Abstract

Molybdenum targets are exposed in the DIONISCS experiment to a deuterium (D) Plasma (Gamma(D) similar to 10(21) m(-2) s(-1)) at target biases of 30-350 V and target temperatures of 300-700 K while simultaneously diagnosing the D in the surface with a 3.5 MeV He-3 ion beam. The He-3 diagnostic beam creates displacements in the Mo lattice which can then trap D, allowing retention far beyond the plasma ion implantation range. The conversion of displacements to trap sites averaged over the ion range is non-linear with a scaling (dpa)(alpha), 0.25
