Abstract
An x-ray generator includes a voltage source and a voltage divider network coupled thereto, a housing, and an insulator carried within the housing. An emitter cathode is carried within the housing and emits electrons and undesirable conductive particles. In addition, there is a shielding electrode carried within the housing downstream of the emitter cathode and coupled to the voltage divider network. A target is carried within the housing downstream of the at least one shielding electrode. The voltage divider is configured so that the emitter cathode and the shielding electrode have a voltage difference therebetween such that an electric field generated in the housing accelerates electrons emitted by the emitter cathode to toward the target. The shielding electrode is shaped to capture the undesirable conductive particles emitted by the emitter cathode that would otherwise strike the insulator.
