UHV-ERDA Investigations on Ion Induced Desorption


In heavy ion accelerators the beam line vacuum is effected by lost ions impinging on the beam pipe. Due to ion induced desorption gas is released from the walls into the vacuum. This vacuum degeneration effects the ion beam life time and is a serious luminosity limitation for a heavy ion synchrotron like SIS18. Here we report on a new approach to understand the physics of the ion induced desorption using ion beam analysis. The technique is briefly introduced and first results with a silicon target are presented, showing a clear correlation between the desorption yield and the material constitution.
