Some embodiments include a system, comprising: a high voltage enclosure; a cathode disposed in the high voltage enclosure; an anode disposed in the high voltage enclosure; a plurality of grids disposed in the high voltage enclosure between the cathode and the anode; a voltage source configured to generate a common grid voltage; and a voltage divider disposed in the high voltage enclosure, configured to generate a plurality of grid voltages based on the common grid voltage, and configured to apply at least two of the grid voltages to the grids.

Multi-grid electron gun with single grid supply

An x-ray imaging system is disclosed, where one example of such a system includes a frame or other structure to which a modular cooling unit of the x-ray imaging system is attached. The modular cooling unit includes a radiator, configured for fluid communication with an x-ray tube housing, as well as one or more fans configured to cause a flow of air to pass through the radiator. In this example, the x-ray imaging system further includes a detector array arranged to receive x-rays generated by an x-ray tube insert disposed within the x-ray tube housing. In operation, the air flow caused by the fans of the modular cooling unit removes heat from coolant flowing out of the x-ray tube housing and through the radiator.
