Heavy ion-induced desorption investigations using UHV-ERDA

Abstract

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 to highly sophisticated ion beam analysis techniques like UHV-ERDA.
