欧洲XFEL正在投资开发超导波荡器(SCU),用于未来升级其光束线。由NbTi制成的SCU在2K下工作,具有15 mm的周期长度和5 mm的真空间隙,允许覆盖54 keV和100 keV之间的范围。波荡器参数K沿着波荡器的分布中的机械误差的影响对于较低光子能量处的工作点更相关,这是使用波荡器中的较高磁场获得的。在本文中,我们研究的K参数的误差分布的影响,在50 keV的光子能量获得的工作点注入电子束与16.5 GeV的能量从XFEL直线加速器在一个波荡器线组成的SCU与1.6 T的峰值磁场。
European XFEL is investing in the development of superconducting undulators (SCUs) for future upgrade of its beamlines. SCUs made of NbTi, working at 2 K, with a period length of 15 mm and a vacuum gap of 5 mm allow covering a range between 54 keV and 100 keV. The effect of mechanical errors in the distribution of the undulator parameter K along the undulators is more relevant for working points at lower photon energy, which are obtained using a higher magnetic field in the undulator. In this article we investigate the effect of error distribution in the K-parameter for a working point at 50 keV photon energy obtained injecting an electron beam with 16.5 GeV energy from the XFEL linear accelerator in a undulator line composed by SCUs with 1.6 T peak magnetic field.
