ATRON, a technological platform rich in scientific expertise, meets your irradiation needs and supports you in your R&D projects. ATRON was born from a strong ambition of CERAP, a subsidiary of the ENGIE group, to consolidate its positioning in nuclear instrumentation using a breakthrough technology that aims to abandon the use of radioactive sources in favor of controlled irradiation. In partnership with CNRS and CEA laboratories, ATRON performs calibration of radiation meters with an electron beam and an X irradiation field connected to a primary irradiation source. To achieve its project and meet various irradiation needs, ATRON has developed a technological platform equipped with an electrostatic electron accelerator with a removable X target, tools allowing irradiation in special conditions, a measurement and analysis laboratory, a team with scientific skills, a network of partnerships with research laboratories. ATRON has benefited from the support of the Normandy region for the implementation of this project.
