Abstract: An x-ray source assembly includes an anode stack including a source spot upon which electrons impinge with power being supplied to the assembly, and a control system to facilitate maintaining intensity of output x-rays from the x-ray source assembly during operation. The control system is configured to actively control temperature of the anode stack relative to a setpoint or defined setpoint range. The control system heats the anode stack in a heating mode, when an anode stack temperature is below the setpoint or defined setpoint range, and switches to a cooling mode to cool the anode stack when the anode stack temperature rises above the setpoint or defined setpoint range.

Abstract: A shielded, low-noise, high-voltage power supply having a plurality of voltage multipliers, each having a toroidal transformer, and collectively producing a high DC output voltage from an AC voltage. A main conductor carries the AC voltage, and is positioned proximate each toroidal transformer of the plurality of voltage multipliers. A conductive shell is conductively connected to the main conductor, and substantially encloses the plurality of voltage multipliers and the main conductor, the conductive shell providing a return path for the AC voltage in the main conductor and providing EMI shielding of the voltage multipliers and the main conductor. Other features are provided, including an intermediate transformer for conditioning/isolating the AC voltages.
