在直接暗物质探测实验中测量年度调制不仅证明了WIMP的存在,而且还可以告诉我们更多关于它们与标准物质的相互作用,甚至可能是它们在晕中的密度和速度。这种调制已经在NaI(Tl)晶体中通过DAMA/LIBRA实验测量。然而,解释为WIMP信号是有争议的,由于其他实验的结果相矛盾。SABRE实验的目的是阐明这一争议,通过检测年度调制在同一目标材料的DAMA与双探测器在LNGS在意大利和SUPL在澳大利亚。在北方和南半球的两个地点可以验证其他季节效应或地点是否对测量产生影响,从而减少系统效应。本文将对实验设计、主要用于高纯晶体生长的原理验证阶段的现状以及未来计划进行概述。
Measuring an annual modulation in a direct Dark Matter detection experiment is not only a proof of the existence of WIMPs but can also tell us more about their interaction with standard matter and maybe even their density and velocity in the halo. Such a modulation has been measured by the DAMA/LIBRA experiment in NaI (Tl) crystals. However, the interpretation as WIMP signal is controversial due to contradicting results by other experiments. The SABRE experiment aims to shed light on this controversy by detecting the annual modulation in the same target material as DAMA with twin detectors at LNGS in Italy and at SUPL in Australia. The two locations in the northern and southern hemisphere allow to verify if other seasonal effects or the site have an influence on the measurement, thus reducing systematic effects. This paper will give an overview on the experimental design, the current status of the proof of principle phase mainly devoted to high-purity crystal growing, and an outlook on future plans.
