摘要

本文对长笛的束压缩进行了分析研究，并将结果与模拟结果进行了比较。FLUTE是一种基于直线加速器的电子加速器，设计能量约为40 MeV，目前正在卡尔斯鲁厄理工学院建造。长笛的目标之一是产生长度在飞秒范围内的电子束。在第一阶段，这将使用磁束压缩机来完成。这个压缩机构成了本研究的主题。本文分为两部分。第一部分讨论了束压缩器的纯几何研究，其中忽略了空间电荷效应和相干同步辐射束的反作用。第二部分是空间电荷效应的处理。结果是，两部分的分析结果与模拟结果相当吻合。本文将为今后对长笛串压缩机和串压缩机的分析研究奠定基础。

Analytical bunch compression studies for a linac-based electron accelerator

The current paper deals with analytical bunch compression studies for FLUTE whose results are compared to simulations. FLUTE is a linac-based electron accelerator with a design energy of approximately 40 MeV currently being constructed at the Karlsruhe Institute of Technology. One of the goals of FLUTE is to generate electron bunches with their length lying in the femtosecond regime. In the first phase this will be accomplished using a magnetic bunch compressor. This compressor forms the subject of the studies presented. The paper is divided into two parts. The first part deals with pure geometric investigations of the bunch compressor where space charge effects and the backreaction of bunches with coherent synchrotron radiation are neglected. The second part is dedicated to the treatment of space charge effects. The upshot is that the analytical results in the two parts agree quite well with what is obtained from simulations. This paper shall form the basis for future analytical studies of the FLUTE bunch compressor and of bunch compression, in general.

期刊介绍： Physical Review Special Topics - Accelerators and Beams (PRST-AB), is a peer reviewed, purely electronic journal, distributed without charge to readers and funded by contributions from national laboratories. It covers the full range of accelerator science and technology: subsystem and component technologies, beam dynamics; accelerator applications; and design, operation, and improvement of accelerators used in science and industry. This includes accelerators for high-energy and nuclear physics, synchrotron radiation production, spallation neutron sources, medical therapy, and intense beam applications.
