The data systems for X-ray free-electron laser (FEL) experiments at the Linac coherent light source (LCLS) are described. These systems are designed to acquire and to reliably transport shot-by-shot data at a peak throughput of 5 GB/s to the offline data storage where experimental data and the relevant metadata are archived and made available for user analysis. The analysis and monitoring implementation (AMI) and Photon Science ANAlysis (psana) software packages are described. Psana is open source and freely available.
本文描述了直线加速器相干光源（LCLS）的X射线自由电子激光（FEL）实验的数据系统。这些系统旨在以5GB/s的峰值吞吐量采集并可靠传输逐次拍摄的数据，将实验数据和相关元数据存档至离线数据存储中，以供用户分析使用。文中还介绍了分析与监测实施（AMI）软件包和光子科学分析（psana）软件包。Psana是开源且免费可用的。
