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

After injector work is completed, please follow the beam recovery procedure, which can be found in the front room of the Counting House.

Verify that beam positions at BPM A and B are within specs. If not, have MCC set them to the correct values.
Take Harp scans with raster off.
Check spot++ with raster on in empty position, before moving to LH2 target.
Before putting beam on the LH2 target make sure we have enough cooling power by opening the JT valve. Flow rate should be less than 25.5 g/s.

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).

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 front room on the DAQ computer (adaql2).
- 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).
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

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

Accept the beam unless the Compton people say that they just cannot use it. Then record it as BNA.
Subtract 1 minute from the ABU after beam trips for 100uA production running.

Make sure that BPM12 is not saturating.
If it does, follow the steps on the HAPPEX Troubleshooting (http://hallaweb.jlab.org/experiment/HAPPEX/troubleshooting.html).
If anyone must reset a magnet, they must make a halog entry stating which magnet on which arm, and what was wrong with it to require a reset. The word "tech" must appear in the subject line.
Be sure that the prompt analysis is done for every run!
The BTA program doesn't subtract any time to speak of for beam trips. Please manually subtract a full minute for each beam trip in the beam time accounting.
Please write a detailed shift summary (including runs taken and any activities) and submit the BTA for each shift.
Please make sure that the shift checklist is done once each shift.
If you have to page or call someone for support, please do so from a counting house phone or it will be ignored!
Keep a close eye on the lumi and detector asymmetry widths as we take data.
Please continue to take runs even if there is no beam. These data can be used to determine pedestals. Please label these runs as having no beam.
