Development of the St. Andre ion beam analysis facility at notre dame

Abstract

A refurbished 3 MV tandem Pelletron® accelerator has been installed in the University of Notre Dame's Nuclear Science Laboratory for the purpose of ion beam analysis applications. A modified Alphatross® ion source provides microAmps of H, He or both ions into the accelerator. Several high-energy beam lines are operational, which allow for internal and ex vacuo ion beam analyses. The external beam capability allows for gamma-ray (PIGE) and x-ray (PIXE) analyses to be conducted simultaneously on targets in atmosphere. Rutherford backscattering (RBS) analysis as well as PIXE can also be performed in a 30" scattering chamber. An overview of the new facility, its commissioning experiments and routine operating procedures will be presented together with some examples of ion beam analysis applications performed to date.
