Summary

A LIQUID HELIUM CRYOSTAT, DESIGNED FOR COOLING SUPERCONDUCTING TUNNEL JUNCTION MIXERS, HAS BEEN CONSTRUCTED WITH A SUFFICIENTLY LOW BOIL-OFF RATE TO MAINTAIN 4 DM3 OF LIQUID HELIUM AT A TEMPERATURE OF 3.7 K FOR MORE THAN 10 DAYS WITH FULL HEAT LOAD. THE CRYOSTAT HAS BEEN USED IN THE LABORATORY AND ON THE NEW CALTECHSUBMILLIMETRE TELESCOPE FOR THE PAST 2 YEARS AND HAS BEEN SPECIFICALLY DESIGNED FOR MAXIMUM LIQUID HELIUM HOLD TIME, EASE OF USE AND TO WITHSTAND THE VARIOUS FORCES ARISING FROM TELESCOPE OPERATION.
