keyword=Compton Cavity has been restored
I optimized the beam alignment and the maximum cavity power is at around 1.3 kW (we are loosing power every day !). I changed the locking threhold and gain in cavity flip script so that cavity locks according to a new reflection signal level.
Compton DAQ re-started and cavity is flipping fine. The background rate looks poor and signal to background ratio is almost 1.0. At this point if MCC couldn't improve the background, we may have to try a vertical scan to see we are still optimized at interaction point.
