The new generation of miniature3He refrigerators, exploiting only the condensation and cryosorption cycles of3He without moving parts and external links, represents the most common adopted solution in low temperature physics for cooling detectors such as bolometers at 0.3 K. The characteristics and performance of an improved3He refrigerator working at a temperature of nearly 0.3 K are discussed. We introduce a new class of refrigerator (patented) which allows one to reach the operating temperature in a much shorter time than with standard3He refrigerators, without using any thermal switch. The system has the potential to be very useful in all applications where several modifications are required. © 1996 Elsevier Science Limited.
