Current Run Plan

• page 7 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

• 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 )

Special Requests

• During RF recovery tomorrow, we would like to schedule a Hall C Walkthrough for some users, but a time frame of when RF recovery will be done is needed. Shawn Frierson has been contacted. Awaiting response . . .
