The magnetron instability in a pulsar's cylindrical electrosphere

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...

The diocotron instability in a pulsar “cylindrical” electrosphere

Context. The physics of the pulsar inner magnetosphere remains poorly constrained by observations. Although about 2000 pulsars have been discovered to date, little is known about their emission mechanism. Large vacuum gaps probably exist and a non-neutral plasma made of electrons in some regions and of positrons in some other regions fills space to form an electrosphere. Aims. The purpose of th...

Relativistic stabilisation of the diocotron instability in a pulsar “cylindrical” electrosphere

Context. The physics of the pulsar inner magnetosphere remains poorly constrained by observations. Although about 2000 pulsars have been discovered to date, only little is known about their emission mechanism. Large vacuum gaps exist in the magnetosphere and a non-neutral plasma fills partially the neutron star surroundings to form an electrosphere. Aims. In a previous work, we showed that the ...

2D PIC Simulation of the DC Discharge in Cylindrical Magnetron

PIC method of plasma simulation is widely used in plasma physics research because of its ability to solve wide range of problems in kinetic approach. Regarding to description of PIC method we refer to [Birdsall et al., 1995]. This work is focused on PIC simulations of dc discharge in cylindrical magnetron device. Magnetrons are used in industry e.g. for thin film layer coating and etching. Many...
