“…It is clear that the type of waveguide cross section can play an important role in this goal. Much researches have been done by researchers on the acceleration and dynamics of charged particles in waveguides with rectangular, triangular, circular and elliptical cross sections [15][16][17][18][19][20][21][22][23][24].…”

In this paper,we consider a metallic waveguide with Piet Hein cross section filled by cold unmagnetized plasma. First by introducing a Piet Hein waveguide and considering a suitable approximation,wave equation as two differential equations are presented. Then electromagnetic fields for TM and TE modes in the Piet Hein waveguide filled plasma are analytically obtained and plotted. Using the boundary conditions in the Piet Hein plasma waveguide the dispersion relations for TM and TE modes are analytically derived and plotted. Electron dynamics in the fields associated with a transverse magnetic and electric wave propagating inside the considered Piet Hein plasma waveguide is investigated. The equations of electron motion in the considered Piet Hein plasma waveguide by fourth-order Runge Kutta method for TM and TE modes are solved. The motion path and kinetic energy of electron injected into the purposed configuration for two modes are graphically investigated. In principle, it is shown that the electron can be accelerated in this condition. Therefore, by optimizing the microwave parameters together with the injected energy and waveguide dimensions, a huge amount of energy gain can be obtained if the proposed mechanism can be used in multiple stages.

“…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.…”

The electron acceleration in fields associated with a transverse electric (TE) electromagnetic wave propagating inside a circular [4] and elliptical [5] waveguide has been investigated in the existence of a helical magnet. The acceleration of an injected electron using a microwave source in a cold [6] and warm [7] magnetized plasma-filled cylindrical waveguide with anEH 01 mode has been examined.…”

The influence of electron-ion collisions in plasma on the electron energy gain and total energy of an externally injected electron inside an elliptical waveguide, including collisional plasma using the transverse electric mode, is investigated. It is noted that microwave radiation is used for excitations of the TE 11 even mode in the configuration. The electromagnetic field components of the TE 11  mode in the considered waveguide are obtained and graphically presented. It is seen that the strength of the fields reduces in the collisional plasma. Furthermore, the deflection angle, energy gain of the electron and total energy of the electron due to the mode are obtained. It is illustrated that electron-ion collisions in plasma reduce the energy gain and total energy of electrons injected into the elliptical waveguide.

“…[23] Moreover, electron dynamics in presence of static helical magnet inside circular waveguide has been studied. [24] Recently, it has been shown that the interaction of the microwave with plasma via the TE mode can form density bunches in a cylindrical waveguide, if the standing-wave pattern is realized. These bunches can be tailored by varying the characteristics of microwave and plasma.…”

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.
