End-station for Low Density Matter Beamline at FERMI@Elettra Free Electron Laser — •Viktor Lyamayev, Raphael Katzy, Marcel Mudrich, and Frank Stienkemeier — Universität Freiburg, Physikalisches Institut, D-79104 Freiburg, Germany

FERMI@Elettra is a seeded type Free Electron Laser (FEL), which provides high brilliance femtosecond XUV-pulses in the 20-100 nm range with excellent temporal coherence and wavelength stability. Flexible tuning of both photon wavelength and polarization makes it unique tool for wide range of experiments.

The described setup will be installed as an end-station of the Low Density Matter beamline of FERMI@Elettra, which has been built for studying the interaction of FEL light with neutral molecular beams. It provides several types of sources for generating a wide range of atomic, molecular and cluster beams. Multiple pick-up cells as well as laser ablation can be used for beam doping. A unique detection unit combines time-of-flight, velocity map imaging and X-ray imaging techniques. This allows simultaneous detection of electrons and ions as well as recording of X-ray diffraction patterns.
