Detectors


Research on photon and radiation detectors at IFN-Roma started long ago in the framework of the activities on superconducting devices. Thanks to the small emergy gap typical of superconductors, these materials provide  a very efficient and sensitive way of converting incoming radiation, within a wide range of wavelengths, into excess population of quasi-particles and eventually into heat. By playing with thickness, geometries, thermal isolation, different types of detectors can be envisaged that can be tailored to achieve the desired characteristics in terms of bandwidth, energy resolution, detection efficiency, counting rate, position sensitivity and so on. 
At IFN-Roma we focus on the following main architectures:
