ODIn — A setup for Off-line Deposit Irradiations of thin layers for nuclear physics applications

A table top setup was developed for the irradiation of thin layers with low-energy electrons and ions of gaseous species. This serves to gain a better understanding of the chemical microprocesses involved during irradiations. The gained insights will complement the understanding of heavy-ion beam induced transformations at on-line facilities and will be used to develop an accelerator-independent method to transform freshly produced targets into a long-term stable form. The pilot experiment for these Off-line Deposit Irradiations (ODIn) is installed at the Helmholtz Institute Mainz. The setup, beam characterization and first commissioning are described.
