  • General considerations
    • Kijun Park is the current Run Coordinator. Please contact directly via RC phone 757-876-1787
    • Follow the generic Instructions for shift takers
    • Shift leaders: Please make sure to fill out the beam time accounting form and write a "Shift Summary" log entry at the end of your shift regardless if there is beam or not.
    • In general, Hall technical staff should not be contacted by the shift crew - please call the RC first.
    • The target operator is required to supervise the cryo-target.
    • Make sure to use the DVCS CODA configuration for all runs (even when taking single arm HRS data).

  • Instructions for this shift
    • 0) Check the beam position
      • - request beam position: BPM A=(+1.5:0.75), BPM D=(+1.5:-0.75) ---- please double check
    • 1) When beam arrives to the Hall
      • - Ask MCC to run the Harps: 1H04A/B (close to target)
      • - halog the results
    • 2) Confirm the beam position using the carbon hole target.
      • - request CW 5uA without raster
      • - check the scaler rate rastered target up to 2x2 or 3x3
      • take LHRS & RHRS run with prescale PS1=1
    • 3) Do SpotL and SpotR
      • - to check the hole is centered on the raster current X vs. Y plot
    • 4) Bullseye scan
      • - once beam is centered
      • - scan with both LHRS & RHRS
      • - PS1=1, PS8=10 : for RHRS
      • - 103kHz = 4096, S0&S2m =1 : for LHRS
