System for liquefying or freezing xenon

Apparatus for producing liquid or solid xenon comprises a duct 12 having an inlet 14 for receiving gaseous xenon and an outlet 16 for outputting gaseous xenon at a reduced temperature to a nozzle located in a vacuum chamber 60. A housing 18 extends about the duct and contains a halocarbon coolant in...

Zusammenfassung:	Apparatus for producing liquid or solid xenon comprises a duct 12 having an inlet 14 for receiving gaseous xenon and an outlet 16 for outputting gaseous xenon at a reduced temperature to a nozzle located in a vacuum chamber 60. A housing 18 extends about the duct and contains a halocarbon coolant in thermal contact with the duct, and a second duct 24 in thermal contact with the halocarbon coolant for conveying a flow of liquid nitrogen through the housing 18 to 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.
