Electron energy gain in the fundamental mode of an elliptical waveguide in the presence of static helical magnet by microwave radiation

Abstract

To cite this article: A. Abdoli-Arani (2015): Electron energy gain in the fundamental mode of an elliptical waveguide in the presence of static helical magnet by microwave radiation, Waves in Random and Complex Media,The dynamics and energy gain of an electron in the field of a transverse electric wave propagating inside an elliptical waveguide is analytically investigated by considering the existence of a helical magnet in which the field is perpendicular to the axis of the waveguide and rotating as a function of position along the magnet. Besides, by solving the relativistic momentum and energy equations, the deflection angle and the acceleration gradient of the electron in the waveguide are obtained. It is shown that the electron is deflected due to the field components of the transverse electric mode of this microwave, and at the same time, it is accelerated by these fields. Furthermore, the expressions of the acceleration gradient and deflection angle for an electron in the transverse electric mode inside the plasma elliptical waveguide without a static helical magnet are presented, which was injected initially along the propagation direction of the microwave. The results are graphically presented.

Influence of electron–ion collisions in plasma on the electron energy gain using the TE11mode inside an elliptical waveguide

“…However, it is well known that the importance of electron accelerators is dominated by the achievable accelerating gradient. Recently many studies about particle acceleration have been performed [1][2][3][4][5][6][7][8][9][10][11][12]. The energy gain and dynamics of an electron in fields associated with a transverse magnetic (TM) electromagnetic wave propagating inside rectangular [1], cylindrical and elliptical [2,3] waveguides has been studied.…”
