摘要
激光康普顿散射(Laser Campton Scattering, LCS)光源,是一种基于相对论电子束与激光光子相互作用的新型X-ray或Gamma-ray光源。它具有能量高、波长短、脉冲快和峰值亮度高的特性,已成为国际先进光源技术的重要选项之一。本文介绍了激光康普顿散射光源的产生原理、国内外发展现状以及目前国际上运行和在建的激光康普顿散射光源装置,其中重点介绍了上海光源二期正在建设的上海激光电子伽马源(Shanghai Laser Electron Gamma Source, SLEGS)装置,以及在这一光源装置上可以开展的核物理、核天体物理、核废料处理及核医学应用等研究。随着上海软X射线自由电子激光试验装置(Soft X-ray Free Electron Laser, SXFEL)升级为用户装置,以及未来十三五国家重大科技基础设施-硬X射线自由电子装置(Shanghai HIgh repetition rate XFEL aNd Extreme light facility,SHINE)的建设完成,基于直线电子加速器(LINear ACcelator, LINAC)的康普顿散射光源的伽马能量将会达到GeV量级的高能量。超短脉冲、高极化度、高通量的激光康普顿散射光源将迎来新的发展机遇,基于康普顿伽马光源的核物理、天体物理、粒子物理及应用基础研究也必将迈上一个新台阶。
Laser Campton Scattering-LCS source is a new type X-ray or Gamma-ray light source based on the interaction of the relativistic electron beam with the laser photon. It has the characteristics of high energy, short wave length, fast pulse and high peak brightness, and has become one of the important options of advanced light source technology in the world. This paper introduces the production principle of laser Compton scattering light source, the historical development in China and international laboratory, and the laser Compton scattering light source facility currently running and under construction internationally. The Shanghai Laser Electron Gamma source(SLEGS) is under construction in Shanghai Light Source PHASE II project, the research on nuclear physics,nuclear astrophysics, nuclear waste disposal and nuclear medicine applications that can be carried out on this gamma source. With the upgrade of the Soft X-ray Free Electron Laser(SXFEL) to a user facility, and the Shanghai HIgh repetition rate XFEL aNd Extreme light facility(SHINE)-Large-scale scientific facility of the 13 th FiveYear Plan will be completed in the future. The gamma energy of the Compton scattering source in LINear ACcelator(LINAC) will reach the GeV energy. Ultra-short pulse, high polarization, high-flux laser Compton scattering light source will usher in new development opportunities. The study of nuclear physics, astrophysics, particle physics and applied basic research based on Compton Gamma source will also reach a new level.
