Current Status
- Online Analysis Update and instructions???
- Priority: Target Work
- Working on maximizing long. laser polarization
- Techs and Radcon will be here at 7am to close up enclosure (~6hours)
- Spectrometer Magnets Off (Alarms Masked)[1]
- PNMR FID signal can't be found. System can be troubleshooted in CH. [2]
- 3 NMRs are working
- EPR is working [3] but noisy [4]

Current Run Plan
- Run Plan
- Energy measurement at 5-pass [8]
- Day by Day Options [9] Can we add Moller shift Monday Swing if we have 5-pass (For accidental study)?
Notices in Effect for Shift Crew
- Policy for CANS-related hall status change: Make a logbook entry when the hall goes in, or comes out of laser-controlled access.
- Magnet policies
- HMS Q1 must be ramped down in 50A steps in all cases
- Do not ramp HMS Q2 to zero, only go to 10A and then switch off power.
- There IS a lock available for the ramp rate. I will post instructions on how to check if it was on.
- Inform the RC of any access that the Target Team requires. The RC will coordinate with RadCon to make everything run smoothly.
- The operators have been somewhat careful with our beam orbit locks. Please make sure that the orbit locks are enabled and the beam does not drift from its nominal position.
Current Issues
- Long. Laser
- SHMS Dipole Power Supply
- HMS Dipole LN2 overfilling (Will check tomorrow
