论文摘要
为了达到探测前所未有的低暗物质质量所需的超低检测阈值,目标材料替代方案和新颖的探测器设计至关重要。这样的目标材料是超流体$^4 $ HE,它有可能探测Sub-Gev质量的未知无知的轻质暗物质参数空间。新的``轻暗物质的直接搜索实验'',Deleast,将使用超流体氦作为主动目标,并用磁性微量含量计。它的设计目的是达到对群众的敏感性,远低于100 \,在暗物质 - 核散射相互作用中。
To reach ultra-low detection thresholds necessary to probe unprecedentedly low Dark Matter masses, target material alternatives and novel detector designs are essential. One such target material is superfluid $^4$He which has the potential to probe so far uncharted light Dark Matter parameter space at sub-GeV masses. The new ``Direct search Experiment for Light dark matter'', DELight, will be using superfluid helium as active target, instrumented with magnetic micro-calorimeters. It is being designed to reach sensitivity to masses well below 100\,MeV in Dark Matter-nucleus scattering interactions.
