Compton散乱X線源へのレーザー周回システムの適用

We are developing a compact monochromatic hard-X-ray source for medicine.Monochromatic hard-X-ray is generated by inverse Compton scattering between laser pulses and electron beams. Laser circulation system is adopted to amplification of X-ray yield.In the proof-of-principle experiment with 25mJ/pulse Q-switch Nd:YAG laser (2nd harmonic,l=532nm), the laser intensity became larger than 10 times. Then, the X-ray yield will increase up to at least 10^9photons/sec. The method of laser beam position control at collision point is to be established. We designed laser circulation system for the prototype devise.This design is based on the proof-of-principle experiment.第7回応用加速器・関連技術研究シンポジウ
