Photon-induced fluorescence spectroscopy (PIFS) — •Philipp Reiß, André Knie, and Arno Ehresmann — Universität Kassel, Institut für Physik und Center for Interdisciplinary Nanostructure Science and Technology, Heinrich Plett Str. 40, 34132 Kassel, Germany

Fluorescence spectroscopy and polarimetry of atoms and molecules is a versatile tool to investigate the final or intermediate decays of the ionic or neutral product. Over several years an apparatus has been built for this purpose.

This PIFS apparatus is designed to operate at synchrotron radiation beamlines, having synchrotron radiation as the excitation source of the atoms or molecules. The fluorescence light is dispersed by two 1m-normal-incidence monochromators and detected by position-sensitive single photon counting detectors. With interchangeable gratings and detectors, the observable range covers 45--800nm. It is possible to extract in a certain spectral range the linear and circular degree of polarization.

Some examples for application of this device is shown, demonstrating the different application fields.
