Description

Compact, high-gradient linear accelerators increasingly employ X-band RF technology, placing stringent demands on amplitude and phase stability especially for short RF pulses. Meeting these demands requires low-level RF (LLRF) systems capable of precise signal generation and acquisition, with careful management of phase noise, timing jitter, and thermal effects. An X-band LLRF prototype has been developed within the EuPRAXIA Doctoral Network to address these requirements for next-generation linear accelerators. The prototype integrates a high-speed analog RF front-end with an FPGA-based digital platform for pulsed RF generation, acquisition, and signal processing. Its performance was characterized through laboratory measurements and subsequently evaluated on an accelerator RF test bench. This poster presents the system architecture, validation methodology, and experimental results, focusing on pulse-to-pulse amplitude stability and phase noise performance. The measurements demonstrate the feasibility of the proposed approach and provide a foundation for further development and deployment at high-gradient X-band accelerator facilities.
