The Freiburg DARWIN Demonstrator — •Julia Müller — University of Freiburg

Liquid xenon (LXe) time projection chambers (TPCs) are the leading detector technology for searches for dark matter in form of WIMPs. DARWIN will be the ultimate LXe-based dark matter detector covering the entire accessible parameter space for WIMP masses above a few GeV/c², superseding current detectors in size and sensitivity. The technical realization of its central low-background TPC with a diameter of about 2.6m will be very challenging due to the size of the detector, the low-temperature operation, and the required radiopurity levels. The DARWIN detector test platform PANCAKE at the University of Freiburg will be used to develop and test flat detector components with diameters up to the DARWIN-scale. We will present an overview of the platform that can accomodate up to 400 kg of xenon gas and present first results from the commissioning phase.
