项目摘要
This grant will support Canadian contributions to the scientific program of the CERN-based ALPHA Collaboration. The goal of ALPHA is to measure properties of the antihydrogen atom to the highest precision possible, and to compare them to those of the ordinary hydrogen atom. These comparisons serve as tests of fundamental symmetries between matter and antimatter, and are expected to shed light on issues that rank amongst some of the greatest unsolved problems in physics.
The ALPHA Collaboration comprises approximately 50 scientists from 15 institutions in 7 countries. More than a third of those individuals come from Canadian research laboratories and universities (collectively called ALPHA-Canada), and will be supported by this grant. ALPHA-Canada has been funded by NSERC continuously since the ALPHA Collaboration was formed in 2005, and has played leading roles in many of ALPHA's most significant accomplishments. Examples of earlier high-profile milestones driven by NSERC funding include: stable (Nature 2010) and long term (Nature Physics 2011) trapping of neutral antimatter, proof of principle microwave spectroscopy (Nature 2012), and tests of charge neutrality (Nature Communications 2014 and Nature 2016).
During the tenure of our most recent three-year funding cycle, we dramatically advanced the field of antihydrogen physics. In particular, construction and commissioning of a new apparatus (ALPHA-2) enabled us to transition from what one might call “proof-of-principle” demonstrations to a robust program of precision physics. Examples of scientific milestones attained since our last SAP Project Grant application was submitted to NSERC (October 2016) include: observation of laser-induced two-photon 1S-2S transitions in antihydrogen (Nature 2017), and a subsequent 2 part-per-trillion measurement of the frequency of that transition (Nature 2018); observation of the ground hyperfine spectrum of antihydrogen (Nature 2017), and a subsequent 9 part-per-million measurement of the frequency of that transition (Nature, under review); observation of the 1S-2P Lyman-alpha transition in antihydrogen (Nature 2018), and a subsequent measurement of the fine structure and Lamb shift (Nature, under review); and laser-cooling of antihydrogen and subsequent 1S-2S spectroscopy of laser-cooled antihydrogen (manuscripts under preparation).
Further to this, we have developed and constructed yet another antihydrogen apparatus: ALPHA-g. The purpose of ALPHA-g is to enable experiments that will probe the gravitational interaction between antihydrogen and the Earth, yielding a first direct test of Einstein's Equivalence Principle in the antimatter sector. ALPHA-Canada has, is, and will play leading roles most aspects of the ALPHA-g program.
In this application, we request funding to support and exciting and highly visible three-year program of activities that will significantly advance the frontiers of precision fundamental symmetry tests with antihydrogen atoms.
这笔赠款将支持加拿大对欧洲核子研究中心的阿尔法合作科学计划的贡献。ALPHA的目标是尽可能高精度地测量反氢原子的性质,并将它们与普通氢原子的性质进行比较。这些比较是对物质和反物质之间基本对称性的检验,并有望揭示物理学中一些最大的未解决问题。
ALPHA合作由来自7个国家15个机构的约50名科学家组成。其中超过三分之一的人来自加拿大的研究实验室和大学(统称为ALPHA-Canada),并将得到这笔赠款的支持。自2005年阿尔法合作成立以来,阿尔法加拿大一直得到NSERC的资助,并在阿尔法的许多最重要的成就中发挥了主导作用。早期由NSERC资助的备受瞩目的里程碑包括:中性反物质的稳定(Nature 2010)和长期(Nature Physics 2011)捕获,原理微波光谱学的证明(Nature 2012)和电荷中性的测试(Nature Communications 2014和Nature 2016)。
在我们最近三年的资助周期中,我们极大地推进了反氢物理学领域。特别是,一个新的设备(阿尔法-2)的建设和调试,使我们能够从人们可能称之为“原理证明”的演示过渡到一个强大的精密物理程序。自我们上次向NSERC提交SAP项目资助申请以来所达到的科学里程碑示例(2016年10月)包括:在反氢中观察激光诱导的双光子1 S-2S跃迁(Nature 2017),以及随后对该转变频率的万亿分之二测量(Nature 2018);反氢的地面超精细光谱观测(Nature 2017),以及随后对该转变频率的百万分之九测量(Nature,under review); 1S-2P Lyman-alpha transition in antihydrogen(Nature 2018),并随后测量精细结构和兰姆位移。(《自然》,正在审查中);激光冷却反氢和随后的激光冷却反氢的1 S-2S光谱学(手稿正在编写中)。
除此之外,我们还开发并建造了另一个反氢装置:ALPHA-g。ALPHA-g的目的是使实验能够探测反氢和地球之间的引力相互作用,从而在反物质领域首次直接测试爱因斯坦的等效原理。ALPHA-Canada已经、正在并将在ALPHA-g计划的大部分方面发挥主导作用。
在这项申请中,我们请求资助支持令人兴奋和高度可见的三年期活动计划,这些活动将大大推进反氢原子精确基本对称性测试的前沿。
