Abstract
The radio frequency (RF) laboratory hosted in the Corpuscular Physics Institute (IFIC) of the University of Valencia is designed to house a high-power and high-repetition-rate facility to test normal conduction RF accelerator cavities in the S-Band (2.9985 GHz) in order to perform R&D activities related to particle accelerator cavities. The system, which manages the entire process of RF signal generation, data acquisition and closed-loop control of the laboratory, is currently based on a modular and compact PXI platform system. This contribution details the development of a platform with similar features, but which is based on open architecture standards at both the hardware and software level. For this purpose, a complete system based on the μTCA platform has been developed. This new system must be able to work with accelerator cavities at other operating frequencies, such as 750 MHz, as well as to explore different options at firmware and software levels based on open-source codes.

The IFIC [1] high-gradient radio frequency (RF) laboratory is designed to house highpower infrastructure with which to test S-Band normal conduction RF accelerator cavities.The main objective of the facility is to develop S-Band high-gradient accelerator structures and contribute to the study of very high field non-linear electromagnetic phenomena, known as breakdowns.The type of structures that can be studied in the laboratory are copper-made traveling wave accelerating cavities for linear accelerators with a central operating frequency of2.9985 GHz
An LO frequency of 718.75 MHz has been used in order to obtain the 31.25 MHz intermediate frequency (IF), which is sampled by the 125 MSPS ADCs and yields four samples per period, as needed for the quick I-Q demodulation
Summary
The type of structures that can be studied in the laboratory are copper-made traveling wave accelerating cavities for linear accelerators with a central operating frequency of. These cavities work in pulsed mode at a repetition frequency of up to 400 Hz and with a duty cycle of two parts per thousand. This means that during a period of 2.5 ms, the cavities are fed with the RF signal only for a time of up to about 5 μs, i.e., the duration of the RF pulse which accelerates the beam of particles through the cavity. Linear accelerators for protons or carbon ions that operate at a 100–400 Hz repetition rate can vary the energy (and intensity) of the beam during the
