✦ Synopsis

The new generation of miniature 3He refrigerators, exploiting only the condensation and cryosorption cycles of 3He 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 improved 3He 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 standard 3He refrigerators, without using any thermal switch. The system has the potential to be very useful in all applications where several modifications are required.

The sensitivity increase in bolometers obtained by operating temperatures of 1 K (helium-4) and 0.3 K (helium-3), with respect to standard bolometers cooled at pumped 4He temperature, represents in infrared and submillimetric astronomy a remarkable step forward in applications both on large ground t
