The DARWIN full diameter test platform — •Florian Tönnies — Albert-Ludwigs-Universität Freiburg, Deutschland

In the last two decades liquid xenon TPCs have proven to be a very successful tool in the search for WIMP dark matter and other science channels. The detectors became bigger with every generation and the next generation and probably the final evolution stage of xenon TPCs for dark matter search will be DARWIN, which is planned to emply 50 tons of xenon. As it is almost twice the height and diameter of its direct predecessors currently under commissioning, its hardware components needs adequate testing at this new scale. For this purpose the DARWIN full-diameter test facility PANCAKE was developed and is being set up in Freiburg. We present it's unique features, design challenges, subsystems and first test results.
