摘　　要：基于高亮度电子束与超短强激光相互作用的逆康普顿散射X/γ射线源具有单色性好、能量可调、偏振可控等特点,在核安全及核安保领域具有广泛的应用前景。清华大学将研制国际上首套能量达MeV的紧凑准单能伽马源装置并开展包括先进辐射成像、基于核共振荧光的物质分析检测等应用工作。给出该光源设计方案,以及针对其关键性能指标进行的优化及光源最终性能指标。目前已完成光源的设计,正在进行部件的加工采购,预计将于2023年启动装置的安装调试工作,于2025年完成项目的调试和验收。Inverse Compton scattering X/gamma-ray source can produce quasi-monochromatic, continuously tunable, high brightness, small spot size, polarization precisely controllable, and ultrashort(ps or sub-ps) X-ray pulse in the energy regime ranging from tens keV to several MeV or even higher. Recently a 0.2-4.8 MeV quasimonochromatic compact gamma-ray source with high peak spectral density based on the inverse Compton scattering has been proposed in the Department of Engineering Physics, Tsinghua University. This type of compact gamma-ray source will be used for advanced X/gamma-ray imaging application based on the nuclear resonance fluorescence. In this paper, we will present the optimization of the design.
