我们描述了 LUX-ZEPLIN 实验的设计和组装，该实验是对宇宙 WIMP 暗物质粒子的直接探测搜索。该实验的核心是一个对低能核反冲敏感的大型液氙时间投影室。 Xe 皮肤否决探测器和装有钆的液体闪烁体外部探测器可增强背景抑制，以实现高效的中子捕获和标记。 LZ 位于美国南达科他州利德市桑福德地下研究设施 4850 英尺处的戴维斯洞穴内。我们描述了实验的主要子系统及其关键设计特征和要求。
We describe the design and assembly of the LUX-ZEPLIN experiment, a direct detection search for cosmic WIMP dark matter particles. The centerpiece of the experiment is a large liquid xenon time projection chamber sensitive to low energy nuclear recoils. Rejection of backgrounds is enhanced by a Xe skin veto detector and by a liquid scintillator Outer Detector loaded with gadolinium for efficient neutron capture and tagging. LZ is located in the Davis Cavern at the 4850' level of the Sanford Underground Research Facility in Lead, South Dakota, USA. We describe the major subsystems of the experiment and its key design features and requirements.
