Description
Liquid argon-xenon mixtures show intense scintillation in the vacuum-ultraviolet (VUV) and at the same time in the near infrared (IR). Optical spectroscopy of liquid argon and argon-xenon mixtures has been studied using both ion- and electron beam excitation. Presently we investigate liquid argon-xenon mixtures as a potential detector material. In particular we want to learn if a comparison of VUV and IR emission can be used for a purely optical particle identification. The experiments are performed at the Munich Tandem accelerator (MLL).
