).
    • Physics production data with diamonds and 5 mm hole. Ratio of para./transverse/45o/135o data:25/25/25/25. 2h runs and no more, as it may be hard to correct for calibration drifts. Switch polarization every run. Time to switch: 10min. DAQ start run overhead: 3min.
      • Luminosity:
        • Run at about 200 nA (for 60 μm diamond JD70-100).
  7. Parasitic muon chamber
  8. Parasitic TRD run
  9. List of tasks to be done without solenoid field
