  • 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).
    • Note that ion chamber calibrations have ALREADY been done for: carbon (single foil), carbon (five-foil), LH2, and BeO. See this log entry for the first three and this log entry for BeO. The limits on the ion chambers for these targets were set up for currents up to 20 uA.
  • Instructions for this shift
    • Elastic calibration data (see white board for details, DVCS Calo is positioned at 6.138m + CH block was removed)
  • Configuration
    • 2. setting#2: 2.95GeV/34.30(deg): 2-3hrs
    • 3. setting#3: 2.742GeV/36.20(deg): 1-2hrs

Hopefully, the polarity will be changed in 7AM, if thing goes well.
