Abstract :
The load section of a pulsed power generator for X-pinch was designed. It is a work that repeats itself in cycles as follows: making small changes in size and configuration of the electrode system in order to reduce inductance rarr calculating the inductance rarr calculating the load voltage with the measured forward going voltage wave along the pulse transmission line (PTL) incident upon the load rarr calculating the electric field rarr checking if any surface flashover or breakdown in vacuum happens. In the final designed load section, the highest field on the surface of the insulator, a plexiglass diaphragm, is 113 kV/cm and the highest field in vacuum is 298 kV/cm, respectively lower than the surface flashover voltage and the vacuum breakdown voltage in case of an applied pulse voltage of 100 ns of full width at half maximum (FWHIVI) and 500 kV in amplitude.
