energetic electrons that are driven by a strong electric field and have kinetic energies of several MeV. Electron beams with more than 300 keV kinetic energy are categorized as high energy beam and those with kinetic energy below 300 keV are categorized as low energy beam (Yousefi et al., ...
In this system, the electron density n(r) is uniform over space, and thus the electron number is infinite. The negative charge of the electrons is neutralized by a rigid uniform positive background. The noninteracting kinetic energy and exchange energy per electron for a spin-unpolarized ...

mainly the formation and decay of the current filaments and sheets. We consider a collisionless expansion of an anisotropic plasma cloud with hot electrons into a background plasma and take into account an external magnetic field in different geometries entailing (i) a hot-electron spot of a circ...

Self-charging power systems collecting energy harvesting technology and batteries are attracting extensive attention. To solve the disadvantages of the tra
(BSRF). The electron storage ring at SSRF operated at 3.5 GeV and with an average current of 300 mA, and the electron storage ring operated at 2.5 GeV and with an average current of 250 mA at BSRF, respectively. In both beamlines, a pair of Si(111) monochromator crystals were employed...
To calculate the maximal harmonic order, we do not require that the initial electron velocity be zero. We require that the electron trajectory is extremal with respect to the kinetic energy, i.e., ∂ E k ( t , t ′ ) / ∂ t ′ = 0 and ∂ E k ( t , t ′ ) / ∂ t...
Electron microscopy is widely used to directly observe the shape and size of NPs, while dynamic light scattering (DLS) can estimate their hydrodynamic diameter. Also, the features regarding the crystalline structure of the particles are analyzed by X-ray diffraction. Fourier-transform infrared ...
Question: An electron with a speed of 5.51×108 cm/s in the positive direction of an x axis enters an electric field of magnitude 2.87×103 N/C, traveling along a field line in the direction that retards its motion. (a) How far will t...
