A high-speed turbine expander has been built as part of a cold-moderator refrigerator for the Argonne National Laboratory (ANL). The design parameters and the operating characteristics of the turbine expander are presented along with the general requirements of the refrigerator. The refrigerated moderator is to be placed near a nuclear reactor to provide an intense beam of low-energy neutrons, and is to operate for continuous periods of up to 6 months. The anticipated scope of the low-energy neutron requirements indicated that the refrigerator had to be designed to operate in the 20° to 30°K temperature range with a 1000-W capacity. In addition, to avoid the hazards associated with liquid and gaseous hydrogen, helium gas was specified as the refrigerator fluid.
