摘要

双轴射线照相水力试验设备(DARHT)第二轴的注入器正在LBNL设计和建造中。注入器由一个单间隙二极管组成，从直径6.5英寸的热离子分配器阴极中提取2 /spl mu/s, 2 kA, 3.2 MeV的电子束。注入器由马克思发电机通过陶瓷柱提供动力。我们还研究了提取4 kA束流的可能性。电子束聚焦系统由位于阴极的皮尔斯静电聚焦电极和位于阳极和感应加速器输入之间的三个螺线管聚焦磁铁组成。

Time dependent beam focusing at the DARHT-II injector diode

The injector for the second axis of the Dual-Axis Radiographic Hydrotest Facility (DARHT) is being designed and constructed at LBNL. The injector consists of a single gap diode extracting 2 /spl mu/s, 2 kA, 3.2 MeV electron beam from a 6.5 inches diameter thermionic dispenser cathode. The injector is powered through a ceramic column by a Marx generator. We also investigated the possibility of extracting a beam current of 4 kA. The focusing system for the electron beam consists of a Pierce electrostatic focusing electrode at the cathode and three solenoidal focusing magnets positioned between the anode and induction accelerator input.
