APEX RUN-11 IPM Channel2Channel Calibration PI: R. Connolly, M. Minty, S. Tepikian Confirmed that the emittance dependence on beam position at IPM, i.e. separation bumps at IP2 was due to the gain depletion of the MCPs at the center of the measurement aperture

APEX RUN-11 IPM Channel2Channel Calibration Uncorrected data and indicates a vertical beam size increase of 16% or emittance increase of 35% when bump is removed Same data with gain and offset corrections. Now the size change is 5%, about the scatter in shot-shot measurements
