Beam and Hall configuration
- Beam energy expected:
- 11.640 GeV (same value as Fall 2016 to Fall 2018 up Nov. 15th).
- Solenoid:
- DIRC commissioning: 1350A
- PrimEx-eta run: off
- CW Beam:
- 250 MHz frequency.
- Range:
- DIRC commissioning: 1 nA-1.2 μA.
- PrimEx-eta run: 1 nA-500 nA. ??
- Chopper slit: shared with Hall A until 03/10/2019. Then alone on slit A.
- Standard current and radiators
- DIRC: Standard commissioning current: 225 nA on 1.4·10-4 R.L. radiator (JD70-104 17 μm diamond).
- DIRC: Hight intensity tests: 1.2 μA on 1.4·10-4 R.L. radiator (JD70-104 17 μm diamond) (or 0.5 μA on JD70-105, 47 μm diamond of 3.9·10-4 R.L.)
- PrimEx-eta run: Standard production on LH2: 100 nA. ?? on 30 µm Al (33.7·10-5 R.L.)
- PrimEx-eta run: Standard production on Be: 30 nA. ?? on 30 µm Al (33.7·10-5 R.L.)
- RSAD limit for most of the run, excluding high intensity tests: ?? nA on ??·10-4 R.L. radiator.
- Position Slow Lock on or FFB on (FFB doesn't operate below 50nA).
- Radiators:
- Goniometer radiators:
- Diamond JD70-104 (17 μm - 1.4·10-4 R.L., 7×7 mm²) - wider rocking curve - Tested in Spring 2018 and used at the beginning of Fall 2018. Probably has some radiation degradation.
- Diamond JD70-105 (47 μm - 3.9·10-4 R.L., 7×7 mm²) - Used for the second part of GlueX's Fall 2018 run. Good performance.
- 40 μm Al radiator (44.9·10-5 R.L.)
- V-wire (for TAC run).
- Amorphous
- 1.64 µm Al (1.86·10-5 R.L., see study)
- 10 µm Al (11.2·10-5 R.L.)
- 30 µm Al (33.7·10-5 R.L.)
- Goniometer radiators:
- Tagger quadrupole on (-4.2 A).
- Collimator hole: Both 5 mm diameter and 3.4 mm diameter. Default running: 5.0 mm.
- Targets:
- LH2 target: cryogenic target
- Be target ?? mm, ??·10-4 R.L.
- Miscellaneous:
- CPP (Charged pion polarizability) tests ??
- Transition Radiation Detector in the Hall ??
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. 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 page
- Test fast raster beam envelope measurement with larger x-rastering?
- Any other tests/plans (DAQ, Trigger, CPP, TRDS, strait track run)
- Expected Staffing and responsibilities:
- The Run Coordinator oversees the commissioning:
- Jan. 22nd-Jan. 29th, 7 days: Alexandre Deur (accelerator restoration)
- Jan. 30th-Feb. 13th, 7 days: Alexandre Deur
- Feb. 13th-Feb. 20th, 7 days: Colin Gleason
- Feb. 20th-Feb. 27th, 7 days: Sean Dobbs
- Feb. 27th-March 6th, 7 days: Justin Stevens
- March 6th-March 13th, 7 days: Alexander Austregesilo
- March 13th-March 20th, 7 days: TBD
- March 20th-March 27th, 7 days: Richard Jones
- March 27th-Apr. 3rd, 7 days: TBD
- Apr. 3rd-Apr. 7th, 4 days: TBD
- The Physics Division Liaison (PDL) and Hall D Work Coordinator/Safety Warden (M. Stevens) verify that the proper safety rules are followed. PDL is:
- Lubomir Penchev
- The analysis coordinator (Alexander Austregesilo) oversees the off-line diagnostic of the different systems and analysis of the data.
- Shifts: 2 persons per shift.
- The Run Coordinator oversees the commissioning:
- Coordination Activities:
- The RC will attend the MCC meetings at 7:45am and 8:00am and the weekly MCC meeting (Wednesday, 1:30pm). The PDL will attend the weekly MCC meeting.
- Daily run meetings broadcasted on Bluejeans will occur at 8:45am in the counting house conference room. The Run Coordinator will be responsible for organizing and chairing the meeting.
- Useful links:
- Accelerator schedule
- Link to Richard Jones program to plot the beam profile at the collimator.
- Links to previous runplans
- Links to beam parameters/radiation level monitoring:
- Last 8-hours plots showing 1-minute, 10-minute, and hourly averages
- Same but Last 24-hours
- Same but Last 72-hours
- Week, month, and quarter (3 months) plots also exist, with similar web addresses.
