A compact UV/VUV spectrometer with fixed VLS gratings for overview luminescence measurements — •Nils Kiefer, Andreas Hans, Arno Ehresmann, and André Knie — 1Institut für Physik und Center for Interdisciplinary Nanostructure Science and Technology (CINSaT), Universität Kassel,Heinrich-Plett-Straße 40, 34132 Kassel, Germany

We present a design study for the energy resolved photon detection in the UV and XUV energy regime. A grating with Variable Line Spacing (VLS) allows for dispersion of a wide spectral range onto flat detector surfaces. With two VLS gratings on one substrate, spectra from 30nm to 120nm and 120nm to 300nm can be imaged simultaneously, but spatially separated. In order to achieve single photon detection, two position and time resolving MCP-based detectors will be used. Exemplary showcase-applications at FAIR (Facility of Antiproton and Ion Research) and synchrotron radiation facilities will be outlined. With this compact spectrometer with high efficiency and high resolution from 30nm to 300nm, it will be possible to collect time efficiently wide range luminescence spectra in experiments for the characterization of the highly charged ion beams or synchrotron radiation served AMO experiments.
