Hydrogen Pressure Regulator with High Absorption Rate

Abstract

By evaporating titanium in an argon atmosphere a deposit consisting of a very fine powder (particle size about 100 Å) is obtained on the inner wall of a metal cylinder. After this powdered titanium has been made to absorb whatever hydrogen isotope is being used, the gas pressure is adjusted by heating the metal cylinder to a certain temperature. Compared with more familiar systems, this pressure regulator has the advantage that equilibrium pressure establishes itself very quickly. One application of the regulator is in sealed‐off neutron tubes.
