General Information
This document describes the run plan for the Hall D Fall 2018 run.
- Schedule for the run:
- Jan. 22nd - 29th: Electron beam restoration
- Jan. 30th - Feb. 12th: 2-weeks DIRC Commissioning (Solenoid at nominal field. LH2 target)
- Feb. 12th - Apr. 7th: 8.5-weeks PrimEx-eta run (Solenoid off. Be then LH2 target ??).
- 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. 11th. 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 page)
- Test fast raster beam envelope measurement with larger x-rastering. Need detailed plan, including time estimate
- Any other tests/plans (DAQ, Trigger, CPP, TRDS, strait track run)

- Week, month, and quarter (3 months) plots also exist, with similar web addresses.
- A map of the radiation monitors
Runplan
- 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 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).
- Typical levels are (for 2×10-5 radiator, electron beam current 50 nA)
- Insert 2*10-5 RL radiator. Call MCC and ask to mask the FSD and turn off beam each time a radiator is moved
- Verify beam position and envelope.
- 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
- PS detector threshold scan. (A. Somov, 1h)
- Microscope yield study (row-by-row scan). (Richard/Jim McIntyre, 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.
- 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.
- Detector and beamline checkout.
- 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).
- Long mode (Mode 10) w/ FCAL LED on 1-10Khz (Mark D.)
- Run 15 min (solid time) in Production Mode (Mode 9).
- CDC HV scan Procedure to follow (Naomi Jarvis, 4h)
- High beam current systematic test (8h. Can be done before or after diamond alignment, as most convenient for the alignment)
- Insert 10 μm Al. radiator (1.12*10-4 RL, on amorphous rad. ladder). Take 200M events (standard prod.) at 680 nA beam current. Monitor carefully rates in wire chambers.
- Insert 40 μm Al. radiator (4.49*10-4 RL, on goni.). Take 200M events (standard prod.) at 170 nA beam current. Monitor carefully rates in wire chambers.
- Align 17 μm diamond (JD70-104) for the 4 polarization configurations (Hovanes. 16h).
- Gluex data production
- Physics production data with 17 μm diamond, 530 nA, 5 mm hole, 75 μm TPol convertor. Ratio of para./transverse/45o/135o data:25/25/25/25. 300M events per configuration. 2h runs and no more, as it may be hard to correct for calibration drifts. Switch polarization every 300M events. Time to switch: 10min. DAQ start run overhead: 3min.
- Amorphous run. Every set of 4 diam. orientation runs. 150M events. 170 nA on 40 μm Al. radiator (4.49*10-4 RL, on goni.). Time to switch from pol. to unpol.: 10min. time to switch from unpol. to pol.: 30min.
- Log in run information in the shift summary (make a run list). For each production run, log useful comments on DAQ comment window, see [3]
- Tagger quadrupole on
- Harp scans once a day: 15 min.
- If commissioning and analysis are successful, once a day, a beam envelope measurement by rastering on Act. Col. ??min
- Empty target run every 2 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).
- Align JD70-105 (47 μm - 3.9·10-4 R.L., 7×7 mm²) for 2 or 4? polarization configurations (Hovanes 12h) and take enough data to achieve ~1% statistic on rho polarimetry (8h at 190 nA). Decide if it is better to run on this diamond.
- Two TAC runs at the beginning and end of 11.6 GeV run. May require other halls to be off due to bleedthrough (Hovanes, Alex Somov 8/h run.)
- Luminosity scans (J. Stevens)?
- Some physics production data with thin diamond and 3.4 mm hole 11h (1 cycles of runs). More data may be taken if beam stability and assessed polarization warranty it.
- ToF runs for muon chamber? Need solid target. Need detailed plan, including time estimate
- Parasitic TRD run
- During 10.2 GeV and 9.0 runs:
- Re-establish good photon beam. Ion Chamber thresholds to be set each time electron beam energy changes.
- Set PS field to rescaled value?
