Abstract
A Recondensing-type cryostat cooling system, which can supply liquid helium to three machines to test material fatigue at liquid helium temperature, was developed. By the use of a Claude-type refrigerator and distribution of the individually to recondensers installed in the cryostats of the three machines, each of which has a different function, the specimen in each cryostat can be kept at liquid helium temperature independently. During test operation of this system for 500 hours, each cryostat was cooled, warmed and recooled selectively so as not to disturb the stability of the other refrigerating cryostats. As a result, it was proven that the developed system makes it possible to efficiently carry out a diversity of fatigue tests at liquid helium temperature.
