我们介绍了在LCLS的双模块RadiaBeam/SLAC解调系统的调试结果。这是首次在高能(4.4，13.3 GeV)、短脉冲(<；200飞秒)下安装和测量波纹去毛线器，同时观察其对运行自由电子激光器的影响。横向和纵向尾波场都允许更灵活的电子束定制。我们验证了，对于给定间隙的单个模块，轴上的纵向尾迹和靠近轴线的偶极子的强度与理论值很好地吻合。利用直接纵向相空间映射和X射线自由电子激光光谱测量，我们展示了能量啁啾控制能力。
We present results on the commissioning of the twomodule RadiaBeam / SLAC dechirper system at LCLS. This is the first installation and measurement of a corrugated dechirper at high energy (4.4 13.3 GeV), short pulses (< 200 fs) and while observing its effect on an operational FEL. Both the transverse and longitudinal wakefields allow more flexible electron beam tailoring. We verify that, for a single module at a given gap, the strength of the longitudinal wake on axis and the dipole near the axis agree well with the theoretical values. Using direct longitudinal phase space mapping and X-ray FEL spectrum measurements we demonstrate the energy chirp control capabilities.
