Abstract:
An electron beam accelerator system comprising:a direct current voltage source; a pulse forming network coupled to the direct current voltage source; a high power switching device coupled between the direct current voltage source and the pulse forming network; a pulse control circuit connected to control the high power switching device to selectively allow a current to flow to the pulse forming network; a step-up transformer coupled to the pulse forming network, the step up transformer having a high voltage output; a cathode structure coupled to the high voltage output of the step-up transformer; an anode structure spaced from the cathode structure, the anode structure having a first voltage associated therewith such that a voltage difference exists between the cathode structure and the anode structure, the voltage difference creating an electron beam flowing between the cathode structure and the anode structure; an electron beam output adjacent to the anode structure; a control grid between the cathode structure and the anode structure; and a control grid drive circuit operatively coupled to the pulse control circuit and the control grid, the control grid drive circuit applying a time-varying second voltage to the control grid synchronized with the pulse control circuit.
