Description
Low-Level RF (LLRF) systems are fundamental to the precise control of accelerating fields in modern particle accelerators, ensuring the required stability in amplitude and phase to achieve consistent beam quality. As accelerator technologies evolve toward higher frequencies and more compact designs, the X-band regime is increasingly adopted due to its support for high-gradient structures and ultra-short RF pulses. However, the shift to X-band introduces greater sensitivity to phase noise, timing jitter, and thermal fluctuations, requiring a new generation of LLRF controllers with faster signal processing and tighter control loops. In this context, a dedicated X-band LLRF prototype has been developed to meet the demanding requirements of the future EuPRAXIA@SPARC_LAB LINAC, as part of the EuPRAXIA Doctoral Network. The prototype integrates a high-speed front-end and back-end system optimized for fast pulse processing and enhanced signal fidelity. It is now prepared for full evaluation on a real accelerator test bench at the TEX facility, INFN-LNF. This paper presents the concept, implementation, and readiness of the prototype system.
