Entry number 121407

 E94-107 Shift Plan: Tuesday, May 11, 8:00 am -- Wednesday, May 12,  8:00 am

Continue taking data in the current kinematic setting after Accelerator recovers:

• Beam: E=3.7 (MBSY1C Bdl=943721; check after trips); up to 120uA; FB ON; raster ON at 0.5 x 0.5 mm^2 (full width from spot++); page RC if SLI energy spread >= 3.E-5
• Target: thin 9Be (this is the "thick" target on the target controls)
• Left HRS:   P₀=1.96 GeV/c; I_septum=181.46 A (this is magnet current, not PS; monitor it)
• Right HRS: P₀=1.57 GeV/c; I_septum=145.35 A

Scheduled events/Special tasks:

• The accelerator does not anticipate beam until Tuesday Swing shift. The Tuesday day shift is on STANDBY.
• During the Wednesday and Thursday (May 12 and 13) DAY shifts, Hall C will conduct leakage tests. These shifts are on STANDBY. If the accelerator is up but Hall C cannot take data, the shift will become ACTIVE. Contact the Run Coordinator.

General Tasks:

• When recording settings, check whether they are correct; don't just copy them.
• For each run do detector replay and compare with reference plots.
• After end of run do full physics replay from the ana directory.
• HALOG any detector, DAQ trip and unusual observation when they happen.
  
• Do shift checklist.
  
• Twice a shift HALOG control screens and septum & energy spread strip charts.
• For STANDBY shifts, please HALOG the control screens and magnet strip charts.
• If septa Tcoil >= 7.5 K, HALOG with TECH in title; only 8:00 am - 5:00 pm also call Ed Folts.
• Any problem that prevents data taking and that you cannot solve within 30 min page the Run-Coordinator.
• During night and weekend shifts contact Tech on-call only for emergencies (in doubt page RC). HALOG all events that will require TECH assistance with the word "TECH" in the title.

Known Problems

• N2 level reading right Q3  (CLL72Q310) is  not working properly; ignore
• Dump diffuser cooling water circuit might trigger FSD; after hours page Run Coordinator
