A Soft X-Ray and Gamma-Ray Source Using Laser and Electron Beams

摘要

Soft X-ray and gamma-ray beam sources are developed by using laser and high-energy electron beams. Laser plasma soft X-ray source is a cryogenic Xe target irradiated by a high average power (> 100 W) and high peak power (30 MW, 0.3 J/10 ns) laser. A conversion efficiency from the laser energy to the soft X-ray (70 to 200 eV) energy of 22% was achieved. Laser Compton gamma-ray source on a synchrotron radiation facility, New SUBARU, is a new quasi-monochromatic high-energy photon beam. The world's highest class gamma-ray flux of more than 10~6 photons/s is generated at a photon energy range of 6 to 17 MeV.
