Current Status
- Harp Scans completed (Sep 16 Swing) IHA3H07A --> https://logbooks.jlab.org/entry/4042622 | IHA3H07B --> https://logbooks.jlab.org/entry/4042625
- Downstream beamline valve was shutoff --> https://logbooks.jlab.org/entry/4042671 The issue was resolved by Hall C techs today at 7AM
- Currently receiving tune beam
Current Run Plan
- page 4 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 ( IN-PROGRESS )
- Do Ion Chamber calibration for solid (using Thorium, 6% R.L.), and cryotargets (LH2, LD2) ( PENDING )
- Ramp back up SHMS magnets to do trigger checkout using LH2 ( PENDING )
- Do SHMS Hodo HV test / proton absorption / heep normalization ( PENDING )
- Proceed to CaFe production @ mean-field kinematics for all targets ( PENDING )
- Proceed to CaFe production @ src kinematics for all targets ( 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
- Instructions for moving the target to "Hole" ---> https://logbooks.jlab.org/entry/4042703
Current Issues
- Target is unbale to move to "Hole" position, encoder position has to be put in by hand. D. Meekins / C. Keith currently working on diagnosis. All other targets were tested, and motion was verified.
- During shift checklist, Holly noticed some minor issues --> https://logbooks.jlab.org/entry/4042694
