New model of electron screening for an ion diode in an external magnetic field

Substantial mechanism of electron mixing resulting from destruction of laminar structure of magnetoisolated electron layer due to instabilities is introduced for consideration. It results in formation of plasma like medium with ne∼B equilibrium state that explains the effects of voltage drop at diode (voltage decay) and of abrupt drop of phase velocity of electromagnetic waves in diode observed in the experiment and in numerical calculations. Comparison of the developed theory with the experiment results in empirical fact of constant rate of electron accumulation in diode gap. 19 refs.; 2 figs
