Abstract:
1. A x-ray generating apparatus comprising: a plurality of electron emission sources aligned along a certain direction; a plurality of targets configured to receive an electron beam emitted from each of the plurality of electron emission sources and to generate x-rays, each one of the plurality of targets including a target film and a transmissive substrate, the target film and the transmissive substrate arranged in this order with respect to a corresponding electron emission source such that a x-ray generated from the target film transmits through the transmissive substrate; and a shielding member having a plurality of apertures, each aperture configured to hold a corresponding one of the targets having the target film and the transmissive substrate, wherein each aperture is configured to shield a part of the x-ray emitted from a corresponding target, and wherein any adjacent two of the plurality of transmissive substrates are connected via the shielding member such that any adjacent two of the plurality of targets are connected via the shielding member and wherein the shielding member acts as a thermal transfer path.
