Abstract

Scorpius is a multipulse linear induction accelerator (LIA) under development for flash radiography. The injector uses 42 solenoids to transport the beam through more than 7 m before it enters the main accelerator. Therefore, the beam might be susceptible to corkscrew motion, which is exacerbated by beam energy spread and focusing magnet misalignments. For energy spread and alignment tolerances expected for Scorpius, a magnetic tune designed to transport a matched beam is shown to produce minimal corkscrew motion.

电子束螺旋运动通过天蝎座注入器

天蝎座是一个多脉冲线性感应加速器（LIA）正在开发的闪光射线照相。注入器使用42个螺线管将光束传输超过7米，然后进入主加速器。因此，光束可能容易发生螺旋运动，而光束能量的扩散和聚焦磁体的错位会加剧这种运动。对于天蝎座预期的能量扩散和对准公差，设计用于传输匹配光束的磁调谐显示产生最小的螺旋运动。
