DARk matter WImp search with liquid xenoN（达尔文（2））将是一个直接探测暗物质的实验，其核心是一个多吨级的液体氙时间投影室。它的主要目标将是探索实验可访问的参数空间弱相互作用大质量粒子（WIMPs）在一个广泛的质量范围内，直到中微子与目标的相互作用成为一个不可约的背景。利用真空紫外灵敏的超低本底光电传感器，可以观测到氙中粒子相互作用引起的瞬时闪烁光和电荷信号。除了对质量超过5 GeV/c（2）的WIMP具有出色的灵敏度外，这种具有大质量，低能阈值和超低背景水平的探测器还将对其他稀有相互作用敏感。它将搜寻太阳轴子、银河系轴子类粒子和中微子-136的无中微子双β衰变，并测量低能太阳中微子通量，
DARk matter WImp search with liquid xenoN (DARWIN(2)) will be an experiment for the direct detection of dark matter using a multi-ton liquid xenon time projection chamber at its core. Its primary goal will be to explore the experimentally accessible parameter space for Weakly Interacting Massive Particles (WIMPs) in a wide mass-range, until neutrino interactions with the target become an irreducible background. The prompt scintillation light and the charge signals induced by particle interactions in the xenon will be observed by VUV sensitive, ultra-low background photosensors. Besides its excellent sensitivity to WIMPs above a mass of 5 GeV/c(2), such a detector with its large mass, low-energy threshold and ultra-low background level will also be sensitive to other rare interactions. It will search for solar axions,galactic axion-like particles and the neutrinoless double-beta decay of Xe-136, as well as measure the low-energy solar neutrino flux with
