最近，Andriy Kostyuk提出了一种制作晶体波荡器的新方案，并从理论上进行了研究，得出的结论是，一种新型的晶体波荡器不仅可行，而且比以前的方案更好。本文介绍了这种晶体波荡器的第一个实验测量，通过使用Si（1-x）Ge（x）梯度组合物和测量在Mainzer Microtron设施在600和855 MeV的束流能量。我们还提出了理论模型与实验数据进行比较。
A new scheme of making crystalline undulators was recently proposed and investigated theoretically by Andriy Kostyuk, concluding that a new type of crystalline undulator would be not only viable, but better than the previous scheme. This article describes the first experimental measurement of such a crystalline undulator, produced by using Si(1-x)Ge(x)-graded composition and measured at the Mainzer Microtron facility at beam energies of 600 and 855 MeV. We also present theoretical models developed to compare with the experimental data.
