LOW-TEMPERATURE REFRIGERATOR WITH COLD HEAD, AND USE THEREOF

PCT No. PCT/EP96/05503 Sec. 371 Date May 20, 1998 Sec. 102(e) Date May 20, 1998 PCT Filed Dec. 10, 1996 PCT Pub. No. WO97/22839 PCT Pub. Date Jun. 26, 1997The invention relates to a low-temperature refrigerator (1) for producing temperatures in a defined low-temperature range, with a cold head (3) which is fitted with a regenerator (6)6) and in which a thermodynamic circulation process (regenerative cold generation process) is carried out to generate cold. To reduce the technical complexity of the cold generation process, it is proposed that the cold head (3) should be a single-stage unit and the physical characteristics of the regenerator (6)7) in the cold machine (1) should be so selected as to ensure that the cold head (3)8) has an optimal cold output in the desired temperature range.
