Development of a High Energy Gamma-ray Beam via Inverse Compton Scattering of Soft X-rays

Abstract

We aim to develop a novel technique to produce a high energy γ-ray beam of several GeV by adopting inverse Compton scattering of soft X-rays at an electron storage ring. Now an experimental project to demonstrate such a beam is being advanced at NewSUBARU by using X-rays from a short undulator and reflecting it backwardly with a Mo/Si multi-layer mirror. It will open up a way to construct new γ-ray sources at the next generation rings and to carry out new photoproduction experiments for the studies of heavy hadrons.
