Run plan Monday-day shift → Wednesday owl

Tentative runplan for Monday-day shift → Wednesday owl

During that time the beam will not be longitudinally polarized.

1. Monday Day-Swing:
   • Target change: 8h
   • Polarimetry calibrations: 8h
   • Meanwhile, top-off the He3 ref cell pressure to 8 atm? (We currently (Thursday) have 65 PSIA left in the Ref. Cell, but it is slowly leaking out)
2. Monday Owl: ref cell runs. See here for the ref. cell runs on original run plan
   • 3 hours of Ref. Cell 3He runs at 3.4 GeV. (1.5h of solid beam time, 3h assuming 50% efficiency.)
   • Change momentum settings to 2.6 GeV (30 min)
   • 2h of Ref. Cell 3He runs at 2.6 GeV. (1h of solid beam time, 2h assuming 50% efficiency.)
   • Empty Ref. cell.
   • 3h of empty Ref. Cell 3He runs at 2.6 GeV. (1.5h of solid beam time, 2h assuming 50% efficiency.)
3. Tuesday Day: continue Ref. cell and do positron runs.
   • Finish whatever is left of the 3h of empty ref cell run. (assume 1h)
   • Fill ref cell with N2 at 10 atm.
   • 1.3h of Ref. Cell N2 runs at 2.6 GeV. (40 min of solid beam time, 1.3h assuming 50% efficiency.)
   • 10:30am: ask tech to come in to flip polarity for HMS and be present for flipping SHMS: 1h?
   • 2h of data at 3.4 GeV. (1h of solid beam time, 2h assuming 50% efficiency.)
   • Change momentum settings to 2.6 GeV (30 min)
   • 2h of data at 2.6 GeV. (1h of solid beam time, 2h assuming 50% efficiency.)
4. Tuesday Swing: continue reference cell runs.
   • 16:00: ask tech to come in to flip back polarities for HMS and SHMS (1h?). Set momenta to 3.4 GeV kinematics
   • 2h of Ref. Cell N2 runs at 3.4 GeV. Top off N2 pressure to 10 atm if needed. (1h of solid beam time, 2h assuming 50% efficiency.)
   • Fill ref cell with H2 at 10 atm.
   • 6h of Ref. Cell H2 runs at 3.4 GeV. (3h of solid beam time, 6h assuming 50% efficiency.)
5. Wednesday owl: continue reference cell runs.
   • 1h to finish the H2 run a 3.4 GeV
   • Change momentum settings to 2.6 GeV (30 min)
   • 3h H2 run a 2.6 GeV. (1.5h of solid beam time, 3h assuming 50% efficiency.)
   • 1.5h BCM calibration (non invasive)
6. Wednesday day: Restore production of polarized 3He at 3.4 GeV
   • 8:00am or whenever the polarized beam is becoming imminent: change momentum settings to 3.4 GeV (30 min)
7. If we have time left with unpolarized beam (good running efficiency, run time with unpolarized beam extended during Wednesday day shift...) We can do optic runs
