U.S.-Korea Cooperative Research: Antiproton Studies and MassSpectroscopy

9313280 Gabrielse本奖项将资助哈佛大学物理系Gerald Gabrielse博士与韩国首尔国立大学物理系Wonho Jhe博士进行为期36个月的反质子研究和质谱合作研究项目。在这项研究中，在位于瑞士日内瓦的欧洲核子研究中心的高能加速器LEAR中产生的反质子被捕获并储存在4.2 K的热平衡状态。随后，反质子和质子的惯性质量、磁矩和其他性质可以进行比较。合作者是该提案领域中备受尊敬的研究人员。此外，Jhe博士在韩国为他的研究小组提供了生产负氢离子的设备，这种设备可以装载到反质子阱中，用于比较反质子和质子的性质。在这些实验中使用负氢离子而不是质子将大大减少许多大的实验误差。该项目与美国-韩国合作科学计划的目标相关，该计划旨在通过交流科学信息、思想、技能和技术以及通过在互惠问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学工程财团（KOSEF）的支持。该项目在美国国家科学基金（NSF）资助下为PI的研究增加了一个国际合作的维度。phy - 9122373。＊＊＊

9313280 Gabrielse This award provides funds to permit Dr. Gerald Gabrielse, Department of Physics, Harvard University, to pursue with Dr. Wonho Jhe, Department of Physics, Seoul National University, Korea, for 36 months, a program of cooperative research on antiproton studies and mass spectroscopy. In this research, antiprotons produced in LEAR, the high energy accelerator at CERN, Geneva Switzerland, are trapped and stored in thermal equilibrium at 4.2 K. Subsequently, the inertial masses, magnetic moments, and other properties of antiprotons and protons may be compared. The collaborators are highly respected researchers in the field of the proposal. In addition, Dr. Jhe has available to his research group, in Korea, facilities for producing negative hydrogen ions which can be loaded into the antiproton trap and used in comparisons of antiproton and proton properties. The use of negative hydrogen ions rather than protons in these experiments will greatly reduce a number of large experimental errors. This project is relevant to the objectives of the U.S.- Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF). This project adds an international cooperative dimension to the PI's research under NSF Grant No. PHY-9122373. ***
