    Abstract: A radiation generating apparatus includes a target base, a target, an electronic beam generating device, a tube, a tank, and a porous structure. The target is disposed on the target base. The electronic beam generating device is adapted to generate an electronic beam, and the electronic beam is emitted to the target to generate a radiation. The tube accommodates the target and the electronic beam generating device. The tank is connected to the target base and accommodates the tube. The porous structure is roundly disposed between the tank and the tube and contacts an inner wall of the tank and an outer wall of the tube. A cooling fluid flows through the porous structure to dissipate the heat of the porous structure.

    Abstract: An X-ray emitter is suitable for evenly sterilizing large volumes of material in a short time, the emitter having an elongated X-ray target window and correspondingly elongated electron source mounted in a vacuum chamber. The electrons from the electron source are accelerated towards the X-ray target window, which generates X-rays directed outward from the vacuum chamber when irradiated by electrons from within the vacuum chamber. The elongated form of the electron source ensures that an evenly distributed beam of electrons, with a substantially constant linear distribution over the length of the electron source, arrives at the elongated X-ray target window such that a correspondingly even distribution of X-rays is generated from the X-ray target window. The X-ray target window includes a support substrate, and carries an X-ray target layer made of a target material such as tantalum or tungsten on its inner surface. A process for manufacturing the X-ray emitter is also described.

    Abstract: An X-ray module includes a housing in which an opening portion is formed; an electron gun that emits an electron beam; a target that transmits an X-ray generated when the electron beam is incident on the target and emits the X-ray from an X-ray-emitting surface; an X-ray-emitting window that seals the opening portion, and that transmits the X-ray and emits the X-ray to a first side in an axial direction; and a heat radiating unit disposed outside the housing. The housing includes a surface on which a protrusion protruding to the first side is formed, the opening portion is formed in the protrusion, and the target is disposed in the opening portion. The heat radiating unit includes a first portion extending along the surface and thermally connected to the surface, and a second portion extending from the first portion to a second side opposite the first side.
