"Atomic Physics of Highly Charged Ions"

作为原子物理领域的国家项目，高电荷离子（hci）的原子物理研究已经进行了三年的深入研究。本研究项目包括两个主要课题：A01 hci光谱，A02 hci与物质的相互作用。为了进一步推进这一研究项目，需要开发和构建用于生产hci的新型离子源。2001年，世界上最好的电子束离子源/阱在中国电子通信大学建成，具有300 keV，300 ma的连续电子束。预计该源可以产生裸铀离子。目前，光Ba、Xe离子等hci的各种光谱研究正在进行中。在A02中，两个电子回旋共振离子源分别安装在东京都大学和东京大学核研究所。光源分别有三条束流线，用于进行HCI与物质相互作用的各种实验研究。1996年9月，我们在大宫举办了“hci物理学国际会议”，会上发表了关于这个项目的40多篇论文。

As a national project in Atomic Physics Area, intensive study on the Atomic Physics of Highly Charged Ions (HCIs) has been performed for three years. This research program includes the following two main subjects :A01 Spectroscopy of HCIs,A02 Interaction of HCIs with matters.To progress the research project, it is needed to develop and construct the new ion sources for the production of HCIs.In A01, the world-best Electron Beam Ion Source/Trap has been constructed in University of Electro-Communications, with the CW electron beam of 300 keV,300mA.It is expected that the source can produce bare U ions. At present, various spectroscopic studies of HCIs such as bare Ba, Xe ions are in progress.In A02, two Electron Cyclotron Resonance Ion Sources have been installed at Tokyo Metropolitan University and Institute for Nuclear Study, University of Tokyo. The sources have respectively three beam lines to perform various kinds of experimental researches for HCI interaction with matters.In September 1996, we have organized "International Conference on the Physics of HCIs" at Omiya, where more than forty papers in this project has been presented.
