This project aims to develop ultra-sensitive detector technology essential for SABRE, a world-wide experiment with detectors in both the Northern and Southern Hemispheres which are operated together to directly detect the dark matter halo of our Milky Way galaxy. Dark matter makes up nearly five times more mass in the universe than everything we can see, yet it has never been detected in the laboratory. SABRE South will be installed in the Stawell Underground Physics Laboratory in a goldmine in Victoria, Australia. Dark matter is not the only thing SABRE can detect. The project will measure all possible types of naturally occurring radiation, from space, the surrounding rock, and the detectors themselves, that can blind SABRE to dark matter.

该项目旨在开发SABRE所必需的超灵敏探测器技术，SABRE是一项世界范围的实验，北方和南半球的探测器一起运行，直接探测我们银河系的暗物质晕。暗物质在宇宙中的质量几乎是我们所能看到的一切的五倍，但它从未在实验室中被发现。SABRE South将安装在澳大利亚维多利亚金矿的斯塔韦尔地下物理实验室。暗物质并不是SABRE唯一能探测到的东西。该项目将测量所有可能的自然辐射类型，包括来自太空、周围岩石和探测器本身的辐射，这些辐射可以使SABRE对暗物质视而不见。
