Current Status
- RF Recovery started at 8:00 AM
- MCC will try to bring Hall C up to high current (70 uA?) during Swing Shift
- Completed mean-field kinematics and switched to SRC kinematics ---> https://logbooks.jlab.org/entry/4044321
- collected ~ 40-min worth of statistics at 40-50 uA
- will do full analysis / check histograms for better estimates of Ca-40 SRC rates
Current Run Plan
- page 8 of CaFe Run Plan
- Resume beam tune to Hall C / Ion Chamber calibration with "No target" ( DONE )
- Do "Aluminum Hole" check to center BEAM on target ( DONE )
- Do Ion Chamber calibration for solid (using Thorium, 6% R.L.), and cryotargets (LH2, LD2) ( DONE )
- Ramp back up SHMS magnets to do trigger checkout using LH2 ( DONE )
- Do SHMS Hodo HV test / proton absorption / heep normalization ( DONE )
- Proceed to CaFe production @ mean-field kinematics for all targets ( IN-PROGRESS )
- LD2 - DONE
- Al Dummy - DONE
- C12 - DONE
- Ca48 - DONE
- Ca40 - DONE
- Fe54 - DONE
- Be9 - DONE
- B10 - DONE
- B11 - DONE
- Proceed to CaFe production @ src kinematics for all targets ( IN-PROGRESS )
- Ca40 - IN-PROGRESS
- Ca48 - PENDING
- Fe54 - PENDING
- C12 - PENDING
- LD2 - PENDING
- Be9 - PENDING
- B10 - PENDING
- B11 - PENDING
- Al Dummy - PENDING
- Whenever MCC is able to deliver 70-75 uA stable beam current:
- coordinate with D. Mack to do BCM calibrations ( PENDING )
- do Target Boiling study whenever we have LD2 target in place (to save time of having to do target changes) ( PENDING )
Notices in Effect for Shift Crew
- If beam is down, for extended period, take daily 15-min. FADC no threshold run as per Bob Michales instructions, to keep check pedestals and make sure data is not thrown away. This is just as sanity check, and should be done for any running experiment
Current Issues
Planned Accesses to the Hall
- Hall C walkthrough given by J. Beaufait @ 10 AM, while Hall C in Controlled Access (since accelerator is on RF recovery)
