SABRE(主动背景抑制碘化钠)实验将使用一组超纯NaI (Tl)探测器阵列来搜索来自暗物质的年度调制信号,这些探测器被一个主动闪烁体所包围,以进一步降低背景。实验的第一阶段是SABRE原理验证(PoP),这是一个5公斤重的晶体探测器,在格兰萨索国家实验室(LNGS)的一个充满液体闪烁体的容器中运行。SABRE- pop装置正在进行中,目标是在2018年运行,并对晶体背景进行首次原位测量,测试否决效率,并验证SABRE概念。SABRE的第二阶段将是在lng和澳大利亚Stawell地下物理实验室(SUPL)运行的NaI (Tl)探测器双阵列。通过在两个半球设置探测器,SABRE将最大限度地减少季节性系统影响。本文介绍了SABRE活动的现状报告,以及最新的蒙特卡罗模拟结果和预期灵敏度。
The SABRE (Sodium Iodide with Active Background REjection) experiment will search for an annually modulating signal from dark matter using an array of ultra-pure NaI (Tl) detectors surrounded by an active scintillator veto to further reduce the background. The first phase of the experiment is the SABRE Proof of Principle (PoP), a single 5 kg crystal detector operated in a liquid scintillator filled vessel at Laboratori Nazionali del Gran Sasso (LNGS). The SABRE-PoP installation is underway with the goal of running in 2018 and performing the first in situ measurement of the crystal background, testing the veto efficiency, and validating the SABRE concept. The second phase of SABRE will be twin arrays of NaI (Tl) detectors operating at LNGS and at the Stawell Underground Physics Laboratory (SUPL) in Australia. By locating detectors in both hemispheres, SABRE will minimize seasonal systematic effects. This paper presents the status report of the SABRE activities as well as the results from the most recent Monte Carlo simulation and the expected sensitivity.
