Radiation Laboratory

The Radiation Laboratory is devoted to characterise radiation detectors based on a semiconductor material such as Cadmium Zinc Telluride (Cd(Zn)Te) or Silicon (Si) useful for High Energy Astrophysics experiments, although it can also be used for other research areas profiting from the available instrumentation. The available equipment allows performing spectroscopy measurements at room and low temperature in the X and Gamma-ray range (from tens of keVs to 1-2 MeV). The Laboratory is a 3rd category radioactive facility authorized by the Spanish Nuclear Safety Council with the number IRA-3137.
