| Outline of Final Research Achievements |
This study is concerned with club collisional laser Compton scattering, in which a tilt angle is given to the electron beam in laser Compton scattering, which produces X-rays through the interaction between the electron beam and the laser pulse, to achieve a luminosity close to that of a head-on collision. At present, we have succeeded in generating high-quality laser pulses of millijoule picoseconds as a colliding laser system by constructing a ring-shaped regenerative amplifier using thin-disk Yb:YAG. Note that the electron-laser collision timing control is still insufficient. In the future, we may use two servo systems with an RF signal generator as a master oscillator or a single laser oscillator and separate the pulses to make them jitter-free.

| Academic Significance and Societal Importance of the Research Achievements |
レーザーコンプトン散乱X線源は放射光施設に匹敵する、高品質・高強度のエネルギー可変X線発生を実用化できる手法である．本研究において，これまで十分な出力が得られないという難点を克服するための技術を極め，レーザーの高出力化，電子ビームの高品質化等を通じ，クラブ衝突スキームによって2桁以上の共同増強を実現できる技術的見通しを得ることができた．これにより，世界各地で開発が進められてきている当該技術について非常に大きなインパクトを与えることができるようになった．近くこの開発で達成された技術をKEK－LUCXにおいて実用し，短時間でのイメージングができるようになると期待される．
