提出了一种椭圆超腔,计算了椭圆超腔焦点处的光强,讨论了基于椭圆超腔技术的激光同步辐射的光子产额和辐射功率.结果发现:当椭圆超腔镜壁的反射率为99·99%时,椭圆超腔焦点处的光强可以达到入射光强I0的5000倍;利用3·5GeV电子束与在椭圆超腔焦点处的激光束垂直散射可以获得能量10·975MeV的高亮度γ射线,其光子产额和辐射功率将比电子束与单束激光垂直散射时产生的光子产额和辐射功率高2·5×107倍. An ellipse supercavity is proposed to calculate the light intensity at the focal point of elliptical supercavity and the photon yield and radiation power of the laser synchrotron radiation based on oval hyper cavity technique are discussed.The results show that when the reflectance Is 99.99%, the intensity of the elliptical superfocal cavity can reach 5000 times of the incident light intensity I0. Using the 3.5GeV electron beam and the vertical scattering of the laser beam at the focal point of the elliptical cavity can obtain the energy of 10.975MeV High-brightness gamma rays, whose photon yield and radiant power will be 2.5 × 107 times higher than the photon yield and radiant power generated when the electron beam and the single-beam laser scatter vertically.
