ELECTRON COLLECTOR WITH THERMAL INSERT
An electron collector for an x-ray tube having an electron collector base and an electron collector insert. The electron collector insert may be composed of a thermally enhanced material and is used to mitigate thermal stress from the electron collector. The electron collector insert may further prevent cracking and thermal fatigue of the electron collector.
X-RAY TUBE ASSEMBLY
According to one embodiment, an X-ray tube assembly includes a cathode emitting electrons, an anode target generating X-rays when the electrodes emitted from the cathode collide with the anode target, an anode block, a coolant pipe, and a protective film. The anode block includes a tube portion, and a bottom portion closing one end side of the tube portion and joined to the anode target. The coolant pipe is located on an inner side of the tube portion, includes an outlet from which a coolant is discharged toward the bottom portion, and forms a flow passage of the coolant between the coolant pipe and the anode block. The protective film covers an inner surface of the bottom portion and is formed of hard gold containing nickel.
X-Ray Tube with Distributed Filaments
An x-ray generating unit includes an x-ray tube that is substantially transparent to x-rays and that defines a vacuum therein. A cathode is disposed within the x-ray tube and defines a plurality of spaced apart cavities. An anode is spaced apart from the cathode and includes a material that emits x-rays when impacted by electrons. A plurality of filaments is each disposed in a different one of the cavities defined by the cathode and each is electrically coupled to the cathode. Each filament emits a focused electron beam directed to a different predetermined spot on the anode upon application of a predetermined voltage between the cathode and the anode, thereby causing the anode to generate x-rays.
X-RAY GENERATION APPARATUS
An X-ray generation apparatus includes an electron gun configured to emit an electron beam, a rotary anode unit having a target generating an X-ray by receiving the electron beam and configured to rotate the target, a magnetic lens having a coil configured to generate a magnetic force acting on the electron beam between the electron gun and the target, and a wall portion disposed between the target and the coil so as to face the target. The wall portion is formed with an electron passage hole through which the electron beam passes and a flow path configured to allow a coolant to flow.
