We report microwave emission measurements from an inverted relativistic magnetron comprising an outer cylindrical field emission cathode and an inner coaxial anode with embedded vane resonators. The magnetron operates in the w mode at a frequency of %3.6GHz, and voltages of 1-2MV. The RF power is %500MW.

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...

A new microwave tube design, suitable for application in microwave ovens, is described. It is a development of the basic planar magnetron in which the cathode and anode are two annuli and the magnetic field is radial. Potential advantages over existing designs are: higher power density, higher efficiency, easier tuning, the probability of reduced harmonics, and lower manufacturing costs. The wo...

In this contribution we report the results obtained using a newly developed self-consistent fully 3D Particle-In-Cell code for modelling of plasma-solid interaction. The model presented here involves a hollow cylindrical chamber opened to the plasma, with an external magnetic field limiting access of charged particles to the cylindrical wall. This model layout might provide more insight into pr...

An Object Oriented Particle-in-Cell model of a plasma glow discharge in a cylindrical magnetron cleaning device has been developed to provide guidance in developing a novel in situ surface conditioning technique. The model tracks the trajectories of particles by solving the equations of motion and the electrostatic field equations. Simulation results are compared to experimental measurements ob...

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...
