摘要: X/γ探测器在航天等国家战略需求领域具有非常广泛和重要的应用。 然而， X/γ探测器要在其有效能区进行精确的标定后才能发挥作用。 目前我国缺乏subMeV～MeV能量连续可调、 单色性好的γ源， 而用于航天的X/γ探测器无法完成精确定标， 从而使航天探测的发展出现瓶颈问题。 提出了升级原有的激光康普顿散射(LCS)原理性实验装置的方案， 建立了一个通过改变激光入射角来连续调节散射光子能量、 准单色、 极化、 subMeV～MeV LCS光源(SINAP-III)， 从而开拓LCS光源在我国航天领域（如用于航天的X/γ探测器能量定标和抗辐射加固评估研究）的崭新应用前景， 并为将来建设一个基础和应用研究相结合的多功能的γ源实验平台打下基础。 The X/γ detectors in the field of national stratagem， such as astronautical technology， have very broad and important application. These detectors， however， will play their role properly only after accurate calibrations in effective energy region. For the shortage of continuously adjustable and quasimonochromatic γ source in China， it is impossible for the detector employed in aerospace to achieve an accurate calibration so that development of such detector has encountered a big obstacle (or a bottleneck). Therefore， we propose to upgrade the original LCS device to an adjustable photon energy by changing incident angle of laser beam， monochromatic， and polarized subMeV~MeV LCS γ source(SIMAPIII) ， in order to explore the new applications of LCS γ source in aerospace as well as to establish a platform for a multifunctional of γ source.
