Undulators as the sources of high-brilliance synchrotron radiation are of widespread interest in new generations of light sources and free-electron lasers. Microwave propagation in a plasma-filled elliptical waveguide can be studied as a standard short-period undulator. This structure as a lucrative insertion device can be installed in the storage ring of third- and fourth-generation light sources to produce high-energy and high-brilliance synchrotron radiation. In this article, the propagation of the transverse electric modes in a plasma-filled waveguide with an elliptical cross-section is investigated, and the field components, the cut-off frequencies and the electron beam trajectory are calculated. With due consideration of the electron beam dynamics and in order to achieve a standard short-period undulator, parameters such as the dimensions of the waveguide elliptical cross-section, the microwave frequency and the plasma density are calculated.

椭圆形等离子体填充波导作为新的标准短周期波荡器

作为高亮度同步辐射源的波荡器在新一代光源和自由电子激光器中受到广泛关注。微波在充满等离子体的椭圆波导中的传播可以作为标准的短周期波荡器进行研究。这种结构作为一种有利可图的插入装置，可以安装在第三代和第四代光源的存储环中，以产生高能量、高亮度的同步辐射。在本文中，研究了横向电模式在具有椭圆截面的等离子体填充波导中的传播，并计算了场分量、截止频率和电子束轨迹。适当考虑电子束动力学并为了实现标准的短周期波荡器，
