Abstract
We propose and test experimentally the design of a planar micro-undulator, which allows ensuring a simple profile of the undulator parameter with a value of about unity at a period of 1 mm, as well as the possibility to operate in a regime with a repetition frequency of tens of hertz. Along with small-size sources of high-density beams of accelerated electrons, such as the photo-injection accelerator or the plasma wakefield accelerator, this micro-undulator can be used to make small-size sources of the terahertz and X-ray radiation. It is shown that the Joule heating inhibits the further decrease in the period value. Analytical estimates of the undulator parameter agree well with both the results of numerical simulations and the results of experimental tests.
我们提出并通过实验测试了一种平面微型激励器的设计，这种激励器可以确保在 1 毫米周期内，激励器参数的轮廓非常简单，其值大约为一，并且可以在重复频率为几十赫兹的情况下工作。除了小型高密度加速电子束源（如光射加速器或等离子体唤醒场加速器）之外，这种微型衰减器还可用于制造小型太赫兹和 X 射线辐射源。研究表明，焦耳加热抑制了周期值的进一步下降。对衰减器参数的分析估计与数值模拟结果和实验测试结果都非常吻合。
