| Popis: | Since a decade, CEA has started a long-term program to achieve the collective realization of a large (32 × 32 pixels) microcalorimeter camera for X-ray astrophysics. This camera is based on doped silicon sensors with composite tantalum absorber read out by HEMT-/SiGe-based cryo-electronics. The goal of this development is to achieve a spectral resolution of about 2 eV@6 keV in a thermal budget of ~ 1 µW@50 mK for over 4000 pixels. We present the design of our first 32 × 32 sensor matrix. We also present the steps of the development plan of the first measurements onto our matrix. |
