Semiconductor radiation detectors are used in a large variety of fields in science and technology, including nuclear physics, elementary particle physics, optical and x-ray astronomy, medicine, and material analysis. Among the semiconductors, silicon is by far the most used mainly because of the material availability and the highly advanced process techniques. These two advantages allow the production of high-quality, reliable sensors.

SRS has been working in this field for more than fifteen years, obtaining important results such as the mass production of silicon strip detectors for the AMS and ALICE experiments. In the last few years the activity has become even more important thanks to the development of new highly impacting technologies, such as Silicon Photomultipliers, which led to the participation of the group to important EU projects and to the collaboration with multinational companies.
