Rare experiment leads to discovery of new material defect mechanism

A new material defect mechanism was discovered after Los Alamos researchers and their collaborators achieved a technically challenging experimental setup that employs a rare capability.

This was the first experimental study to use a nondestructive depth-resolved positron annihilation lifetime spectroscopy (PALS) beam to probe the damage profile in ion-irradiated metallic systems. Radiation damage, which causes material defects, is a research topic of high importance, and this experiment contributes data needed to improve material defect simulations.
