摘要: 光阴极超导加速器实验系统由四倍频Nd:YAG锁模激光器、Cs2Te光阴极、2+1/2微波电子枪、L波段3.5MW脉冲微波源,1.3GHz单腔超导铌腔,500W连续微波源,超导腔束管耦合器,4.2K低温恒温容器,液氦制冷系统,同步控制系统,束流参数诊断,真空系统等构成。2001年6月在中物院进行了光阴极超导加速器原理性实验,测得超导加速段能量增益0.58MeV,微脉冲束流强度0.1A,取得了预期的实验结果。Abstract: Photo-cathode superconducting accelerator experiment system include Nd:YAG Mode-locked laser, Cs2Te cathode, 2+1/2 RF gun, L band 3.5MW Microwave source, 1.3GHz superconducting cavity, 500W continue microwave source, coaxial input coupler, 4.2K cryostat, helium liquefied system, control system, beam diagnostic, and vacuum system. In June 2001, the experiment of this system have been done in CAEP. The electron beam energy gained in superconducting cavity is 0.58MeV, micro-pulse current is 0.1A.
