keyword=beamline HV tripped offat 0456, the beamline HV tripped off. we verified this by checking the compton stripchart. the photon detector rates had dropped to zero. we stopped the compton run. then we waited for the BEAMLINE HV gui to update showing 0V in the three channels being used for HAPPEX (see fig 2). then we turned the HV crate off and then on (top left corner of gui). the HV slowly ramped back up. we verified that the readback voltages were within a few volts of the set voltage. looks okay (see fig 1). started a new compton run. compton rates look ok @ 0515...
