Abstract

We present the results of studies aimed at creation of accelerating structures for a photoinjector accelerator that is currently under construction at the IAP RAS. Based on the general theory of coupled oscillators, a simple method for diagnosing the resonant properties of two-cell accelerating structures is given. Electrodynamic measurements of the manufactured photogun at a low power level confirm the ability to achieve the required acceleration gradient, although they show quite a notable difference between its resonant properties and the design. These measurements are in good agreement with analytical estimates and numerical simulations. The project of an additional accelerating structure designed to further accelerate the photoinjector electron bunches up to the energy providing their efficient injection into a wakefield plasma accelerator is also presented.

设计和测试光枪谐振器和用于 IAP RAS 光注射器的带行波的双周期加速结构

我们介绍了旨在为目前正在 IAP RAS 建造的光注射加速器创建加速结构的研究成果。根据耦合振荡器的一般理论，我们给出了一种诊断双室加速结构共振特性的简单方法。在低功率水平下对制造的光枪进行的电动力学测量证实，它有能力达到所需的加速梯度，尽管测量结果表明其谐振特性与设计之间存在相当大的差异。这些测量结果与分析估计和数值模拟结果非常吻合。此外，还介绍了一个附加加速结构的项目，该结构旨在进一步加速光电喷射器的电子束，使其达到能将电子束有效注入唤醒场等离子加速器的能量。
