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: 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 emitting target including a diamond substrate, a first layer disposed on the diamond substrate and including a first metal, and a second layer disposed on the first layer and including a second metal whose atomic number is 42 or more and which has a thermal conductivity higher than that of the first metal. Carbide of the first metal is present at a boundary between the diamond substrate and the first layer. The target is prevented from overheating, so that output variation due to rising temperature is suppressed. Thus it is possible to emit stable and high output X-rays.

Abstract: In a radiation source and a method for the generation of X-radiation, a liquid is arranged in a liquid line, the liquid being completely surrounded by the liquid line in the direction of an evacuated chamber. A portion of the liquid line is permeable to an electron beam such that the electron beam extending through the chamber is able to enter via the liquid line so as to interact with the liquid in an interaction zone for the generation of X-radiation. The radiation source ensures a good dissipation of heat from the interaction zone and prevents liquid from entering the chamber.
