Author(s) : BRADLEY D. I.

Type of article: Article

Summary

THE ARTICLE DESCRIBES THE DESIGN, CONSTRUCTION AND PERFORMANCE OF A DILUTION REFRIGERATOR SPECIFICALLY INTENDED FOR NUCLEAR COOLING EXPERIMENTS IN THE SUBMILLIKELVIN REGIME. ATTENTION HAS BEEN PAID FROM THE OUTSET TO MINIMIZING SOURCES OF HEAT LEAKS, AND TO ACHIEVING A LOW BASE TEMPERATURE AND RELATIVELY HIGH COOLING POWER BELOW 10 MILLIK. THE REFRIGERATOR USES SINTERED SILVER HEAT EXCHANGERS SIMILAR TO THOSE DEVELOPED AT GRENOBLE. THE MACHINE HAS A BASE TEMPERATURE OF 3 MILLIK OR LOWER. THE HEAT LEAK TO THE INNERMOST NUCLEAR STAGE IS LOWER THAN 30 PICOWATT AFTER ONLY A FEW DAYS' RUNNING.
