Summary

ONE OF THE REQUIREMENTS FOR THE USE OF SENSITIVE INFRARED DETECTORS IS THAT THE ENTIRE INSTRUMENT BE COOLED TO TEMPERATURES APPROACHING ABSOLUTE ZERO. THE CRYOGENIC COOLING SYSTEM IS USUALLY A LARGE DEWAR CONTAINING LIQUID HELIUM. THUS, THERE IS A NEED FOR A REMOTELY CONTROLLED, MOTORIZED CRYOVALVE THAT CAN OPERATE OVER AN EXTENDED PERIOD OF TIME IN CRYOVAC CONDITIONS. THE PAPER DESCRIBES THE DESIGN, TEST, AND APPLICATION OF A MOTORIZED CRYOVALVE DEVELOPED AT THE LOCHE PALO ALTO RESEARCH LABORATORY.
