AI总结:

DarkSide-20k实验旨在通过双相液氩时间投影室探测暗物质WIMP类粒子,利用硅光电倍增管阵列进行光读出,计划于2026年底开始数据采集。

摘要:

DarkSide-20k实验代表全球氩暗物质合作计划的当前目标。结合之前基于氩的探测器经验,以及在DUNE项目中开发的大体积膜低温箱的知识,社区现在正在建造一个双相液氩时间投影室(LAr-TPC),配备硅光电倍增管(SiPM)阵列用于光读出。实验的主要目标是发现或扩展当前对暗物质WIMP类粒子搜索的灵敏度限制。目前,实验已进入建设阶段,外部低温箱正在意大利劳伦利纳国家实验室(LNGS)安装。探测器建设将随后进行,预计2026年底开始数据采集。本文将介绍DarkSide探测器和目标,并报告LNGS地下基础设施的建设进展。最后,将集中于当前硅光探测器大规模阵列的活动,这些探测器是探测器光读出系统建设的基础。

英文摘要:

The DarkSide-20k experiment represents the present goal of the Global Argon Dark Matter Collaboration program. Bringing together the experience from previous argon-based detectors, as well as the knowledge gained on large volume membrane cryostats developed within the DUNE program, the community is now building a dual-phase LAr-TPC equipped with SiPM arrays for light readout. The main goal of the experiment is to discover or to extend the current sensitivity limits on the search for dark matter WIMP-like particles. Currently, the experiment has entered the construction phase and the external cryostat is being put in place at Laboratori Nazionali del Gran Sasso (LNGS), Italy. Detector construction will follow, and data taking is expected to start in late 2026. This contribution will introduce the DarkSide detector and goals, and it will report on the ongoing construction of the underground infrastructure at LNGS. Finally, it will concentrate on the current activities on large arrays of silicon light detectors, that are at the base of the construction of the detector light readout system.
