Title: The Effects of a Hydrogen Environment on the Lifetime of Small-Diameter Drift Chamber Anode Wires

Possible deterioration of anode sense wires used in a hydrogen-filled neutron detector is investigated. Wires were loaded with free weights and put into a wire detector environment. Stainless Steel, Tungsten, and Platinum wires did not break after exposure to charge equivalent to many wire lifetimes. Furthermore, exposure to hydrogen gas caused no noticeable surface degradation or change in wire yield strength.
