摘要:

除了追求窄带宽的X射线脉冲外,大带宽的自由电子激光脉冲也是满足广泛科学用户实验的迫切需求。本文讨论了利用偏转腔和/或波纹结构实现的横向倾斜束流,利用平面波荡器的自然梯度产生大带宽X射线自由电子激光的可能性。模拟结果证实了理论预测的正确性,X射线自由电子激光带宽随参数的优化提高了一个数量级。

英文摘要:

Besides the target to pursue the narrow bandwidth X-ray pulses, the large bandwidth free-electron laser pulses are also strongly demanded to satisfy a wide range of scientific user experiments. In this paper, using the transversely tilt beam enabled by deflecting cavity and/or corrugated structure, the potential of large bandwidth X-ray free-electron lasers generation with the natural gradient of the planar undulator are discussed. Simulations confirm the theoretical prediction, and X-ray free-electron laser bandwidth indicates an increase of one order of magnitude with the optimized parameters.
