项目摘要
Dark matter is a ubiquitous yet invisible presence in our universe that makes up approximately 85% of the total mass. It plays a crucial role in how large-scale structures like galaxies form and the observed motion of stars. Its true nature remains elusive, and one compelling explanation is that is made of hitherto unknown particles which interact weakly with ordinary matter. Very sensitive experiments are required for their detection, installed deep underground to shield the much larger flux of ordinary cosmic rays. The DAMIC experiment is designed to detect nuclear and electronic recoils induced by dark matter in charge coupled devices (CCDs). Scientific CCDs are commonly used in the focal plane of astronomical telescopes for the digital imaging of faint astrophysical objects. DAMIC has pioneered their unconventional use as dark matter detectors. This award supports the participation in the DAMIC experiment of the groups at University of Chicago and University of Washington. The groups will carry out the development and testing of the CCD modules, and the installation and commissioning of DAMIC detectors in the underground laboratories toward the analysis of the first dark matter search data. As a part of the award, the groups will provide immersive research experiences, engagement of the local community and the general public, and innovative partnerships bringing science to formal and informal audiences. The nature of dark matter constitutes one of the most fundamental questions in science and the discovery of a yet unknown particle would have profound implications in our understanding of the Universe. First DAMIC CCD detectors have successfully been operated at the SNOLAB laboratory near Sudbury, Canada. A kg-size detector – DAMIC-M – is now in development and will be uniquely sensitive to light dark matter (with mass smaller than that of a proton) thanks to a novel type of CCD that allows the detection of a single ionization charge. DAMIC-M will be installed at Laboratoire Souterrain de Modane in France. In addition to the development of the CCD detectors, the US groups supported in this award are also responsible for the CCD controller electronics, and perform calibrations of electronic and nuclear recoils in the CCDs down to a threshold of a few ionization charges.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.
暗物质是宇宙中一种无处不在但看不见的物质,约占总质量的85%。它在星系等大尺度结构的形成和观测到的恒星运动中起着至关重要的作用。它的真实性质仍然难以捉摸,一个令人信服的解释是,它是由迄今未知的粒子组成的,这些粒子与普通物质相互作用很弱。它们的探测需要非常灵敏的实验,安装在地下深处,以屏蔽更大的普通宇宙射线流量。DAMIC实验旨在探测电荷耦合器件中暗物质引起的核反冲和电子反冲。科学电荷耦合器件通常用在天文望远镜的焦面上,用来对微弱的天体进行数字成像。DAMIC开创了它们作为暗物质探测器的非常规用途。该奖项支持芝加哥大学和华盛顿大学的小组参与DAMIC实验。这些小组将开发和测试ccd模块,并在地下实验室安装和调试DAMIC探测器,以分析第一批暗物质搜索数据。作为奖项的一部分,这些团体将提供身临其境的研究体验,当地社区和公众的参与,以及将科学带给正式和非正式受众的创新伙伴关系。暗物质的性质构成了科学中最基本的问题之一,而一个未知粒子的发现将对我们理解宇宙产生深远的影响。第一个DAMIC CCD探测器已经在加拿大萨德伯里附近的SNOLAB实验室成功运行。一种千克大小的探测器-DAMIC-M-现在正在开发中,由于一种新型的电荷耦合器件,它可以探测到单一的电离电荷,因此对暗物质(质量小于质子)将是唯一敏感的。DAMIC-M将安装在法国的南莫丹实验室。除了开发电荷耦合器件探测器外,该奖项支持的美国团队还负责电荷耦合器件控制器的电子设备,并对电荷耦合器件中的电子和核反冲进行校准,直到达到几个电离电荷的门槛。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智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
