This paper describes the use of an in situ ion beam analysis facility developed at Los Alamos National Laboratory for the study of irradiation effects in ceramic materials. In this facility, an analytical beamline of 3 MV tandem accelerator and an ir

The use of elastic nuclear resonances, including 12 C(α, α) 12 C, 14 N(α, α) 14 N and 16 O(α, α) 16 O, provide a useful means of enhancing the sensitivity toward light elements using the same experimental setup as for Rutherford backscattering.

We report the investigation of ion-beam-induced densification of sol-gel zirconia thin films via in situ ion backscattering spectrometry. We have irradiated three regions of a sample with neon, argon, and krypton ions. For each ion species, a series

Densification of sol–gel zirconia films was achieved using ion implantation instead of conventional heat treatment. Densification was observed with Xe+-ion doses as low as 1014 ions/cm2. Ion implantation resulted in hydrogen and carbon losses as me

We have demonstrated that the content of hydrogen in carbon-based films can be reliably calculated from a measurement made either directly using forward recoiled hydrogen or indirectly using backscattered helium. The method makes use of the surface s
