- Completed Q2=2.45 W=3.2, middle epsilon, SHMS center
- Started Q2=2.45 W=3.2, middle epsilon, SHMS left (achieved about 3/4 of reduced statistics goal) - VBV3H08 (big valve downstream of target) closed and would not open.
Current Run Plan
- Wait for beamline valve fix
- Rotate SHMS to 5.5 degrees
- Continue with Q2=2.45 W=3.2, middle epsilon, SHMS right
- Move on to Q2=3.85, W=3.07, low epsilon: SHMS right, center, left
- Note: when rotating away from 5.5 degrees after SHMS right setting, will have to contact Steve Lassiter or Amy Comer to enable rotation
- Have MCC perform arc energy measurement when convenient (sooner is better)
- Beam off at 6:30 tomorrow for maintenance day
Notices in Effect for Shift Crew
- If all SHMS magnets crash at the same time, push the SHMS dipole crash button (on the rack above the target heater manual controls and target temperature readbacks).
- See Jacob's log entry about physics plotting script: https://logbooks.jlab.org/entry/4026914
Current Issues
- Downstream beamline valve
- Coffee maker broken! Emergency instant coffee in Counting House.
- Shifts filled until August 14 - then we have OWL shifts available up to August 19. Lots of openings August 20++.
Planned Accesses to the Hall
- Access today for valve repair and SHMS rotation
- Maintenance day still scheduled for Thursday - Controlled Access planned
- Aerogel change: if all goes extremely well, aerogel change could happen Friday. Otherwise, will take place Monday.
Planned Accelerator Configuration Changes
- Pass change (4->3) next week. Right now, on the white board for Tuesday, August 16
Special Requests
- Fix coffee machine, or replace.
