摘要: An x-ray tube casing is provided which includes a central frame having internal passages to supply a cooling fluid directly to the casing without the need for an external dedicated heat exchanger. The cooling fluid flowing through the passages in the easing can thermally contact the dielectric coolant within the casing to cool the tube coolant during operation of the x-ray tube. The casing is formed in an additive manufacturing process to allow for tight tolerances with regard to the structure for the casing and the internal passages to reduce the size and weight of the casing. The casing can additionally be formed from a metal matrix including a metal with high x-ray attenuation and a filler metal. The metal matrix eliminates the need for a separate x-ray attenuation layer within the casing, further reducing the size, number of parts and assembly complexity of the casing.

摘要: An X-ray source for ionizing of gases includes a field emission tip array within a vacuum region enclosed by a hood and a part of a support plate. The field emission tip array is arranged electrically insulated with respect to the carrier plate and wired as a cathode connected to a high-voltage source. A transmission window transparent to X-ray radiation is arranged in the hood centrally above the field emission tip array, and the hood is wired as an anode.

摘要: In the present invention, a ferroelectric body is irradiated with ultraviolet light, and the ferroelectric body is caused to stably generate electric potential. A method for radiating charged particles, in which the UV-light-receiving surface of the ferroelectric body that receives UV light and is caused to generate a potential difference is irradiated with UV light having a wavelength not transmitted by the ferroelectric body, and charged particles are radiated from the charged-particle-radiation surface of the ferroelectric body, wherein the UV-light-receiving surface is irradiated with pulses of UV light at a peak power of 1 MW or greater. The pulse width of the UV light is measured in picoseconds (less than 1×10−9 seconds), and the UV pulses can be transmitted by fiber.
