- Nominally, every Mondays: 12h of beam study. Every Tuesdays, if necessary: 8h of RF recovery.
- Accelerator overall plan and priorities:

- 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)

- 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.
