ABSTRACT:
A pixel array arrangement is provided for a soft x-ray source. The arrangement includes: a window-frame structure having a plurality of channels passing therethrough, where each channel forms a pixel for the x-ray source; a cathode disposed on one side of each channel in the window-frame structure and operable to emit electrons into the channel; and an anode disposed in each cavity on an opposing side of the channel from the cathode and operable to emit x-ray radiation when electrons from the cathode impinge thereon, where the anode is configured to emit x-ray radiation at a diffused angle such that the x-ray radiation from a given pixel overlaps with x-ray radiation from adjacent pixels.
