Trapping of highly charged ions with an electrostatic ion trap

In the current contribution, we present our first results with an electrostatic ion trap which has been constructed at LKB (Laboratoire Kastler Brossel) in collaboration with the Weizmann institute. The electrostatic ion trap is composed of two coaxial electrostatic mirrors, working for charged particles in the same way as a Fabry-Perot interferometer works for light in the optical regime. The trap has been attached to the beamline of SIMPA (Source d'ions Multichargs de Paris) an Electron Cyclotron Resonance Ion Source (ECRIS) at LKB (Laboratoire Kastler Brossel) and INSP (Institut des NanoSciences de Paris). The trap is foreseen to be applied for various studies on highly charged ions; as measurements of the life times of metastable states, mass spectroscopy etc. First results for trapping highly-charged ions are presented and simulations in order to explain the observed behavior are discussed.
