Live Camera Feeds from the Four Counting Houses
- These feeds SHOULD be open and visible at all times from one of the monitors in each of the counting houses.
- Management cautions AGAINST opening them from other locations or offsite, out of concern for available bandwidth.
Setting Up Photon Beam
- Verify electron beam quality and establish photon beam
- Ion Chambers trip threshold must be set using diamond JD70-105 as well as the 4 Al. radiators (1 on goni, 3 on amorphous radiator ladder)
- 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 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).
- Typical levels are (for radiator retracted, collimator fully blocking, electron beam current 50 nA)
- Radiator (amorphous and diamond) must be retracted. Collimator should be in blocking position.
- 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= ~ 50 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 (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, collimator at 5mm):
- 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. There is need to run the DAQ or stop the beam between each steps: the data are recorded by EPICS. However, the beam need to be off when moving to a different radiator for the next steps.
- 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. 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.
