Preparation of an EBIT ion source for HILITE — •Tino Morgenroth1,2, Nils Stallkamp1,3, Stefan Ringleb2, Oliver Forstner1,2,3, Manuel Vogel1,3, and Thomas Stöhlker1,2,3 — 1GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt — 2Institute of Optics and Quantumelectronics, Friedrich Schiller Universität Jena — 3Helmholtz Institut Jena
The HILITE experiment is an open-endcap Penning trap setup, which is currently under construction at the GSI facility in Darmstadt. It allows the study of laser-ion interaction with highly-charged ions at high-intensity laser-systems such as JETI and POLARIS in Jena or FLASH in Hamburg. The main topic of our studies will be the observation of non-linear laser-ionisation effects, for which a well-defined ion-target in a desired charge distribution is a basic requirement. The need of the production of well-prepared ions is covered by a commercial EBIT ion source from the Dreebit company. This device produces highly-charged ions by consecutive impact ionization by an electron beam. The EBIT is optimized with respect to the ionisation process, to get a specific charge state of a distinct ion species, as well as the extraction, to get an optimal capturing of highly charged ions in the HILTE Penning trap. The experimental setup as well as results of the measurements of properties of the extracted ions and capture efficiency with HILITE will be presented. An outlook on the planned experimental work will be given.
