寻找新光源，特别是短波长相干光源一直是人们努力追求的目标。将晶体摆动场同速调管技术相结合可望获得短波长相干光源，特别是相干的γ-光源。文章通过晶体摆动场莱塞效应分析，讨论了周期弯晶作为γ-速调管的可能性。在经典力学框架内和小增益近似下，把晶体摆动场中的粒子纵向运动方程化为经典的摆方程，并用摄动法导出了系统的能量增益。结果表明，当弯晶作为放大器模式工作时，要求的束流强度比较高，在级联速调管工作模式下束流强度要求可降低3-4个量级，完全位于当今加速器技术能力范围内。

To find a new light source ,especially short-wave coherent light source has been to strive goal of the people .A combination between crystalline Undulator field with the klystron technology is expected to be short-wave coherent light source ,in particular the coherent γ-light source .In the paper discussed the possibility of a periodic bent crystal as γ-klystron by Lasing effect of the periodic bent crystal .In the framework of classical mechanics and the small gain approximation ,the longitudinal motion equa-tion of the particles in the crystalline Undulator is reduced into classical pendulum equation ,and derived the energy gain of the sys-tem by perturbated method .The results show that when the bent crystal worked in the amplifier mode ,the required beam intensity is more high .If the bent crystal worked in the cascading klystron mode ,the requirements of beam intensity can be reduced by 3-4 or-ders of magnitude ,entirely lie within the capabilities of today′s accelerator technology .
