提出了一种超腔的新技术方案，利用康普顿散射理论计算了基于超腔技术的激光同步辐射(LSS)波长以及单个电子的光子产额和辐射功率，讨论了电子束品质和激光功率损耗对激光同步辐射的总光子产额和总辐射功率的影响。结果发现,利用3.5 GeV电子束和远红外激光进行康普顿垂直散射可以获得能量10.975 MeV的γ射线，单个电子产生的光子产额与激光功率和入射波长成正比，与光束的截面积成反比。单个电子的辐射功率与激光功率和Lorentz因子的平方成正比，与光束的截面积成反比。

The novel technical scheme of super cavity is proposed. Using Compton scattering theory, the high brightness laser synchrotron source (LSS) based on the technique of super cavity, including radiation wavelengths, photon yield and radiant power, are calculated and discussed. The effects of the electron beam quality and the laser power loss on the photon yield and radiant power of laser synchrotron source are discussed. The results show that the γ-ray with energy up to 10.975 MeV are expected to be produced by Compton vertical scattering of far-field infrared laser photons on the 3.5 GeV electrons bunches, the photon yield of a single electron are direct proportion to the power and wavelength of laser, and inverse proportion to the sectional area of laser beam. The radiant power of a single electron is direct proportion to the power of laser and square of Lorentz factor, and inverse proportion to the sectional area of laser beam.
