Non-evaporable getter (NEG) coatings are widely used in large vacuum systems such as particle accelerators. Since NEG coatings produced at the GSI Helmholtzzentrum für Schwerionenforschung have a finite thickness of typically 1μm, ion beam analysis techniques such as ERDA and RBS are the methods of choice to study element and depth-resolved evolution of the getter film during gas pumping. The film...
Ion–beam-loss induced desorption is a well known intensity limitation for high current, low charge state heavy ion accelerators like the heavy ion synchrotron SIS18 at GSI. Therefore dedicated measurements of desorption yields has been made, e.g., at CERN and at GSI in the last few years. In this work we will present studies performed at GSI starting from purely phenomenological pressure rise experiments...
