摘要

用于闪光射线照相的线性感应加速器（LIAs）中的光束分裂（BBU）存在问题，因为高频光束运动会模糊源点，从而降低分辨率。BBU可以被任何频率与电池模式共振一致的射频源激发。放大直接取决于电池设计的细节，并在操作中被用于电子束传输的螺线管磁场抑制。以前的工作研究了射频、波束头上升时间或螺旋运动激励的BBU。在本文中，我们将这些研究扩展到噪声激励，发现它可以增长到更低的振幅。

Further Beam Breakup Simulations for the Scorpius Linear Induction Accelerator

Beam breakup (BBU) in linear induction accelerators (LIAs) used for flash radiography is problematic because the high-frequency beam motion can blur the source spot, thereby degrading resolution. BBU can be excited by any source of RF with frequencies coinciding with cell mode resonances. Amplification depends directly on details of cell design and is suppressed in operation by the solenoidal magnetic field used for transport of the electron beam. Previous work has studied BBU excited by RF, beam head rise time, or corkscrew motion. In this article, we extend these investigations to excitation by noise, finding that to grow to much lower amplitude.
