An x-ray radiation emitter is provided which comprises an insulating shell, a cap coupled thereto for defining a vacuum chamber, a cathode positioned within the vacuum chamber, and an anode having a distal end disposed proximate the cathode within the vacuum chamber and made of material substantially transparent to x-rays. A layer of target metal disposed on the distal end of the anode is also provided for emitting x-rays when struck by electrons emitted from the cathode upon the application of an electric field between the cathode and the anode.
