Gain Notes for Revolution 284 JEM-X1: A completely ordinary revolution that is interrupted by an unscheduled switch-off towards the end of the revolution. Gain smoothing is fine. All data from this revolution should be useable. First two data points on each data set are the pre-switch on with High Voltage 3 steps below its nominal value. The unplanned switch-off demonstrates clearly the effect of fast relaxation (microstrip plate charging) which causes a drop in gain when the High Voltage is switched on again as the charge distribution again finds its equilibrium configuration.
