摘要： X-ray tube systems and methods are described herein. A system for creating a vacuum environment in an X-ray tube assembly includes a vacuum tube having a first end and a second end, the first end of the vacuum tube welded to a support plate of the X-ray tube assembly, and the second end of the vacuum tube is pinched off or cold pressed to seal the vacuum environment within the X-ray tube insert of the X-ray tube assembly. A method of creating a vacuum within an X-ray tube assembly includes welding a first end of a vacuum tube to a support plate of the X-ray tube assembly, coupling a second end of the vacuum tube to a vacuum pump, using a vacuum pump to create a vacuum environment in the X-ray tube assembly and pinching off the second end of vacuum tube to seal the vacuum environment.

摘要： A radiation generating apparatus includes: an envelope 1 having a first window 2 through which a radiation is transmitted; and a radiation tube 10 being held within the envelope 1, and having a second window 15 which is arranged in opposition to the first window 2, and through which the radiation is transmitted; and a radiation shielding member 16 thermally connected to the second window 15, having a radiation transmitting hole 21 arranged in communication with the second window 15, and having a protruding portion protruding from the second window 15 toward the first window 2. A thermally conductive member 17 having a higher thermal conductivity rather than that of the radiation shielding member 16 is connected to the protruding portion of the radiation shielding member 16. The radiation generating apparatus can shield an unnecessary radiation and cool a target with a simple structure and is entirely reduced in weight.

摘要： Disclosed herein are a high-voltage generator for an x-ray source, an x-ray gun, an electron beam apparatus, a rotary vacuum seal, a target assembly for an x-ray source, a rotary x-ray emission target, and an x-ray source. These various aspects may separately and/or together enable the construction of an x-ray source which can operate at energies of up to 500 kV and beyond, which is suitable for use in commercial and research x-ray applications such as computerised tomography. In particular, the high-voltage generator includes a shield electrode electrically connected intermediate of a first voltage multiplier and a second voltage multiplier. The electron beam apparatus includes control photodetectors and photo emitters having a transparent conductive shield arranged therebetween. The rotary vacuum seal includes a pumpable chamber at a position intermediate between high-pressure and low-pressure ends of a bore for a rotating shaft. The rotary target assembly is configured such that when a torque between a bearing housing and a vacuum housing exceeds a predetermined torque, the bearing housing rotates relative to the vacuum housing. The rotary x-ray emission target has a plurality of target plates supported on a hub, the plates being arranged on the hub to provide an annular target region about an axis rotation of the hub. The x-ray gun is provided with a shield electrode maintained at a potential difference relative to the x-ray target different to the electron beam emission cathode.

摘要： A radiation generating apparatus of the present invention includes an envelope 1 including a first window 2 allowing radiation to pass; a radiation tube 10 that is accommodated in the envelope 1, and includes a second window 15 allowing radiation to pass, at a position opposite to the first window 2; a radiation passing hole 21 that is thermally connected to the second window 15 and communicates with the second window 15; and a radiation shielding member 16 protruding from the second window 15 toward the first window 2. In this apparatus, a thermally conductive member 17 having a higher thermal conductivity than the radiation shielding member 16 is connected to an outer periphery of the protruding portion of the radiation shielding member 16. The simple configuration can shield unnecessary radiation, and cool the target, while facilitating reduction in weight.

摘要： Described herein is an x-ray backscatter apparatus (10/100/109) for nondestructive inspection of a part (110). The apparatus includes an x-ray emitter (12) and a zone plate (102). The x-ray emitter (12) includes an x-ray shield (24), a vacuum tube (28), a cathode (30), and an anode (32). The x-ray shield (24) has an emission aperture (26). The vacuum tube (28) is within the x-ray shield (24). The cathode (30) and anode (32) are enclosed within the vacuum tube (28). The cathode (30) generates an electron emission. The anode (32) is located relative to the cathode (30) to receive the electron emission and convert the electron emission to a hard x-ray emission and is located relative to the emission aperture (26) to direct at least a portion of the hard x-ray emission through the emission aperture. The zone plate (102) is external to the x-ray shield (24) and located relative to the emission aperture (26) to receive the portion of the hard x-ray emission and focus the portion into a focused hard x-ray emission.

A method of utilizing different regions of an x-ray tube target by tilting an x-ray tube window at an acute angle with respect to an electron beam axis to cause an electron beam to impinge on a selected region of the window and tilting the window in a different direction to allow the electron beam to impinge on a different selected region of the window.
