直线加速器相干光源使用光栅单色仪系统为软 X 射线范围添加了自播种功能。我们报告了软 X 射线自播种的演示，测得的分辨率为 2000-5000，波长稳定性为 10(-4)，并且在 500-1000 eV 的光子能量范围内峰值亮度增加了 2-5 倍。通过避免在实验站使用单色仪，自播种光束可以为用户提供高达 50 倍的亮度。
The Linac Coherent Light Source has added a self-seeding capability to the soft x-ray range using a grating monochromator system. We report the demonstration of soft x-ray self-seeding with a measured resolving power of 2000-5000, wavelength stability of 10(-4), and an increase in peak brightness by a factor of 2-5 across the photon energy range of 500-1000 eV. By avoiding the need for a monochromator at the experimental station, the self-seeded beam can deliver as much as 50-fold higher brightness to users.
