Abstract

Two-beam acceleration is a powerful method to generate high accelerating fields by utilizing short radiofrequency pulses. The Argonne Wakefield Accelerator facility is applying a two-beam acceleration approach to an X-band radiofrequency gun. This gun has experimentally demonstrated an electric field on the photocathode of

\sim 400

MV/m. The next phase of this experiment will involve adding a short X-band linac to boost the beam energy up to 10 MeV. This paper summarizes the optimization of the linac and beam dynamics simulations in the integrated system over a wide range of operating parameters and demonstrates that the available setup will support the generation of bright or ultrashort beams with possible applications to compact light sources including inverse Compton scattering.

一个集成的尾流场驱动的高梯度x波段光注入器，用于紧凑型光源应用

双束加速是一种利用短射频脉冲产生高加速场的有效方法。阿贡韦克菲尔德加速器设施正在将双光束加速方法应用于x波段射频枪。该枪在实验上证明了光电阴极上的电场为~ 400 MV/m。该实验的下一阶段将包括增加一个短x波段直线加速器，以将光束能量提高到10兆电子伏。本文总结了在广泛的工作参数范围内对集成系统中的直线和光束动力学模拟的优化，并证明了可用的设置将支持产生明亮或超短光束，并可能应用于包括逆康普顿散射在内的紧凑光源。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
