Title: Electron dynamics and acceleration study in a magnetized plasma-filled cylindrical waveguide

Abstract

In this article, EH{sub 01} field components are evaluated in a cylindrical waveguide filled with plasma in the presence of external static magnetic field applied along the direction of the mode propagation. The electron acceleration inside the plasma-filled cylindrical waveguide is investigated numerically for a single-electron model. It is found that the electron acceleration is very sensitive to the initial phase of mode-field components, external static magnetic field, plasma density, point of injection of the electron, and microwave power density. The maximum amplitude of the EH{sub 01} mode's field components is approximately 100 times greater than the vacuum-waveguide case for operating microwave frequency f=7.64 GHz, plasma density n{sub 0}=1.08x10{sup 17} m{sup -3}, initial phase angle {phi}{sub 0}=60 deg., and microwave power {approx}14 MW in a cylindrical waveguide with a radius of 2.1 cm. An electron with 100 keV gets 27 MeV energy gain in 2.5 cm along the waveguide length in the presence of external power {approx}14 MW with a microwave frequency of 7.64 GHz. The electron trajectory is also analyzed under the effects of magnetic field when the electron is injected in the waveguide at r=R/2.
