伯克利实验室已经提出建立一个基于循环直线加速器的X射线源，用于超快动态研究[J. Corlett，et.例如，“一个基于直线加速器的超快X射线科学再循环装置”，Proc.2003部分。加速老化确认，波特兰，2003年]。该机器需要具有小垂直发射度和大x/y发射度比的扁平电子束，以压缩软X射线脉冲和硬X射线脉冲的自发波荡器发射，以及低发射度的圆形电子束，用于相干发射软X射线通过基于级联谐波产生的自由电子激光过程[W. Fawley，et.例如，“Simulation Studies of an XUV/Soft X-Ray Harmonic-Cascade FEL for the Proposed LBNL Recirculating Linac;，Proc. 2003 Part.加速老化确认，波特兰，2003年]。我们提出了一种由两个高梯度高重复率光阴极电子枪组成的注入器系统[J.斯台普斯等]。例如，“The LBNL Femtosource 10 kHz Photoinjector”，Proc.2003 Part.加速老化确认，波特兰，2003年。] (one对于每种应用）、/splsim/120 MeV超导线性加速器、用于纵向相空间线性化的第三谐波腔以及聚束压缩器。我们目前的设计细节和使用几个计算机代码的粒子跟踪研究的结果。
Berkeley Lab has proposed to build a recirculating linac based X-ray source for ultra-fast dynamic studies [J. Corlett, et. al., "A Recirculating Linac-Based Facility for Ultrafast X-ray Science", Proc. 2003 Part. Accel. Conf., Portland, 2003.]. This machine requires a flat electron beam with a small vertical emittance and large x/y emittance ratio to allow for compression of spontaneous undulator emission of soft and hard x-ray pulses, and a low-emittance, round electron beam for coherent emission of soft x-rays via the FEL process based on cascaded harmonic generation [W. Fawley, et. al., "Simulation Studies of an XUV/Soft X-Ray Harmonic-Cascade FEL for the Proposed LBNL Recirculating Linac;, Proc. 2003 Part. Accel. Conf., Portland, 2003.]. We propose an injector system consisting of two high gradient high repetition rate photocathode guns [J. Staples, et. al., "The LBNL Femtosource 10 kHz Photoinjector', Proc. 2003 Part. Accel. Conf., Portland, 2003.] (one for each application), a /spl sim/120 MeV superconducting linear accelerator, a 3rd harmonic cavity for linearization of the longitudinal phase space, and a bunch compressor. We present details of the design and the results of particle tracking studies using several computer codes.
