Linear accelerators are used in High Energy Physics (HEP) experiments performed in leading laboratories around the world like Deutsches Elektronen Synchrotron (DESY). In order to decrease costs some of them, such as the X-Ray Free Electron Laser (XFEL) located at DESY research centre, are built in a single tunnel. Therefore, part of the accelerators control electronics is located next to the main beam pipe and exposed to destructive influence of gamma and neutron radiation. These kinds of radiation are produced as parasitic effects of normal operation of the linear accelerator....
