Abstract
An x-ray system for simultaneously or concurrently measuring currents of multiple emitters is provided. The x-ray system includes a high voltage direct current (DC) supply configured to supply tube current to the multiple emitters and plural emitter circuits. Each of these circuits includes each comprising an alternating current (AC) voltage supply, at least one of the multiple emitters operatively coupled to the AC voltage supply and the high voltage DC supply, and a circuit coupling the AC voltage supply and the high voltage DC voltage supply to the at least one of the multiple filaments. At least one of the emitter circuits has a current measurement device between the high voltage DC supply and the emitter.
