XENON暗物质计画

XENON暗物质计画^[1]是一个建构新一代暗物质探测器的计画。其实验仪器是利用液态氙作为靶材去探测大质量弱相互作用粒子（英文叫做Weakly Interacting Massive Particle，简称WIMP）。这个合作计画是由哥伦比亚大学的天文物理的埃琳娜·阿普罗（Elena Aprile）所推动。

XENONnT 探测器

XENONnT探测器是最新一代的液氙暗物质直接探测器，位于意大利格兰萨索国家实验室（INFN Laboratori Nazionali del Gran Sasso）。其共有8.5吨液氙，其中有效探测质量5.9吨。基于更大的有效探测质量、更低的电子反冲本底、更久的电子漂移寿命，XENONnT探测器相比于上一代的XENON1T探测器有预期一个数量级以上的对于WIMP暗物质的限制的提升。^[2]

2023年，XENONnT发布了基于第一批核反冲数据的对于5-500GeV WIMP暗物质的限制^[3]。
