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.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.
