Short Optics Plan
Define the following jobs:
A. Acceptance calib, sieve out, raster on and off (large C12, no LHe) B. Delta scan, (sieve in, C12, no LHe) C. Beam persion scan (Sieve in, large C12, no LHe, 8 points on x,y axis and 4 additional points at corner) D. Pointing (Sieve in, CH2, need refill LHe)
Here is the summary of all optics
1. 0T @ 2.257:
Do A, move sieve in, do B and C(12 points), refill LHe do D. At the end take elastic NH3 data to check NH3 thickness. When finish: move sieve out; Ramp field up to 2.5T; Drian LHe
2. 2.5T, 90deg @ 2.257:
Do A, move sieve in, do B and C(12 points), refill LHe do D When finish: Ramp field up to 2.5T; Drian LHe out
3. 5.01T, 6deg @ 2.257:
Do B and C(8 points), refill LHe do D.
4. 2.5T, 90deg @ 1.706:
Do A, move sieve in, do B and C(8 points), refill LHe do D When finish: Rotate target field to 6 deg; Ramp up to 5.01T; Drian LHe out
5. 5.01T, 6deg @ 1.706:
Do B and C(8 points), refill LHe do D When finish: Move sieve out; Rotate target field to 90 deg; Ramp up to 5.01T; Drain LHe out
6. 5.01T, 90deg @ 2.257:
Do A, move sieve in, do B and C(8 points), refill LHe do D When finish: Turn off target field; Drian LHe, move sieve out.
7. 0T @ 1.159:
Do A, move sieve in, do B and C(8 points), refill LHe do D. At the end take elastic NH3 data to check NH3 thickness. When finish: move sieve out; Ramp field up to 2.5T; Drian LHe out
8. 2.5T, 90deg @ 1.159:
Do A, move sieve in, do B and C(8 points), refill LHe do D When finish: Ramp field up to 5.01T; Drian LHe out
9. 5.01T, 6deg @ 1.159:
Do B and C(8 points), refill LHe do D
For commissioning:
