Abstract
The apparatus is an x-ray tube which generates collimated x-rays. The x-ray tube anode has an x-ray generating structure which is a single crystal, so that regardless of their locations of origin all the x-ray beams leave the structure at the same limited few angles. With the structure formed as a curve, one set of beams converges at the focal point of the curve, and with the structure flat, the beams illuminate an area with parallel, collimated, x-ray beams.
