We developed a vacuum-compatible pulse selector for a free-electron laser. A rotating cylinder with eight apertures in a vacuum is driven by a closed-loop stepping motor system through a magnetically coupled rotary feedthrough. A field programmable gate array is used to synchronize the cylinder rotation with a trigger signal of the accelerator at a maximum repetition rate of 60 Hz. We achieved to select specific pulses from a continuous pulse train of the SPring-8 Compact SASE Source.
我们为自由电子激光开发了一种真空兼容脉冲选择器。一个在真空中带有八个孔的旋转圆柱体由闭环步进电机系统通过磁耦合旋转馈通驱动。现场可编程门阵列用于使圆柱体旋转与加速器的触发信号同步，最大重复频率为60Hz。我们成功地从SPring-8紧凑型自放大自发辐射源的连续脉冲序列中选择特定脉冲。
