Outline of Final Research Achievements

When a short bunch electron beam passes near the boundary of conductive plate, a electromagnetic radiation in terahertz frequency range, called as coherent diffraction radiation (CDR), is produced.
When a multi-bunch electron beam passes through an optical cavity which consists of mirrors with a hole, it can produce a high power terahertz radiation by coherent stacking of CDR between bunches (Stimulated radiation). We experimentally confirmed the stimulated radiation process and discussed its application for a high power terahertz source.

Academic Significance and Societal Importance of the Research Achievements

近年の先端的な加速器で得られる、低エミッタンス、短バンチ、高繰り返し、の電子ビームを用いると、穴あき共振器に損失無くビームを通過させるレイアウトが実現できるようになった。テラヘルツ帯域で回折放射による誘導放射の現象を世界で初めて実験的に示した。コンパクトERL試験加速器のような超伝導線形加速器において、誘導回折放射による大強度広帯域テラヘルツ光源が実現可能であることを示した。
