An approach to a novel particle detector concept based on liquid rare gas mixtures is presented. The newly found emissions of a liquid Ar-Xe-mixture consists of two intense peaks in the IR and VUV, respectively, separated by 800 nm, more than the whole visible spectral range. Due to the intrinsic detector responsivities, it is possible to use different detectors to obtain two independent scintillation signals on a pure optical basis.
The goal of this work is the search for a particle dependency of the intensity ratios or the time structure of both emissions. The experiments will be carried out at the tandem accelerator of the Maier-Leibnitz-Laboratorium in Garching, using different particle beams at low energy and current.
This research is supported by the DFG cluster of excellence "Origin and Structure of the Universe" (www.universe-cluster.de) and by the Maier-Leibnitz-Laboratorium in Garching.
