System for investigation of hydrogen isotopes - solid body interaction at 500 MPa

This paper describes the system being designed to study the processes of hy drogen isotopes (or their mixtures) interaction with a solid body at pressu res up to 500 MPa. Hydrogen isotopes pressure is produced by a thermodesorp tion source based on vanadium dihydride. Gas is sampled through an intermed iate volume. Cias chromatograph is used to analyze the gas for isotopic com position. Possibility of the system development is exemplified by temperatu re dependencies of equilibrium desorption pressures for vanadium dihydride in a pressure range up to 500 MPa obtained using available equipment.
