报道了SACLA软X射线自由电子激光光束线的现状。描述了SPRING-8紧凑型自由电子激光器(SACLA)的软X射线自由电子激光器(FEL)光束线的设计和性能。作为SACLA的原型机，SPRING-8紧凑型SASE源测试加速器被重新安置到SACLA波荡器大厅，专门用于软X射线自由电子激光光束线。由于加速器独立于驱动两条硬X射线光束线的SACLA主直线加速器运行，因此可以同时产生软X射线自由电子激光和硬X射线自由电子激光。自由电子激光脉冲能量达到110MeV，波长为12.4 nm(即光子能量为100 eV)，电子束能量为780 MeV。
The status of a soft X-ray free-electron laser beamline at SACLA is reported. The design and performance of a soft X-ray free-electron laser (FEL) beamline of the SPring-8 Compact free-electron LAser (SACLA) are described. The SPring-8 Compact SASE Source test accelerator, a prototype machine of SACLA, was relocated to the SACLA undulator hall for dedicated use for the soft X-ray FEL beamline. Since the accelerator is operated independently of the SACLA main linac that drives the two hard X-ray beamlines, it is possible to produce both soft and hard X-ray FEL simultaneously. The FEL pulse energy reached 110 µJ at a wavelength of 12.4 nm (i.e. photon energy of 100 eV) with an electron beam energy of 780 MeV.
