Description
A traveling-wave transverse RF deflecting structure enables bunch length measurements at the Shanghai High Repetition Rate XFEL and Extreme Light Facility (SHINE). To enhance amplitude and phase stability in this S-band cavity, an efficient LLRF control system implements pulse-to-pulse techniques: feedforward control dynamically adjusts intra-pulse modulator HV amplitude to regulate klystron output power (accelerating voltage), while feedback control stabilizes phase by adapting the low-level RF drive. This paper presents the system's detailed design and implementation.
