プラズマ利用ミリ波・サブミリ波帯パルス電磁波放射入門 4.サブナノ秒領域パルス電子ビームの生成と電磁波発生

抄録

Basic interactions between an intense electron beam and a cavity are reviewed. An intense electron beam with strong self-field can be compressed using coaxial cavities with decreasing lengths. An intense electron beam with subnanosecond duration is available by this scheme.
