During the last decade, CEA have started a long term program to achieve the collective realization of a large (32x32 pixels) µCalorimeters camera for X-ray Astrophysics. This camera is based on silicon doped sensors with Composite Tantalum absorber readout thanks to HEMT/SiGe based Cryo-Electronics. The goal of this development is to achieve a spectral resolution of about 2eV@6keV with a thermal budget in the order of 1 µW@50mK for over 4000 pixels.
After some delays in the production, we present our first measurements obtained our first 32x32 sensors matrix.
We measured R(T), noise and spread between pixels. We will present our first Cryo-Electronics MUX based results.
