The PD called and said they saw an energy tail at 1C12, I moved Electron detector at 30 mm from the beam in and turned photon on so we can see if the rates improved. So far no changes but I guess they might try more things when Dustin is done with the Q2 measurements. In attachement 1 Electron detector currents at 10 uA in attachement 2 current rates with HV of 1520 V, I had to reduce to 1400 V at 20 uA. Electron detector settings where threshold of 12, or of 5 strip per plane and coincidence 2 planes. Photon and electrons are several KHz
