A new AMS beam line at the Erlangen tandem accelerator facility

Abstract

An accelerator mass spectrometry beam line is presently being built up at the EN tandem accelerator in Erlangen. A new Cs sputter ion source is being developed, and mass separators on both the low- and high-energy sides of the tandem and an electrostatic sector field for charge-state selection have been installed. Optimization of the beam quality will be possible with a new emittance measuring device. The tandem is stabilized via a position-sensitive Faraday cup, which simultaneously measures the current of the abundant isotopes. The spectra of the rare-isotope ions are taken by differential energy loss measurements in a gas ionization chamber.
