Abstract

Future ground and space astronomy experiments will require large arrays of sensitive detectors in the submillimeter and millimeter ranges. Superconducting Transition Edge Sensors (TES) are currently under development in many institutes to be used as ultra sensitive bolometers. We are investigating co-evaporated NbSi thin films TES arrays. We present here the characterisation and laboratory performances of an array and its readout electronics.
