Descripción

The DARWIN observatory is a proposed multi-purpose experiment for dark matter and neutrino physics, featuring a 50 tonne (40 tonnes active) dual-phase xenon time projection chamber. To test key technological concepts required for the realization of DARWIN, we built Xenoscope at the University of Zurich, a full-scale vertical demonstrator using 400 kg of liquid xenon (LXe). It will be used as a first-time demonstration of electron drift in LXe over 2.6 m, as well as to study electron cloud diffusion and measure LXe optical properties. To investigate novel candidate photosensors for DARWIN, we further characterize the performance of Hamamatsu R12699-406-M4 flat panel photomultiplier tubes in xenon at our test facility MarmotX. We present an overview of the Xenoscope facility, current and planned measurement campaigns, as well as first R12699 PMT characterization results.
