为“闪光二号”加速器研制了新的二极管系统,其电子束能注量比原二极管系统大3倍多。该系统由带滑闪开关的二极管、漂移管、脉冲磁场和真空靶室等部分组成,通过减小阴极直径、增大轴向磁场强度和磁透镜比,调节滑闪开关距离和预脉冲开关气压等技术措施,使二极管具有高能注量电子束输出的稳定工作状态,在Marx发生器充电电压70kV条件下,在距阴极22cm的靶上获得了总能量21.5kJ、束斑直径52mm和能注量1.01kJ/cm2的电子束输出。
Developed a new diode system for the “Flash II” accelerator, which has an electron beam fluence that is more than three times larger than the original diode system. The system consists of a diode with a slide switch, a drift tube, a pulsed magnetic field and a vacuum target chamber. By reducing the cathode diameter, increasing the axial magnetic field strength and the magnetic lens ratio, the system adjusts the slide switch distance and the pre-pulse switch pressure And other technical measures, the diode has a stable working state of high-energy fluence electron beam output. Under the voltage of Marx generator charging voltage of 70 kV, the total energy of 21.5 kJ, the beam spot diameter of 52 mm and the fluence E-beam output of 1.01 kJ / cm2.
