Research Abstract

This project aims at making a high energy mono-energetic photon beam possible by reflecting synchrotron radiation X-ray to have Compton backward scattering from circulating 8 GeV electrons in the SPring-8 storage ring. The first thing to do is to reflect synchrotron radiation X-ray by 180 degrees. Second, the reflected X-ray has to be controlled to give a head-on collision with 8 GeV electrons circulating in the ring. Then finally, we will be able to observe high energy mono-energetic photons produced by means of Compton backward scattering of the reflected X-ray from the 8 GeV electrons.
It takes more time to attain the final goal. And we are still at the first stage. In the present project we succeeded in measuring 180-degree reflected 9.1 keV X-ray of synchrotron radiation, employing a Si(008) Bragg reflector.
