Abstract
A dual energy X-ray source for use in Homeland Security, Medical, Non-destructive Testing, and other markets includes a power supply, and a single x-ray tube. The X-ray tube includes two cathodes, and a single anode. The electrons from the cathodes travel predominantly along the axis of the x-ray tube, and impact the anode. The grid and/or focus coil direct the electrons so that electrons can pass by the cathode. The cathodes are kept at different potential, such that the tube can rapidly switch energies, and can rapidly switch output flux from each cathode.
