Description

The end of the evolution of dual phase xenon TPCs will be the DARk matter WImp search with liquid xenoN – the DARWIN experiment. In this talk I will discuss the primary physics goal of DARWIN: the exploration of the full experimentally accessible WIMP cross section and mass parameter space before coherent neutrino interactions dominate the count rate. The aim is to obtain a few times $10^{-49}\mbox{cm}^2$ sensitivity for the WIMP nucleon cross section at a WIMP mass of $50~\mbox{GeV/c}^2$. I will focus on the detector design that will be based on a combination of existing well-developed techniques, with possibly new low-background light detectors that may replace PMTs. The scientific success of the DARWIN depends crucially on the ability to suppress backgrounds: both from external neutron and gamma sources and most importantly from internal sources of radon and krypton. If the challenges in construction and backgrounds are conquered, DARWIN will become the most sensitive liquid xenon WIMP detector ever built.
