摘要: 光学速调管自发辐射的结果是鉴定其性能的指标之一。根据合肥同步辐射环上采用的光学速调管和实测的磁场数据，计算了单能电子束和具有不同能散度电子束的自发辐射谱及相应的小信号增益谱，结果表明光学速调管的性能是好的。Abstract: The spontaneous emission is one important performance of an optical klystron (OK). Using the magnetic field data which were measured from OK on the storage ring of NSRL, spontaneo us emission and small signal gain of the electron beam with different energy spread in OK has been computed in this paper. The results illustrates that OK in storage ring of NSRL can satisfy the experimental requirement.
