The Production and Study of Cold Antihydrogen

该项目的重点是反氢冷原子的生产和1 S-2S跃迁频率的最终高精度光谱测量。 实验利用了一个嵌套的潘宁阱，在这个阱中，冷的正电子和反质子可以被允许联合收割机结合，产生的氢原子然后被困在同一个磁结构中，在那里它们可以被光谱分析。 实验将在欧洲核子研究中心的反质子减速器（AD）设施进行，这是一项国际合作的一部分，该合作将涉及美国哈佛大学和NIST的研究小组，来自马克斯普朗克量子光学研究所、核物理研究所和德国波恩大学以及荷兰阿姆斯特丹大学的研究小组。 AD建设的资金由日本捐款和CERN提供。 预计与实验相关的技术困难将促使开发新的工具和技术，这些工具和技术可以在物理和化学的许多领域得到利用，数学和物理科学局的多学科活动办公室（OMA）提供了部分支持。

This project focuses on the production of cold atoms of antihydrogen and the ultimate high-precision spectroscopy measurement of the 1S-2S transition frequency. The experiments utilize a nested Penning trap in which cold positrons and antiprotons can be allowed to combine, and the resulting atoms of hydrogen then trapped within the same magnetic structure, where they can be spectroscopically analyzed. The experiments will be performed at the Antiproton Decelerator (AD) facility at CERN as part of an international collaboration that will involve research groups from Harvard University and NIST in the United States, from the Max Planck Institut fur Quantenoptik, the Institut fur Kernphysik, and the University of Bonn in Germany, and from the University of Amsterdam in Holland. Funding for the AD construction is provided through a Japanese contribution and through CERN. It is expected that the technical difficulties associated with the experiment will prompt the development of new tools and techniques that can find utilization in a number of areas in physics and chemistry, and partial support is provided by the Office of Multidisciplinary Activities (OMA) in the Directorate for Mathematical and Physical Sciences.
