束腔互作用

Beam cavity interaction

A. Gamp

摘要:

我们首先从基本量的角度描述射频发生器-腔-束耦合系统。考虑到束流加载和腔失谐量,导出了发生器和束流所见的腔阻抗表达式。随后,通过腔失谐,射频反馈和前馈的梁加载补偿的方法进行了描述。对于超导腔的特殊情况,给出了数字射频相位和幅度控制的例子。最后,讨论了一种专用的阻尼同步振荡的相位环。

英文摘要:

We begin by giving a description of the rf generator-cavity-beam coupled system in terms of basic quantities. Taking beam loading and cavity detuning into account, expressions for the cavity impedance as seen by the generator and as seen by the beam are derived. Subsequently methods of beam-loading compensation by cavity detuning, rf feedback, and feed-forward are described. Examples of digital rf phase and amplitude control for the special case of superconducting cavities are also given. Finally, a dedicated phase loop for damping synchrotron oscillations is discussed.
