A study of stochastic oscillations generated in the beam-plasma discharge

The paper reports the results from studies into generation of stochastic (chaotic) oscillations due to collective electron beam-plasma interaction. A laboratory high-power generator of stochastic oscillations is created, its main performance characteristics are investigated. The generator is based on a slowing combined plasma-helical system. The experimental results obtained for the dispersion properties of plasma-helical waveguides, threshold and critical currents are in agreement with theory.
