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

小行星9313280 该奖项提供资金，允许哈佛大学物理系的Gerald Gabrielse博士与韩国首尔国立大学物理系的Wonho Jhe博士进行为期36个月的反质子研究和质谱学合作研究计划。 在这项研究中，在瑞士日内瓦CERN的高能加速器LEAR中产生的反质子被捕获并在4.2 K的热平衡下储存。 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备受尊敬的研究人员。 此外，Jhe博士还向他在韩国的研究小组提供了生产负氢离子的设施，这些负氢离子可以装入反质子阱，并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一些大的实验误差。 该项目与美国的目标有关- 韩国合作科学计划，旨在通过科学信息，思想，技能和技术的交流以及通过互利问题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。 韩国对该项目的参与得到了韩国科学和工程基金会的支持。 这个项目增加了国际合作的层面，PI的研究下，美国国家科学基金会资助号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. ***
