This report tells about researching of parametric generation in crossed fields. The main attention was preformed to interaction space formed by two coaxial cylinders with an axial magnetic field is a possible parametric generation of electromagnetic oscillations in the absence of the constant anode potential due to inhomogeneous magnetic induction components. Equations of motion were solved numerically...
In order to improve the efficiency and obtain high output power with pure mode, 3-D particle-in-cell simulations are made on a novel coaxial triode vircator. Simulation results show that due to the appearance of the additional cylindrical cathode rod along the centerline, pure TM01 mode can be obtained in the output region. Simulation results also show that high-efficiency and pure TM01 mode output...
The electron sheath and anode double layer are interesting nonlinear structures that usually forms near small anode or a probe biased more positive than plasma potential. The anode fireball and electron sheath is subject to various instabilities and becomes unstable. We devised an experiment with magnetized anode to produce large sized fireball without having to use any biased grid structure1. The...
