Magnetized plasma sheaths in an oblique magnetic field were extensively investigated by conventionally assuming Boltzmann relation for electron density. This article presents the study of magnetized sheath without using but considering reflection along lines caused negative potential. A generalized Bohm criterion is analytically derived, and profiles are numerically obtained, which compared with results conventional model. The show that ion Mach number at edge normal to wall has a strong...
The co-excitation of plasma normal modes and a pseudo-mode (burst-ion signal) in beam–plasma system containing stationary ion beam is experimentally investigated double-plasma device. waves are excited by applying ramp voltage to an excitation grid (rather than separation grid) immersed the system. By studying dependence phase velocities signals on characteristics signal ion-beam velocity, four kinds coexisting can be identified, i.e., fast slow modes, ion-acoustic mode, burst-ion signal,...
In a magnetized plasma sheath, strong velocity shear exists owing to the three-dimensional nature of ion velocity. Thus, viscosity should have an important effect on sheath structure, which has not been studied. This article presents study in oblique magnetic field within framework classical cross-field transport. It is shown that inclusion momentum equation results significant reduction thickness. also “generalized Bohm criterion” affected by present model. However, additional boundary...
The even-parity autoionizing resonance series 5p5np′ [3/2]1, [1/2]1, and 5p5nf′5/2]3 of xenon have been investigated, excited from the two metastable states 5p56s [3/2]2 5p56s′ [1/2]0 in photon energy range 28000–42000 cm−1 with experimental bandwidth ̃0.1 cm−1. excitation spectra show typical asymmetric line shapes. New level energies, quantum defects, profile indices widths, lifetimes reduced widths resonances are derived by a Fano-type line-shape analysis. index width shown to be...
