Волновые эффекты в коаксиальном тракте при субнаносекундном переключении высоковольтного диода в режиме задержанного ударно-ионизационного пробоя

Theoretical analysis of wave processes in the coaxial line during subnanosecond switching of high-voltage pulse sharpening diode is presented. The relations between amplitudes of the incident, reflected and transmitted waves and experimentally measured voltages as well as between these voltages and triggering generator pulse are established. The effect of the diode voltage doubling before switching is calculated. On the basis of the obtained relations and experimental data the time dependence of the sharpening diode reflection coefficient is determined and the wave dynamics in the coaxial line during avalanche switching are reconstructed.
