摘　　要：主要介绍 CRRFA-30 L波段射频加速器结构和性能 ,论述了热阴极射频腔注入器、束流加速系统、微波功率源和控制等结构中主要技术及其研究进展 ,给出了加速器输出束流参数测量与测量结果分析 。A CRRFA-30 L band linac is described. An electron beam of 2 MeV is obtained from a thermionic cathode 1+1/2 RF-Gun, followed by an α - magnet with the beam current of 300 mA. Then the beam is accelerated through three linac tanks. The first linac tank with 5 cells is driven by a KL-28 klystron RF system which can produce up to 3.5 MW of peak output power, and accelerate the electron to 8 MeV. The second and third linac tanks consist of 11 cells separately, each tank is powered by a KL-54 klystron RF system which can produce up to 10 MW of peak output power, and accelerate the electron to 17.6 MeV and 28 MeV, respectively. The linac outputs electron beams of 290 mA with energy spread of &le1.4%, emittance of 9π mm-mrad, and brightness of 1.5×1010A/(m&middotrad)2. The accelerating structure, performances and experimental results are described. The linac works stably, and will be used in the free electron laser (FEL), the study of electron energy recovery and basic research of flash photograph.
