论文摘要
我们发现，在第三或第四个沙丘样模块中，可以通过对放射性刺激性进行仔细控制，并对类似于Dune FAR探测器设计的检测器进行一些修改，从而提高对低能物理的敏感性。特别是，通过改进的MEV规模范围，可以增强对超新星和太阳中微子的敏感性。具有$^{136} $ XE加载的中准双β衰减搜索似乎可行。此外，对这种检测器中计划的世界程序的敏感性（WIMP）暗物质（DM）变得更有竞争力，提供了一种独特的季节性变异检测，这是WIMPS性质的特征。
We find that it is possible to increase sensitivity to low energy physics in a third or fourth DUNE-like module with careful controls over radiopurity and some modifications to a detector similar to the DUNE Far Detector design. In particular, sensitivity to supernova and solar neutrinos can be enhanced with improved MeV-scale reach. A neutrinoless double beta decay search with $^{136}$Xe loading appears feasible. Furthermore, sensitivity to Weakly-Interacting Massive Particle (WIMP) Dark Matter (DM) becomes competitive with the planned world program in such a detector, offering a unique seasonal variation detection that is characteristic for the nature of WIMPs.
