Si:Ga DVR arrays optimized for 10 μm astronomical observations from ground.
Abstract
Si:Ga DVR detector arrays specially designed for broad-band observations in the 10 μm atmospheric window, are currently developed. 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 already exists. A 64×64 array with a full well capacity of more than 2.107 electrons will be available in 1989. This paper brings up the results of the first set of tests on the 32×32 prototype.
