Current Run Plan

Normal Production running

  • Prerequisites
    • Make sure the raster size is correct (4-4.5)
    • Monitor beam parameters/configuration very often and post an entry like this at the beginning of your shift and when run conditions have changed
    • Running on cell targets: raster always ON (4-4.5, size will be determined by the scraping checks), orbit locks ON, current ramp rate 1 muA/sec
    • Always take 120Hz of EDTM
    • Fill the BTA with realistic numbers. If the desired beam current is not delivered prorate your ABUs!
    • Change the IHWP every 4 hours when running on glass cells
  • Run plan
    • Start back with the Beam / Raster checkout (short procedure) Checkout
    • Production on 3He; if not able to reach requested current, pro-rate the ABUs

Notes for tomorrow's 7:45 meeting

Future

  • Opportunistic target polarization calibration and studies on Tuesday-Wednesday during beam off and Moller measurement (priority is beam)??
  • We are on the schedule to switch to 1st pass on Monday/Tuesday (17AUG / 18AUG). Need about ~ 3 days at 1st pass and would like to switch back to 5th pass before the weekend.
  • EPR diode good for now, but check for future planned accesses.
  • If Hall will have opening for 1+ hours, let Simona know as there is work to do on the cerenkov.
