Compton Procedures Sheet (short version for shift workers)
General Compton running:
1.At least once every hour restart a new CODA run. CODA should be open on one of the desktops of ccomptl1.
2.At least once every hour check the status of the HV. If a trip occurred, see below.
3.Check whether the laser is still flipping (EPICS channel cComptCavityPower).
--> This should be obvious from the camera as well. If not flipping, call an expert. This EPICS PV should be visible on the desktop of Striptools on ccomptl1.
After a photon detector HV trip:
1.Check that the normalized rate on the background scintillator (EPICS channel cComptScintRateNorm, or manually normalize hcrate14) is still below 150 Hz/uA (200 Hz/uA is tolerable, <150 Hz/uA is "good").
--> This EPICS PV should be visible on the desktop of Striptools on ccomptl1. If not, call an expert.
2.Wait 5 minutes after the trip and turn on the HV on the photon detector to 1600 V (channel PhotonDet_6).
--> The HV controls should be open on one of the ccomptl1 desktops. If not log on to cdaql4 as cvxwrks and cd to $EPSHV/tk then run /HV_compton.tcl and turn on PhotonDet_6.
3.If the photon detector HV trips again within 15 minutes, call an expert.
