Abstract

The REX system is based on a linear electron accelerator and a removable head containing an electron to X-ray converter with its collimator. The machine and the irradiation chamber were manufactured and commissioned at ENEA Frascati Research Center. The activity of the Laboratory for Development of Particle Accelerators and Medical Applications is dedicated to the development of particle accelerators (electrons and protons) for medical, industrial and research applications, realized as sections of complex equipment or as stand-alone machine and offers related services to the scientific community. The REX facility is a versatile irradiation machine thought to be used for experimental campaigns in different research fields thanks to its customizable beam. Some of the cases we performed are related to irradiation of biological systems, development of in-beam monitoring devices, test of beam monitors, material radiation damage studies and cultural heritage. Experiments are carried out for specimen treatment with the two-radiation quality: electrons and X-rays. An overview of the laboratory and of the activities performed with the REX facility in its present status are given in this work and specific attention is devoted to the application on the cultural heritage for the preservation and conservation of artefacts.
