Current Status
- Jack, Ethan, Steve and Joe working on HMS Q2.
- Coincidence DAQ currently taking cosmics.
- Many angle changes last night, no need to reset rotation controller...also no radiator. Techs installed Pb bags near controller box: logbook post
- Summary of runs from last night:
1) x>1 optics study, Ep = -7.001, theta = 13.11 deg, normal tune: run 7170
2) x>1 optics study, Ep = -7.001, theta = 13.11 deg, F2 tune: run 7171
3) F2 yptar scan, Ep = -3.3 GeV, theta = 21 deg, normal tune: run 7172
4) F2 yptar scan, Ep = -3.3 GeV with theta = 19.85 deg, 21 deg, 22.15 deg, F2 tune: runs 7173@21deg, 7174@19.84deg, 7175@22.14deg
5) F2 positron run plan, 38 deg , Ep = +1.8 GeV: LH2 runs=7176, 7182; LD2 runs=7177, 7178, 7179; Al runs=7180, 7181
Current Run Plan
- x>1 (11/14 hours = 39% of experiment total)
- x>1 in 14 hours
- F2 positron run plan:
- Keep ELCLEAN rate <5 kHz
- TO will need to adjust the cryo load between LH2 and LD2!
- Use the F2 tune to set the magnets: go_magnets_SHMS_F2
1) 33 deg, Ep = +1.7 GeV , ELCLEAN statistics = 10k e+ on each target: LH2, LD2, Al dummy (half stat Al)
2) 33 deg, Ep = +2.6 GeV , ELCLEAN statistics = 8k e+ on each cryo target: LH2, LD2, Al dummy (half stat Al)
3) 25 deg, Ep = + 3 GeV, ELCLEAN statistics = 3k e+ on each cryo target: LH2, LD2, Al dummy (half stat Al)
3) 25 deg, Ep = - 3 GeV, ELCLEAN statistics = 3k e- on each cryo target: LH2, LD2, Al dummy (half stat Al)
- If there is time, take more statistics!
- Sylvester's negative half of J/psi [1]
--> run at the last block of kinematics under "Setting scan" - 15 min per kinematic setting
Notices in Effect for Shift Crew
- If rotation cannot be Reset, call the RC, then call Ops for an escorted/controlled access.
