The development of free-electron lasers with photon energies in the XUV to X-ray regime opens up new possibilities to investigate non-linear laser-matter interaction. Ionic systems with only one active electron are of particular interest - especially hydrogen-like systems.
To investigate such systems we have built and commissioned the HILITE (High-Intensity Laser Ion-Trap Experiment) Penning trap. The ions are produced by an Electron-Beam Ion Trap (EBIT), selected by a Wien filter, and captured dynamically in the trap centre.
Last year we conducted our first Beam time at the FLASH2 FEL laser facility at DESY in Hamburg, where we wanted to investigate two photon ionisation of O5+. We have had to deal with unexpectedly bad vacuum conditions which limited the storage time and significantly increased the background signal.
We will present the setup, the commissioning results and results from our first beamtime. We will also present envisaged upgrades of the setup.
