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: In an X-ray tube having an X-ray shielding member allowing an electron ray to pass through an electron passing hole toward a target, separately from the cathode-side opening of the electron passing hole, a gas exhaust path allowing communication between the inside and outside of the electron passing hole is provided so that gas molecules generated in the electron passing hole can be easily diffused out of the electron passing hole. The degradation of the cathode caused by accelerated collisions with the cathode, of cations generated by collisions of electrons with gas molecules generated in the electron passing hole by a desorption phenomenon due to electron ray irradiation to the target, is reduced.

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.

Abstract: A compact apparatus can form multi-X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi-electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi-X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

Abstract: A shielding disk for managing x-ray emission form a stationary anode x-ray tube is disclosed. The stationary anode x-ray tube includes an anode housing and a stainless steel can that together form an evacuated enclosure and respectively contain a stationary anode and a cathode assembly. The shielding disk, comprised of tungsten, is interposed between the anode housing and the can, and is formed with a region, such as a hole, formed through a central portion thereof. During tube operation, electrons pass through the shielding disk hole to impact a target surface on the anode and produce x-rays. Those x-rays that do not pass through a window defined in the anode housing to exit the tube but instead emanate toward the can, are intercepted and absorbed by the shielding disk before entering the can. This results in a reduced need for lead shielding disposed about external surfaces of the x-ray tube.
