Nonlinear Boundary Value Problem of Magnetic Insulation
On the basis of generalization of upper and lower solution method to the singular two point boundary value problems, the existence theorem of solutions for the system, which models a process of magnetic insulation in plasma is proved.
متن کاملMagnetic insulation of a space-charge dominated flow
We report experimental results of magnetic insulation of a space-charge dominated electron flow in a low energy vacuum diode with ferroelectric cathode. Although in the absence of the magnetic field the high current densities are measured well above the estimated space-charge limiting current, the diode is shown to be insulated by a relatively low magnetic field controlled primarily by the anod...
متن کاملDirect current magnetic insulation of an immersed RF antenna
A weak DC magnetic field is applied to an immersed helical resonator antenna in an RF plasma to study the effects of magnetic insulation on potential differences between plasma and antenna within the vacuum chamber. Past research suggests a link between minimizing antenna potential and mitigating self-sputtering effects within the chamber to minimize debris creation. Alteration of particle flux...
متن کاملActive high voltage insulation
This paper presents a new concept for an active high voltage insulation system with dynamic and adaptive features. The governing principle is based on surface charge accumulation on dielectrically covered electrodes in air under atmospheric pressure. This accumulation results in a charge-induced electric field component which steers the field distribution within the system advantageously. At eq...
متن کاملSound insulation issues
This paper gives an overview of three topics related to sound insulation in buildings. The first project included laboratory and field measurements of sound insulation against aircraft noise. As well as various technical papers, the project produced software to help in the design of adequate sound insulation. In a second project, re-analysis of survey results allowed the development of a ration...
