摘要
“神龙一号”注入器是直线感应加速器的束流源 ,它采用了感应叠加的高压加载方式 ,包括脉冲功率系统、感应腔、阴阳极杆、绝缘支撑、二极管和束流传输系统等子系统 .在研制中采用了径向绝缘支撑、对中支撑调节系统、类Pierce阴极等先进技术 ,以及二极管线圈内置和外径为 80 0mm的铁氧体大环等创新 .参数测试显示 ,3.5MeV注入器达到了世界先进水平 .
MeV injector is the electron beam source of Dragon-I induction linac. Electron beam is extracted by the magnetic field from diode powered by an induction voltage adder, which is composed of pulsed power system, induction cavities, cathode/anode stem and radial insulator. Innovation is adopted in the development such as Pierce-like cathode, 800mm OD ferrite torroid and solenoids placed inside cathode/anode. Measurement shows that this injector is of high performance with output beam of 2.8kA , 3.7MeV, and normalized emittance of 1040π·mm·mrad, energy spread of 2.1%.
