Target Readiness
- Spin up measurements conducted this morning indicate masing. Upon inducing a gradient, the polarization increased. Need to do follow up tests in the transverse direction.
- Do spin-up tests in the longitudinal direction overnight.
Remaining work
In the enclosure:
- Installing NMR legs and 2 BNC cables. -
- Install EPR fiber bundle cable - later today
- Install Reference cell RTDs - done
- Check the long. + trans. spectral analyses + mounts - done
- Cooling jets alignments - done
- Reference cell gas connections - done
- Target ladder alignment and adjusting the software encoder positions (if needed) - target cell and reference cell look ok (upstream and downstream). For the carbon foils, the beam is
- Install collimators - tomorrow
- Follow the enclosure backout checklist
- Check the angles on QWP in the laser enclosure.
Outside the enclosure:
- Interlock wire broken - done
- General clean up around the pivot area - tomorrow
- Follow the hall backout checklist - tomorrow
Current Run Plan
- Friday: Continue with spin up tests + follow remaining tasks listed above. Go into controlled access.
- Saturday: Install collimators. Close up the enclosure. Start off with 5-pass and wait for MCC to checkout their equipment. Start taking 1-pass data for two days with the same settings as in December.
- Sunday: 1-pass data
- Monday: 1-pass data --> remove collimators and close the panels. Transition to 5-pass.
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.
- 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[1]
- Temporary Laser instructions can be found here [2]
Ongoing Work in the Hall
Planned Accelerator Configuration Changes
Special Requests
- Keep target expert schedule filled out on whiteboard
