摘要
DEAP-3600 实验位于安大略省萨德伯里的 SNOLAB 地下 2 公里处。它是一个单相探测器，旨在搜寻暗物质粒子与 1000-kg 基准质量液态氩靶内的相互作用。第一代原型探测器（DEAP-1）拥有 7-kg 液态氩靶质量，展示了高水平的脉冲形状甄别（PSD）能力，用于减少 / 本底，并帮助开发了低放射性技术以减轻与表面相关的 本底。DEAP-3600 探测器的建设已接近完成，调试工作将于 2014 年开始。其对弱相互作用大质量粒子（WIMPs）与核子自无关散射的目标灵敏度为 10 cm，这将使在 100 GeV WIMP 质量下的灵敏度较当前搜寻提高一个数量级。本文概述了 DEAP-3600 项目的现状，并讨论了未来多吨级实验 DEAP-50T 的计划。
