Design of an isotope separator for target production — •Dominik Studer1, Rugard Dressler2, Ulli Köster3, Dorothea Schumann2, and Klaus Wendt1 — 1JGU Mainz — 2PSI Villigen — 3ILL Grenoble
With the rising demand for isotopically pure targets for the study of specific nuclear reactions, the construction of a high-throughput isotope separator is foreseen within the SANDA project. Specifically the handling and purification of radioisotopes is mandatory and will be enabled by installation of the whole setup within a radioactivity monitoring area in close contact to a hot lab. In the current project phase the design of the apparatus and establishment of a suitable facility, located at PSI, is planned. The design will be derived from experiences with the RISIKO isotope separator at Mainz University, which has been successfully used for radioisotope purification and implantation, e.g. within the ECHo project. It features a hot-cavity laser ion source. The laser system is based upon tunable pulsed Ti:sapphire lasers with high repetition-rate. Ion extraction from the source region with about 30 kV, electrostatic beam focussing and separation with a conventional double focussing sector field magnet seem most suitable for the task. After passing the separation slit, the ion beam can be re-focused to well below mm size for implantation into detectors, collectors or targets with sub mm control and resolution. In this contribution we present the principles, capabilities and limitations of the RISIKO separator using experimental and simulation data. Improvements which can be implemented in the new SANDA isotope separator are discussed.
