keyword=Compton background ratesIt looks like we benefited from the work on the source requested by Hall B. I just turned the detector back on photon rates are reasonably low aound 220 Hz / uA, electron rate is too slightly too high around 1.8 KHz/ uA. So we might need to spend some time to reduce the background in the Compton. Also just noticed a jump in backgroud a few minutes ago (dark blue line) . Beam position in the chicane looks OK.
