Description
Since 2021, the Self-Excited Loop with Amplitude and Phase (SELAP) control algorithm has regulated CEBAF’s high-Q superconducting radio-frequency cavities, demonstrating robust field stability. Sustaining this performance in routine operations, however, required targeted controller adaptations to mitigate microphonics, cavity-to-cavity mechanical coupling, signal crosstalk, high-power amplifier (HPA) saturation, and heavy beam loading. This paper details the firmware and software implementations developed to address these operational constraints and presents beam-run performance data on cavity availability and trip-rate reduction.
