Abstract

Si:Ga DVR detector arrays specially designed for broad-band observations in the 10 μm atmospheric window, are currently developed by the LETI/LIR. The originality of these detectors is a large capacitance able to store the huge number of electrons generated by the 10 μm background photons. A prototype array with 32*32 pixels has already been delivered to the Service d'Astrophysique, at Saclay. A 64*64 array with a full well capacity of more than 2.107 electrons will be delivered in the middle of this year. This paper brings up the results of the first set of tests on the 32*32 prototype.
