This project has been continued for last three years, and this fiscal year is the time for summarizing the project. The research subjects included in this project were carried out around the following key subjects : 1. The interaction of large amplitude electron plasma wave with particles 2. The controlling of distribution of electron function 3. New trend of particle accelerator and plasma lens using plasmas, and 4. Current drive and additional heating in plasma. This project provide an opportunity for obtaining detailed understanding on the basic phenomena related to the above-mentioned fields, and for consolidating a base to carve out new fields in plasma physics.In order to realize the goal of this project, meetings and discussions were held mainly concerning about : (1) the excitation of large amplitude wave with high efficiency and its measuring methods and the particle trapping of wave (Amagishi, Mase, Hatakeyama, Komori and Hatori, et al) ; (2) the acceleration of ultrahigh ene … More rgy particles and beam focusing (Ogata, Yoshida, Shibata and Nakajima, et al) ; (3) accelerators using microwave (Nishida, Yatsuzuka, Sugihara and Yugami, et al) ; (4) large scale laser accelerators (Mima, Kitagawa, Sakai and Takeuchi, et al) ; and (5) the current drive in plasma (Terumichi and Yasaka, et al).Considering the establishment of the Japan Atomic Energy Research Institute in Kansai, we organized a Joint Conference with JAREI in the latter of this fiscal year. The establishment of this institute is one of the great advancements of our research project because the main tasks in this institute are the development and applications of laser accelerators. After this conference, our own conference was held, and both of them were finished with great accomplishment. This project was finished in this fiscal year, but the members of this project have promised to continue changing information frequently and keeping contacting closely in order to make further progress on present research Less

这个项目已经持续了三年，本会计年度是项目总结的时间。本项目所包含的研究课题围绕以下几个重点课题展开：大振幅电子等离子体波与粒子的相互作用。电子函数分布的控制3 .使用等离子体的粒子加速器和等离子体透镜的新趋势；等离子体中的电流驱动和附加加热。本项目为详细了解上述领域的基本现象提供了机会，为开拓等离子体物理新领域奠定了基础。为了实现本项目的目标，会议和讨论主要涉及：(1)高效的大振幅波激发及其测量方法和波的粒子捕获（Amagishi, Mase, Hatakeyama， Komori and Hatori等）；(2)超高高能粒子的加速和光束聚焦（Ogata, Yoshida， Shibata and Nakajima等）；(3)微波加速器（Nishida, Yatsuzuka， Sugihara和Yugami等）；(4)大型激光加速器（Mima, Kitagawa， Sakai和Takeuchi等）；(5)等离子体中的电流驱动（Terumichi and Yasaka, et al）。考虑到在关西设立日本原子能研究所，我们在本财政年度末与JAREI举行了联合会议。这个研究所的建立是我们研究项目的一个重大进展，因为这个研究所的主要任务是激光加速器的开发和应用。这次会议之后，我们自己的会议也开了，两次会议都圆满结束了。这个项目是在本财年完成的，但是这个项目的成员承诺会继续频繁地更新信息，保持密切的联系，以便在目前的研究中取得进一步的进展
