Classification: CPC H  G | IPC H

Claim 0:
1. An x-ray apparatus, comprising:
a vacuum chamber having a window for exit of x-rays, said window having an exterior surface outside of the vacuum in the vacuum chamber;
a cathode within said vacuum chamber;
a solid target anode associated with said window, said target at de having an interior surface within said vacuum Chamber;
a less than 400 kV but more than 80 kW power supply connected between said cathode, and target anode whereby free electrons are accelerated in their flow from said cathode to said target anode within said vacuum chamber;
said interior surface of said target anode comprising an associated x-ray generating layer comprising one or more of an element with an atomic number equal to or greater than 73;
a selectively blocking path beginning at the x-ray generating layer and continuing through the remaining portion of said target anode where said selectively blocking path blocks over 70% of the free electrons reaching said target anode from continuing on to exit through the window, while allowing x-rays leaving the x-ray generating layer to continue along the selectively blocking path to exit through the window; and
a liquid cooling pathway associated with said target anode between said x-ray′ generating layer and the exterior surface of the window for heat transfer from the target anode;
wherein said target anode includes a base plate including stepped surfaces in which risers of said stepped surfaces have sides perpendicular to parallel surfaces of said stepped surfaces.
