This award supports the base research program of the SuperCDMS SNOLAB experiment that will address one of the most fundamental questions of modern science—the nature of dark matter. SuperCDMS explores a lower mass dark matter parameter space with world-leading sensitivity that is complementary to on-going searches at the Large Hadron Collider, indirect detection experiments, and direct detection experiments like LZ and XENONnT that will search for heavier-mass dark matter. The SuperCDMS SNOLAB experiment will have a broad impact that 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. The SuperCDMS Collaboration has a long history of outreach with a strong focus on engaging students from underrepresented groups at all educational levels. This award will enable the development of accessible analysis resources that will significantly increase the number of undergraduates involved in SuperCDMS science analysis and in particle physics analyses in general. In addition, SuperCDMS will leverage the SNOLAB outreach team by increasing participation in tour groups and SNOLAB on-site exhibits, and partner with the Colegio de F´ısica Fundamental e Interdiciplinaria de las Am´ericas (COFI) in bringing dark matter themed educational efforts to student and public audiences in Puerto Rico.The goal of the SuperCDMS Collaboration is to directly detect galactic dark matter and, in so doing, address the following questions: what is the particle nature of dark matter, what are its astrophysical properties, and how does it relate to the Standard Model? In pursuit of this goal, the Collaboration is in the process of constructing a new experiment, SuperCDMS SNOLAB, equipped with advanced cryogenic detectors that have unprecedented sensitivity to dark matter particles with masses at and below the GeV/c-squared scale, with an ultimate potential sensitivity down to dark matter-nucleon cross sections where solar neutrino-nucleus scattering becomes significant (the so-called “neutrino fog”). The experiment will be sited in SNOLAB, Sudbury, Canada.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.

该奖项支持SuperCDMS SNOLAB实验的基础研究计划，该计划将解决现代科学最基本的问题之一-暗物质的性质。SuperCDMS探索了一个具有世界领先灵敏度的低质量暗物质参数空间，这与大型强子对撞机正在进行的搜索，间接探测实验以及LZ和XENONNT等直接探测实验是互补的，这些实验将搜索更大质量的暗物质。SuperCDMS SNOLAB实验将产生广泛的影响，超出了对暗物质的研究。该实验的声子介导探测器在宇宙学，天文学和工业中有应用。这一努力将为培养本科生、研究生和博士后研究人员提供机会。SuperCDMS协作有着悠久的推广历史，重点是吸引各级教育中代表性不足群体的学生。该奖项将使可访问的分析资源的开发，这将显着增加参与SuperCDMS科学分析和粒子物理分析的本科生人数。此外，SuperCDMS将通过增加对旅游团和SNOLAB现场展览的参与来利用SNOLAB外展团队，并与Colegio de F sica Fundamental e Interdiciplinaria de las Am ericas（COFI）合作，为波多黎各的学生和公众带来以暗物质为主题的教育工作。SuperCDMS协作的目标是直接探测银河系暗物质，并在这样做的过程中，解决以下问题：暗物质的粒子性质是什么，它的天体物理特性是什么，它与标准模型有什么关系？为实现这一目标，协作机制正在建造一个新的实验，即超级CDMS SNOLAB，该实验配备了先进的低温探测器，对质量等于或低于GeV/c平方尺度的暗物质粒子具有前所未有的灵敏度，最终可能灵敏到暗物质-核子横截面，在那里太阳中微子-核散射变得显著（所谓的“中微子雾”）。该实验将设在加拿大萨德伯里的SNOLAB。该奖项反映了NSF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。
