Abstract

A vertically loaded shaft cryostat based on a closed-cycle cryocooler built around a Sumitomo SRP-062B pulse tube has been developed. The cryostat is intended for investigating the structure and phase transformations of materials via neutron diffraction experiments on samples at pressures up to 10 GPa created in high-pressure chambers with sapphire and diamond an vils in the temperature range of 6—300 K. The cryostat has been tested with the help of the DISK diffractometer of the Russian Research Centre Kurchatov Institute. A high-pressure chamber is loaded into the cryostat through its shaft with the help of an insert. The chamber is cooled by heat-exchange gas (helium-4) an d a heat exchanger that is thermally connected with the cryocooler’s second stage. The minimum attained temperature of a sample is 6 K. The drift diameter of the shaft is 120 mm, making it possible to cool chambers with lengths up to 200 mm (in the vertical orientation) and 110 mm (in the horizontal orientation). The cryostat has been designed and manufactured at the Frank Laboratory of Neutron Physics of the Joint Institute for Nuclear Research.

Abstract

The results achieved in designing a cryogenic system for the superconducting magnet of the deuteron cyclotron DC-1 are described. The cryogenic system consists of a liquifier-refrigerator with an output of 40 L/h (or 150 W of power removed at 4.5 K), a satellite cryostat for the superconducting magnet coil, and vessels for liquid nitrogen and helium. The superconducting magnet, cryostat cold block, and cooling system are discussed in detail. >
