KAKENHI (Grants-in-Aid for Scientific Research) 2

  1. 放射光の位相構造制御法の開発

    Grant number:20H00164  2020.4 - 2023.3

    加藤 政博

      More details

    Authorship:Coinvestigator(s) 

    高エネルギー自由電子から放射される光(電磁波)は電波からガンマ線まで全ての波長域に及び、高強度で指向性に優れていることからレーザーと並んで研究用光源として広く利用されている。本研究では、加速器の技術を用いて荷電粒子の運動を制御することで、放射光の波の時間構造や空間構造を制御する新しい光ビームの発生法を開拓しその利用の可能を探る。

  2. 小型光源リングでの極短周期アンジュレータ実用化とそれに最適化した光源リングの設計

    Grant number:19H04401  2019.4 - 2022.3

    Authorship:Coinvestigator(s) 

    本研究では,既存の低エネルギー小型電子蓄積リングに極短周期アンジュレータを設置して,実際に発生するアンジュレータ放射光のスペクトルを測定することにより,極短周期アンジュレータがこのような小型電子蓄積リングに於ける高エネルギー放射光源として有用であることを実証する。
    上記と平行して,極短周期アンジュレータに最適化した光源リングの設計を行う。非常に狭いギャップで動作する極短周期アンジュレータの実用性が,上記の実証を達成することにより,低エネルギーリングにおいても10keVクラスのアンジュレータ硬X線生成が可能な高輝度光源の設計・開発に新たな指針を与えると考える。
