General updates
Weekend
- Saturday: solid data (after 2AM SHMS dipole trip)
- Sunday: SHMS Q3 tripped
- Might be mass flow controller, which would be a "quick" fix.
- Worst case scenario could be a blockage that requires warming the magnets up.
Monday
- Moller during day shift
Recent polarization measurements
Didn't have time to compile this today :(
Beam checkout
- The short checkout procedure wiki entry is updated. Feedback is welcome
Current Run Plan
- Always take 120Hz of EDTM
Monday swing – Tuesday day
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !! !! All NMR measurement HCLOG entries should include: !! !! 1) A title that clearly lists polarization !! !! 2) Screenshots of both NMR_FieldSweep and !! !! the polarization fit. !! !! !! !! For an example see the following entry: !! !! https://logbooks.jlab.org/entry/3768696 !! !! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Run plan: https://logbooks.jlab.org/entry/3772076
- General idea: take 4–5 hours transverse data to get polarization up, then ~7 hours longitudinal
Future
Moller & spin dance
- Finally took measurement today! (No spin dance)
- Moller + spin dance on Tuesday 2/4? Are there beam studies scheduled for 1/28?
Hall Access
- Thursday morning
- SHMS Q3
- EPR fiber bundle, maybe laser alignment
- SAF112 walkthroughs with Joe at 9AM on Thursday
- PSU (under pivot) for polhe3 rack camera and hcreboot5 needs to be manually power cycled [1]
- "hcreboot5 has a number of the target controls on it as well [which?] so we won't be able to power cycle those remotely either until this is done." - Brad
Other
- Replace target cell in ~1 week
Special Requests
- Keep target expert schedule filled out on whiteboard
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.
- If SHMS dipole trips again, take a screenshot of the PSU window before resetting the interlock and post it to hclog.
- 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.
- Ramp rate lock instructions are here and added to checklist[2]
- Temporary Laser instructions can be found here [3]
