The SuperCDMS Operations Program

暗物质占宇宙总质量和能量的27%，其本质是现代科学最基本的问题之一。弱相互作用大质量粒子（WIMP）是在瑞士大型强子对撞机加速器、间接探测实验和在超灵敏粒子探测器中寻找WIMP与核子相互作用的直接探测实验中寻找的一种受欢迎的暗物质候选者。SuperCDMS SNOLAB实验是一项直接探测暗物质的研究，以世界领先的灵敏度寻找质量较低的wimp，补充正在进行的全球努力。该奖项支持SuperCDMS SNOLAB实验的基础操作，因为它开始完成探测器的第一次科学数据采集。该计划包括开发可访问的分析资源，以增加本科生、研究生和博士后研究人员的培训机会。此外，计算技能将通过短期课程模块、研究项目和计划的研讨会纳入多样化的推广工作。SuperCDMS项目的目标是直接探测星系暗物质，从而解决暗物质的粒子性质，它的天体物理特性，以及它与粒子物理标准模型的关系。SuperCDMS探测器的建设即将完成，准备在位于加拿大安大略省萨德伯里的SNOLAB深地下站点安装和集成。该团队将使用先进的低温探测器，该探测器对质量在GeV/c平方质量尺度以下的暗物质粒子具有前所未有的灵敏度。先进的低温探测器将为低质量暗物质粒子提供前所未有的灵敏度，在太阳中微子核散射变得重要的暗物质-核子截面上具有最终的潜在灵敏度。除了寻找暗物质之外，该实验的声子介导探测器在宇宙学、天文学和工业领域也有应用。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。

The nature of dark matter, which makes up nearly 27% of the mass-energy content of the Universe, is one of the most fundamental questions of modern science. The weakly interacting massive particle, or WIMP, is a favored dark matter candidate sought in searches at the Large Hadron Collider accelerator in Switzerland, indirect detection experiments, and direct detection experiments that look for WIMP interactions with nucleons in ultra-sensitive particle detectors. The SuperCDMS SNOLAB experiment is a direct detection dark matter search that looks for WIMPs of lower mass with world-leading sensitivity, complementing the on-going global efforts. This award supports the base operations of the SuperCDMS SNOLAB experiment as it commences the first science data-taking of the completed detector. The program includes development of accessible analysis resources that will enhance training opportunities for training of undergraduate and graduate students and postdoctoral researchers. In addition, computational skills will be incorporated into a diverse outreach effort through short course modules, research projects, and planned workshops.The goal of the SuperCDMS project is to directly detect galactic dark matter and thus address the particle nature of dark matter, its astrophysical properties, and how it relates to the Standard Model of particle physics. The construction of the SuperCDMS detector is reaching completion in preparation for installation and integration at the deep underground SNOLAB sited in Sudbury, Ontario, Canada. The team will operate advanced cryogenic detectors that have unprecedented sensitivity to dark matter particles with masses at and below the GeV/c-squared mass scale. The advanced cryogenic detectors will provide unprecedented sensitivity to lower mass dark matter particles, with ultimate potential sensitivity to the dark matter-nucleon cross-section where solar neutrino-nucleus scattering becomes significant. Extending beyond the search for dark matter, the experiment’s phonon-mediated detectors have applications in cosmology, astronomy and industry.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.
