Status Report of the Projects LISEL@DREAMS and ELISE@IBC — •Oliver Forstner1, Shiva Prasad Pulipati1, Thorben Niemeyer2, and Klaus Wendt2 — 1Friedrich-Schiller-Universität Jena — 2Johannes-Gutenberg-Universität Mainz
The German Ministry of Science and Education has granted funding for the two consecutive research projects LISEL@DREAMS and ELISE@IBC to advance laser photodetachment as an additional element selective filter in AMS. At Jena an ion beam apparatus and an ion beam cooler has been built allowing to study and improve the capture of negative atomic and molecular ions with the goal of increasing the photodetachment efficiency. In Mainz two types of tuneable laser systems have been built. One system based on a Ti:sapphire and a second based on a OPO from Hübner Photonics. Both systems operate in different wavelength ranges allowing to study a broad range of isotopes.
In this status report we will present what has been achieved so far covering the activities at the setup in Jena and the Mainz laser systems as well as connected activities at the FLSR storage ring in Frankfurt. An outlook will be given into the future applications of the developed systems.
