Elliptical plasma-filled waveguide as a new standard short-period undulator

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