MAD-4-MITO, a Multi Array of Detectors for ground-based mm/submm SZ observations

The last few years have seen a large development of mm technology and ultra-sensitive detectors devoted to microwave astronomy and astrophysics. The possibility to deal with large numbers of these detectors assembled into multi–pixel imaging systems has greatly improved the performance of microwave observations, even from ground–based stations, especially combining the power of multi–band detectors with their new imaging capabilities. Hereafter, we will present the development of a multi–pixel solution devoted to Sunyaev–Zel’dovich observations from ground–based telescopes, that is going to be operated from the Millimetre and Infrared Testagrigia Observatory.
