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 Millimeter and Infrared Testagrigia Observatory.
