A µTCA Back-End Firmware for Data Acquisition and Slow Control of the CLaRyS Compton Camera

With the aim to build a real-time controlled time-of-flight Compton camera for an improved ion-range dose delivery control in hadrontherapy, we have developed data acquisition and slow control back-end electronics for the CLaRyS project. This paper presents a FPGA based firmware architecture, embedded software and associated tools for it, which is able to provide multiple 3 Gb/s optical links for data acquisition, trigger distribution and slow control of the detection system. Performance of the imaging system based on simulations and analysis of the results acquired during test beam measurements are presented. Experiments were performed with the 65 MeV proton beam of the Mediterranean Protontherapy Institute in Nice.
