Abstract: A spark gap including a capacitive energy store is provided. The spark gap is fed via a multiplicity of capacitors arranged in a form of a ring, wherein the capacitors are electrically connected to the anode and the cathode via ring-shaped and conical or funnel-shaped conductors. As a result, sudden changes in impedance can be avoided. At the same time, it is possible to realize as large a cross-sectional area of the conductor as possible within a very small space. Therefore, the spark gap has a switching response with a high rate of rise of the voltage pulse as soon as the spark gaps flash over. This results in an easily predictable switching response of the spark gap. The spark gap can be used, for example, to generate pulses of monochromatic X-ray radiation.

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.

Abstract: An X-ray generating apparatus controls driving of an X-ray tube. The X-ray tube includes an electron source emitting electrons due to application of a voltage, a transmission-type target generating an X-ray due to collision of electrons emitted from the electron source, and a shield member disposed between the electron source and the transmission-type target, the shield member having an opening that electrons emitted from the electron source pass through, and blocking an X-ray that scatters toward the electron source. When generating the X-ray, application of a voltage to the transmission-type target is started, and emission of electrons from the electron source is caused after passage of a predetermined period indicating a time period from starting voltage application until the transmission-type target reaches a predetermined voltage. When stopping X-ray generation, application of the voltage to the transmission-type target is stopped after stopping the emission of electrons from the electron source.
