+ | * overall plan and priorities: | ||
+ | #The first priority is to do the Halls B and C KPP (key performance parameters). | ||
+ | #The second priority is to finish commissioning the 5-pass separator and to ensure we can reliably run with it. This is in preparation for the Fall 17 run when all halls will be a 5-pass (Hall D at 5.5 pass). | ||
+ | #*The above implies that Hall D should be run continuously at 5.5 pass and hence, the Hall D physics run is tie to priority #2. | ||
+ | #*Hall B starts its KPP run (3-pass) on Feb. 3rd. With smooth running, it should achieve the KPP goals in a day or two. Then, it shuts down. | ||
+ | #*Hall C starts its KPP run (3-pass) around March 7th. It will then continue running at 1-pass for spectrometer commissioning (if its magnets are cold and ready). Then, if time permit before the end of the spring run, they may start their physics program at 5-pass. | ||
+ | #*Hall A will be used for its beam-dump when Hall C is down, so that a high current beam can be run in the machine when Hall B and D are running. This high current beam will stabilize the beam orbit in the machine. Hall A may take advantage of receiving beam by opportunistically running its argon experiment. In that case, it will be at 1-pass. | ||

Specific instructions for connecting from JLab's Hall D conference room:
- Turn polycon on if necessary (do it before turning the computer on)
- With the polycon, place a call at 199.48.152.152
- Press # to enable the polycom keypad, then enter the meeting id: 660743227 and #
- You may have to unmute the microphone: #*4
- Turn the computer on if needed
Beam and Hall configuration
- Beam energy expected: 11.640 GeV (value from Fall 2017 measurement).
- Solenoid on at 1350A. Any field changes should be avoided if possible.
- CW Beam current:
- Range: 1 nA-1.5 μA. 250 MHz frequency.
- Standard production running expected at ~200 nA on 4·10-4 R.L. radiator.
- RSAD limit for most of the run, excluding high intensity tests: 250 nA on 4·10-4 R.L. radiator.
- FFB on or Position Slow Lock on (FFB doesn't operate below 50nA).
- Radiators:
- Goniometer diamond radiators:
- J1a50 (50 μm - 4.1·10-4 R.L., 4×4 mm²) - old crystal - excellent rocking curve
- JD70-100 (58 μm - 4.8·10-4 R.L., 7×7 mm²) - new crystal - excellent rocking curve
- JD70-105 (47 μm - 3.9·10-4 R.L., 7×7 mm²) - new crystal - good rocking curve
- JD70-104 (17 μm - 1.4·10-4 R.L., 7×7 mm²) - new crystal - wider rocking curve - marginally usable
- We also have one 10 μm Al radiator.
- 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 diamond radiators:
- Tagger quadrupole on (-4.2 A).

General Information
This document describes the run plan for the Hall D Spring 2017 run.
- Schedule for the Spring 2017 run:
- Jan. 26th-Jan. 29th: Electron beam restoration
- Jan. 30th-Mar. 22nd: Hall D Spring run.
- Every Tuesdays: 12h of beam study. Every Thursdays, if necessary: 8h of RF recovery.
- overall plan and priorities:
- The first priority is to do the Halls B and C KPP (key performance parameters).
- The second priority is to finish commissioning the 5-pass separator and to ensure we can reliably run with it. This is in preparation for the Fall 17 run when all halls will be a 5-pass (Hall D at 5.5 pass).
- The above implies that Hall D should be run continuously at 5.5 pass and hence, the Hall D physics run is tie to priority #2.
- Hall B starts its KPP run (3-pass) on Feb. 3rd. With smooth running, it should achieve the KPP goals in a day or two. Then, it shuts down.
- Hall C starts its KPP run (3-pass) around March 7th. It will then continue running at 1-pass for spectrometer commissioning (if its magnets are cold and ready). Then, if time permit before the end of the spring run, they may start their physics program at 5-pass.
- Hall A will be used for its beam-dump when Hall C is down, so that a high current beam can be run in the machine when Hall B and D are running. This high current beam will stabilize the beam orbit in the machine. Hall A may take advantage of receiving beam by opportunistically running its argon experiment. In that case, it will be at 1-pass.

Runplan
- 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 ~ 30 mrad/hr (tagger area, gammas, on goniometer).
- RAD102_P3 ~ 0.1 mrem/hr (tagger area, neutrons, near electronics racks)
- RAD508_P1 < 0.1 mrad/hr (collimator cave, gammas).
- RAD508_P2 ~ 0. mrad/hr (Hall. Neutrons).
- Typical levels are (for radiator retracted, collimator fully blocking, electron beam current 50 nA)
- Hall D tagger CARMS, Ion Chamber and BLM threshold for beam trips should not be changed without approval of Hall D leader.
- Radiator (amorphous and diamond) must be retracted. Collimator should be in blocking position.
- Establish good photon beam
- Make sure tagger quadrupole is on (-4.2 A).
- Insert 2*10-5 RL radiator. (Call MCC and ask to mask the FSD each time the radiator is moved)
- Typical levels are (for 2*10-5 radiator, electron beam current 50 nA)
- RAD102_P1= 15 mrad/hr (tagger area, gammas, between tagger and dump)
- RAD102_P2= 30 mrad/hr (tagger area, gammas, on 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 each time the radiator is moved)
- Once radiation levels are good, proceed with harp scans (Hovanes/Todd. 15 min)
- Take tagger harp scans. Check consistency with Accelerator's harps. Study beam focusing
- 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

- 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.
- Retract profiler.
- Verify with MCC that position slow lock is back on (locking on Act. Col. and for values corresponding to optimal photon flux).
