Observations indicate that 85% of the matter in the Universe is not made of normal atoms but must be otherwise undetected elementary "dark matter" particles that do not emit or absorb light. Remarkably, particle physics theories proposed for other reasons predict the existence of Weakly Interacting Massive Particles (WIMPs) with just the right properties to be this dark matter. If WIMPs are the dark matter, they may be detectable when they scatter in Earth-based detectors. Direct detection of WIMP dark matter would solve a fundamental mystery in particle physics and cosmology, providing a unique window to learning about the primary matter constituents of the Universe and of physics beyond the Standard Model of particle physics. Over the past three years, the SuperCDMS collaboration has led the field in the search for low-mass dark matter. The most recent results from CDMSlite reached an energy threshold for electron recoils as low as 56 eV. These results excluded new parameter space for the dark matter-nucleon spin-independent cross section for dark matter masses between 1.6 and 5.5 GeV/c2. This project will focus on better understanding the response of the signal detectors in a push to make the SuperCDMS yet more sensitive.The SuperCDMS SNOLAB experiment will have a broad impact which extends beyond the search for dark matter. The experiment's phonon-mediated detectors have applications in cosmology, astronomy and industry. This effort will contribute opportunities for training of undergraduate and graduate students and postdoctoral researchers. SuperCDMS will engage in education and outreach at local institutions and will coordinate outreach at SNOLAB and the Sanford Underground Research Facility (SURF) in South Dakota to increase the broader impact with a focus on secondary education. This award will support participating in SNOLAB-hosted teacher workshops, modifying and providing middle school dark matter education modules to U.S. educators, and maintaining SuperCDMS-related outreach materials for SNOLAB in Canada and SURF. Existing alliances will enable out-reach to Sudbury First Nations communities. This effort will also support post-graduate education and outreach to underrepresented groups.In order to maximize the science output of SuperCDMS SNOLAB, detailed understanding of the response of detectors to potential signals and backgrounds is required. Measurements at two underground facilities (NEXUS at Fermilab and CUTE at SNOLAB) will characterize and calibrate pre-production SuperCDMS SNOLAB detectors and the first production SuperCDMS SNOLAB towers, with supporting measurements from small devices at university test facilities. Resulting data will allow energy scale calibration, measurements of background levels, understanding of the detailed phonon and electron physics of the detectors, development of improved background-rejection techniques, validation and tuning of Detector Monte Carlo, and optimization of SuperCDMS SNOLAB operational parameters. These data should also provide a dark matter search with world-leading sensitivity.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

观测表明，宇宙中85%的物质不是由普通原子组成的，而是由未被探测到的基本“暗物质”粒子组成的，它们既不发射光，也不吸收光。值得注意的是，由于其他原因提出的粒子物理理论预测了弱相互作用大质量粒子（wimp）的存在，这些粒子的性质正好与暗物质的性质相符。如果wimp是暗物质，那么当它们在地球上的探测器散射时，它们可能会被探测到。直接探测WIMP暗物质将解决粒子物理学和宇宙学中的一个基本谜团，为了解宇宙的主要物质成分和粒子物理学标准模型之外的物理学提供一个独特的窗口。在过去的三年里，超级cdms合作在寻找低质量暗物质方面一直处于领先地位。CDMSlite的最新结果达到了低至56 eV的电子反冲能量阈值。这些结果排除了暗物质的新参数空间——暗物质质量在1.6和5.5 GeV/c2之间的与核子自旋无关的截面。该项目将集中于更好地理解信号探测器的响应，以推动超级cdms更加敏感。超级cdms SNOLAB实验将产生广泛的影响，其影响将超出对暗物质的搜索。该实验的声子介导探测器在宇宙学、天文学和工业中都有应用。这项工作将为培养本科生、研究生和博士后研究人员提供机会。SuperCDMS将参与当地机构的教育和推广活动，并将协调SNOLAB和南达科他州桑福德地下研究设施（SURF）的推广活动，以增加对中等教育的广泛影响。该奖项将支持参加SNOLAB主办的教师研讨会，修改并向美国教育工作者提供中学暗物质教育模块，并为加拿大和SURF的SNOLAB维护与supercdms相关的推广材料。现有的联盟将有助于向萨德伯里原住民社区伸出援助之手。这项工作还将支持研究生教育和向代表性不足的群体伸出援手。为了最大限度地提高SuperCDMS SNOLAB的科学输出，需要详细了解探测器对潜在信号和背景的响应。在两个地下设施（费米实验室的NEXUS和SNOLAB的CUTE）的测量将表征和校准预生产的SuperCDMS SNOLAB探测器和第一个生产的SuperCDMS SNOLAB塔，并在大学测试设施的小型设备上进行支持测量。所得数据将用于能量刻度校准、背景电平测量、了解探测器声子和电子物理的详细情况、改进背景抑制技术的开发、探测器蒙特卡罗的验证和调谐以及SuperCDMS SNOLAB操作参数的优化。这些数据也将提供具有世界领先灵敏度的暗物质搜索。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
