Submillimeter Astronomy in France

Authors:
P. Encrenaz
Abstract:
Submillimeter astronomy has been selected as the top priority for the next decade by the french space agency (CNES). A balloon borne telescope of 2m of diameter is built by Matra-Space, using the lightest CFRP materials. The petals of the telescope have been recently delivered: the telescope will be diffraction limited at 150 ┬Ám, and the pannels will be adjusted during flight. A pointing accuracy of 5" is anticipated. The first flight from Sicily to Spain is scheduled for 1992 with a set of bolometers cooled to He3. The first heterodyne receiver will fly in 1993. It consists of a cooled schottky receiver at 380 GHz to observe simultaneously H20 and 02. The trilayer Nb/Al203/Nb junctions may be used for the first flight. In collaboration with Cal Tech and Jet Propulsion Laboratory, a proposal for a small submillimeter satellite called SM3 (T. Phillips in the P.I) has been selected for a phase A by CNES. Related technological developments are funded in the area of cryo coolers, adjustable pannels in flight, quantum well devices and local oscillator sources, and manufacturing of SIS junctions.
