Abstract
Apparatus for producing liquid or solid xenon comprises a ducthaving an inletfor receiving gaseous xenon and an outletfor outputting gaseous xenon at a reduced temperature to a nozzle located in a vacuum chamber. A housingextends about the duct and contains a halocarbon coolant in thermal contact with the duct, and a second ductin thermal contact with the halocarbon coolant for conveying a flow of liquid nitrogen through the housingto control the temperature of the halocarbon. In view of the difference in the pressure of the xenon gas output from the duct and the pressure in the chamber, the thus-cooled gas is caused to liquefy or solidify in the vicinity of the nozzle.
