XENON是一种新颖的液体氙实验概念，用于使用1吨主动目标进行灵敏的暗物质搜索，分布在10个独立时间投影室的阵列中。该设计依赖于同时检测液体氙中的电离和闪烁信号，目标是在逐个事件的基础上提取尽可能多的信息，同时保持大部分目标活跃。氙有望具有有效和冗余的背景识别和辨别能力，高于99.5%，并实现非常低的阈值，约为4 keV可见反冲能量。
基于这一预期和1吨质量的活性氙，我们项目的灵敏度为0.0001事件/公斤/天，在适当的地下位置运行3年后。氙实验最近已向国家科学基金会（NSF）提出了一个初步的发展阶段，导致100公斤的单位模块的发展。
XENON is a novel liquid xenon experiment concept for a sensitive dark matter search using a 1-tonne active target, distributed in an array of ten independent time projection chambers. The design relies on the simultaneous detection of ionization and scintillation signals in liquid xenon, with the goal of extracting as much information as possible on an event-by-event basis, while maintaining most of the target active. XENON is expected to have effective and redundant background identification and discrimination power, higher than 99.5%, and to achieve a very low threshold, on the order of 4 keV visible recoil energy.
Based on this expectation and the 1-tonne mass of active xenon, we project a sensitivity of 0.0001 events/kg/day, after 3 yr operation in an appropriate underground location. The XENON experiment has been recently proposed to the National Science Foundation (NSF) for an initial development phase leading to the development of the 100 kg unit module.
