摘要
如今存在宇宙中存在暗物质的令人信服的证据。已达成普遍共识：需要一种方向灵敏的探测器，以互补方法确认传统搜寻中发现的候选者，并最终将其灵敏度扩展到中微子诱导本底极限之外。我们在此提议使用基于核乳胶的探测器来测量 WIMP 诱导的核反冲方向。具有纳米级颗粒的核乳胶薄膜的生产已确立。若干测量活动已证明检测此类乳胶薄膜中低能离子留下的亚微米径迹的能力。采用全自动化光学显微镜的创新分析技术使得能够实现低至一百纳米路径长度的径迹重建，并且有良好的前景进一步超越该极限。我们提议的探测器概念预见使用一堆核乳胶薄膜，周围有环境放射性屏蔽，放置于赤道望远镜上以抵消地球自转的影响，从而保持探测器朝向银河系 WIMP 预期方向的固定方位。我们报告了质量一公斤的试点实验的进度表和成本估算，旨在六年时间尺度上提供首批结果。
