Abstract:
1. An x-ray generator comprising: a vacuum tube; an insulator carried within the vacuum tube; an emitter cathode carried within the insulator and emitting electrons and neutral conductive particles, the neutral conductive particles being emitted on a trajectory toward the insulator; at least one shielding electrode carried within the insulator downstream of the emitter cathode; and a target carried within the insulator downstream of the at least one shielding electrode; the emitter cathode and the at least one shielding electrode having a voltage difference therebetween such that an electric field generated in the housing accelerates the electrons toward the target; the at least one shielding electrode being shaped to capture the neutral conductive particles emitted by the emitter cathode that would otherwise strike the insulator; the target emitting x-rays when struck by the electrons.
