Abstract

In the framework of the DCMB (Développement Concerté de Matrices de Bolomètres) collaboration we develop low temperature bolometer arrays for large field, high resolution imaging in astrophysics. DCMB is a R&D effort funded by CNES and CNRS involving a number of French laboratories. Two parallel developments have been made in this collaboration based on the NbSi alloy either semi-conducting or superconducting depending on the Nb concentration. Multiplexing schemes have been developed and demonstrated for these two options. Here we focus on high impedance bolometers and present two examples of array developments in progress: first, a 23 pixels array for the balloon-borne instrument OLIMPO and, second, 204 pixels for ground based observations with the 30 m IRAM telescope.
