Recent IBA setup improvements in Chile

This paper describes the main characteristics of the ion beam facility based on a 3.75 MeV Van de Graaff accelerator model KN3750 of HVE at the University of Chile. Recent setup improvements on three beam lines available, one dedicated for PIXE analyzes, one designed for RBS–PESA analyzes and a multipurpose vacuum chamber, as well as beam energy calibration experiments of the accelerator will be summarized. Current research activities are focused on the application of the different IBA techniques for the material, biological and environmental analysis. In addition, nuclear activation analysis and the study of nuclear reactions of astrophysical interest has begun to be developed as basic research.
