Model of a quasisteady-state electron-beam pinch in rod-pinch diodes

Based on experimental study, a qualitative model was suggested for the electron pinch formation in high-power rod-pinch diodes. In this model, it was assumed that the magnetic field slows the anode plasma expansion during the quasisteady stage of the pinch. The present paper reports on a model of the quasisteady state of the pinch where account is taken of plasma expansion.
