The Radiation Detectors Group (RDG) started its activity in 1996 participating in the CERN ATLAS Inner Detector Collaboration with the aim of developing silicon radiation sensors for the tracker system and studying the radiations effects on the devices.

In the last 20 years, RDG has been participating in the development/upgrade of the instrumentation of some of the most important high-energy physics experiments (ATLAS, AFP, TOTEM, CT-PPS, CMS). At the same time, the activity of the group has been broadening out with the development of advanced technologies for many other applications: nuclear physics, medical science, synchrotron and nuclear fusion facilities, space applications, instrumentation for civil security.
