Upgrade of the Giessen MaMFIT — Marc Keil1, Stefan Schippers1, •Alfred Müller2, and Alexander Borovik Jr1 — 1I. Physikalisches Institut, Justus-Liebig-Universität Gießen — 2Institut für Atom- und Molekülphysik, Justus-Liebig-Universität Gießen
A Main Magnetic Focus Ion Trap (MaMFIT), a compact tool for spectroscopy of highly-charged ions [1], has been recently installed in Giessen and has already been employed for investigation of dielectronic recombination in highly-charged iridium ions [2]. The original construction, however, permitted experimental access almost exclusively to the ions of the sputtered cathode material, which, presently, is iridium. The main reason for this restriction is the process of evaporative cooling [3]. We report on an upgrade of the MaMFIT in Giessen. A gas inlet system enabling fine-dosed supply of gaseous elements has been designed, built and installed. In addition, a system facilitating periodic dumping of the ion trap has been set up. These measures have greatly enhanced the versatility of the MaMFIT. Now, a much wider spectrum of elements can be accessed. Results of the reference measurements using highly-charged argon ions will be presented. [1] V. P. Ovsyannikov, (2014) arXiv 1403.2168. [2] A. Borovik, Jr et al., to be published. [3] M. B.
