Description
A real-time waveform monitoring system has been developed for the pulsed
power supplies in the injection chain of the Taiwan Photon Source (TPS).
The system covers eight kicker and septum magnets spanning the Booster
Ring and Storage Ring injection path. Two operational incidents involving
SR Injection Septum~1 motivated its development: in both cases, waveform
anomalies that were imperceptible by visual inspection led to severe
injection efficiency degradation or complete injection failure. The system
acquires waveforms via EPICS Channel Access, computes shot-averaged
deviations from a stored reference, and compares them against
physics-motivated alarm thresholds derived from dedicated machine study
experiments. The thresholds are expressed as time-resolved curves that
directly map waveform error to injection efficiency degradation. The
system has been deployed and is currently in operation at TPS.
