在过去的十年中，光注入器已经证明了它们产生非常明亮的电子束的能力，从而成为任何需要强和/或小发射度束的线性加速器的非常有吸引力的注入器。当在给定的规格下设计这样的枪时，有一些简单的规则来选择最适当的参数集是有帮助的。本文简要介绍了射频枪的基本理论和目前可实现的技术参数，从而为设计人员的选择提供了一些指导。简单的标度律和公式的光束动力学和技术参数的建议和现有的光注入器的相应值进行比较。最后，各种复杂的计划，用于提高性能超出了一个简单的方法。
Over the past ten years, photo-injectors have proven their ability to produce very bright electron beams, thus becoming a very attractive injector for any linear accelerator needing intense and/or small emittance beams. When designing such a gun under given specifications, it is helpful to have some simple rules to choose the most adequate set of parameters. This paper gives a quick overview of the basic theory of rf guns and of the presently achievable technical parameters, thus providing some guidelines to help the designer in his choices. Simple scaling laws and formulas for both beam dynamics and technical parameters are proposed and compared to corresponding values for existing photo-injectors. Finally, the various sophisticated schemes used to improve the performances beyond those given by a straightforward approach are reviewed.
