Abstract
An electron beam accelerator system includes a high power switching device coupled between the direct current voltage source and the pulse forming network. A pulse control circuit is connected to control the high power switching device to selectively allow a current to flow to the pulse forming network. A voltage difference between a cathode and an anode structure creates an electron beam flowing therebetween. A control grid drive circuit is operatively coupled to the pulse control circuit and the control grid, and is operable to apply a time-varying voltage to the control grid synchronized with the pulse control circuit. The control grid therefore effectively provides a load on the high voltage output of a step-up transformer that prevents overshoot in the transformer output, reducing the risk of dielectric breakdown and failure due to transient high voltages.
