Outline of Final Research Achievements

A tunable quasi-monochromatic X-ray/gamma-ray is useful for fundamental nuclear experiments using high energy photon, industrial non-destructive imaging applications, medical angiography, and so on. Especially in such practical applications, reduction of radiation exposure is important. In order to increase the ratio of useful photon quanta to the total photon quanta, the bandwidth of the X-ray/gamma-ray should be narrowed. A laser Compton scattering (LCS) X-ray or gamma ray which is generated through Compton scattering of laser light on high-energy relativistic electron can generate high-flux X-ray/gamma-ray beam with narrow bandwidth. However, the direction of photon beam is limited to the direction of electron beam.
In this work, a new method to control direction of photon beam using non-spherical mirror and multi pole wigglers was tested. An 1/10 scale of non-spherical mirror was fabricated and several real-scale models for specific application were designed.
