| < < | A high intensity photon beam has various applications in advanced accelerators. Optical cavity is an unique system to realize such high intensity photon beam at a high repetition rate. Especially the laser-Compton scheme, which uses the high intensity photon produced in the optical cavity as a target of a high-energy electron beam to produce energetic photon, is a promising technique. At the ILC, it can be used for a polarized positron source, a photon collider system, beam size and polarization diagnostics. It also is the heart of the system in compact Compton light sources recently proposed in LAL and KEK. The goal of this project is to further push the technical limits in the existing optical cavity system. | |||||||
| > > | High intensity photon beams have various applications in advanced accelerators, from medical imagery (X-rays) to high energy physics (polarized positron beams, photon colliders) passing by nuclear physics (fundamental and applied). They can be obtained by laser-Compton backscattering off electrons, the main advantage being the possibility to produce high flux monochromatic photon beams. In this context, an optical cavity is a unique system to reach the requested laser beam power at high repetition rates. LAL and KEK are developing such light sources and are trying to push forward the technical limits to increase the maximal power stored in these optical cavities. | |||||||
