提出了一种由一对抛物面构成的超腔的技术方案,计算了超腔汇聚点处的总光子密度.利用康普顿散射理论对基于抛物面超腔的激光同步辐射及其光子产额进行了讨论和计算.结果表明:当超腔镜面的反射率等于99.99％时,在超腔碰撞点处的总光子数密度大约是初始激光束在碰撞点处光子数密度的5 000倍,对应康普顿垂直散射的光子产额大约是电子束与初始激光束在碰撞点处发生康普顿垂直散射时的5 000倍.

A technical scheme of super-cavity with two parabolic mirrors is presented.The total photon density at the collision point of parabolic super-cavity is computed.By using the Compton scattering theory,the high brightness laser synchrotron source based on the parabolic super-cavity,including photon yield are discussed and calculated.The results show that when the reflectivity of parabolic mirror is equal to 99.99％,the total photon density at the collision point after infinite reflection is about 5 000 times higher than the photon density of the input laser beam at the collision point,and the photon yield of corresponding Compton vertical scattering is about 5 000 times higher than the photon yield of Compton vertical scattering between electron beam and input laser beam at the collision point.
