Matching a Blumlein Modulator to a Non-Linear Load

Abstract

The system studied consisted of a Blumlein modulator driving a sharpening spark gap in series with a carbon felt cathode electron gun. The spark gap is preset to fire at the E-gun operating voltage. A computer simulation of the system was made and was consistent wi th the system behavior. In order to eliminate large voltage excursions on the E-gun and to achieve a flat top it was necessary to place a capacitor across the spark gap/E-gun combination to provide an initial low impedance load and damp the oscillations. In the 10 microsecond case, in addition to the damping capacitor, it was necessary to taper a few sections of each line of the Blumlein network to compensate for the larger impedance change in the E-gun.
