Prospective for large All Silicon Bolometer Arrays for Far Infrared and submillimeter astronomy at CEA.
Abstract
In May 2009, the ESA Herschel Space Observatory was located at L2 (Sun-Earth) by an Ariane V launcher. One month later, a three-colour picture of M51 was the first image released from the observatory. This image was obtained by the PACS photometer, one of the three instruments aboard Herschel. The PACS photometer detectors are, all silicon bolometer arrays with resistive sensors, developed at CEA. These collectively manufactured detectors featured some new developments: light resonant absorption, very high impedance sensors and time domain multiplexing. Today similar focal planes are used in future submillimeter cameras (2013): PILOT a balloon borne observatory for the ISM polarization measurement, and ArTeMiS at the APEX telescope in Chile. We present also the new developments, on these detectors, to improve sensitivity, to extend wavelength coverage to the millimetre domain, and even to include pixel spectroscopic capabilities.
