Analysis of magnetron instability for relativistic nonneutral electron flow in cylindrical high-voltage diodes

The magnetron instability in a pulsar’s cylindrical electrosphere

Context. The physics of the pulsar magnetosphere near the neutron star surface remains poorly constrained by observations. Although about 2000 pulsars have been discovered to date, little is known about their emission mechanism, from radio to high-energy X-ray and gamma-rays. Large vacuum gaps probably exist in the magnetosphere, and a non-neutral plasma partially fills the neutron star surroun...

High-Speed, High-Voltage Diodes for High Resolution Monitors

In today’s multimedia orientated society, display devices used as man-to-machine interfaces to facilitate communication have become an indispensable part of daily life in both the public and industrial sectors. CRTs (cathode ray tubes) are the most widely used electric display devices because they provide a low cost, large screen, full-color image with high resolution, high brightness, and quic...

Suppression of resistive hose instability in a relativistic electron–positron flow

This paper presents the effects of electron–positron pair production on the linear growth of the resistive hose instability of a filamentary beam that could lead to snakelike distortion. For both the rectangular radial density profile and the diffuse profile reflecting the Bennett-type equilibrium for a self-collimating flow, the modified eigenvalue equations are derived from a Vlasov–Maxwell e...
