    Run Plan (Please HALOG it if you find something strange or wrong; Call RC if the problem is not resolved within 10 minutes)

    1. Take production data at 100 uA! Watch the lumi widths to see if anything changes. Please check the histograms on the online data monitor with the reference ones on the shift how-to page (http://hallaweb.jlab.org/experiment/HAPPEX/opmanual/opmanual.html#HPXStartingonlineanalysis).

    2. Take Compton data! You will need to start a new Compton run every two hours. The CODA screen to start and stop the Compton runs is in the back room.
      • If compton experts are in back room to do some tests, follow their plan.
      • If the background rates get too high, the Compton HV will trip off and you won't be able to take data. If you cannot keep it going, page Megan Friend (584-0038).

    3. Change the half-wave plate state when we get to 1M good pairs. Follow the instructions for doing this and running the flipper script here: http://hallaweb.jlab.org/experiment/HAPPEX/opmanual/opmanual.html#ChangingHalfWavePlate

    4. Run spot++ every couple of hours and log it. Make sure the prescale factors are PS8 = 1 and PS1 = PS2 = 99999.
