The Linac Coherent Light Source (LCLS) is an x-ray free-electron laser project presently in a commissioning phase at the SLAC National Accelerator Laboratory. We report here on very low-emittance measurements made at low bunch charge, and a few femtosecond bunch length produced by the LCLS bunch compressors. Start-to-end simulations associated with these beam parameters show the possibilities of generating hundreds of GW at 1.5 A x-ray wavelength and nearly a single longitudinally coherent spike at 1.5 nm with 2-fs duration.
直线加速器相干光源（LCLS）是一个正在斯坦福直线加速器中心国家加速器实验室调试阶段的X射线自由电子激光项目。我们在此报告在低束流电荷下进行的极低发射度测量，以及LCLS束团压缩器产生的几飞秒束团长度。与这些束流参数相关的从头到尾的模拟显示了在1.5埃X射线波长下产生数百吉瓦以及在1.5纳米波长下产生持续时间为2飞秒的几乎单个纵向相干尖峰的可能性。
