摘要
上海自由电子激光(SFEL)工程是国家重大科技基础设施建设项目,束流稳定性的好坏是影响SFEL性能的关键指标,而地基振动是影响束流稳定性的重要因素之一。本文对SFEL工程的地基振动进行了长达450m、24h连续测试;对不同位置、不同时刻、不同频段、不同方向的结果进行了详细地分析,并与国外光源的地基振动结果进行了比较,为SFEL工程的建设准备了比较详细的地基振动资料。
Beam stability is one of the most important requirements for Shanghai free electron laser （SFEL） project, which will be a huge scientific platform for science research and technology development in China. However, ground vibration is one of the main factors affecting the beam stability. In this paper, we report the results of ground vibration measurements on 24-hour basis at points in a line of 450 m. Vibrations at different positions, hours, frequency bands and directions were analyzed, and amplitudes of the vibrations were compared with similar projects in the world.
