X-ray generator of open type

Abstract

For eliminating a high-tension cable in order to improve the handling, the open type X-ray generating apparatus (1) in accordance with the present invention employs a mold power unit (14) in which a high-voltage generating part (15), a grid connecting line (32), and a filament connecting line (33) which attain a high voltage (e.g., 160 kV) are molded with a resin, whereas the mold power unit (14) is secured to the proximal end side of a tubular portion (2), whereby an apparatus of a type integrated with a power supply is realized. Since the high-voltage generating part (15), grid connecting line (32), and filament connecting line (33) are confined within the resin mold as such, the degree of freedom in structure of the high-voltage generating part (15) and the degree of freedom in bending the lines (32, 33) improve remarkably.

Description

technical field [0001] The present invention relates to an open type X-ray generator, and more particularly to an open type X-ray generator in which a consumable filament part can be replaced by vacuum suction of a vacuum pump. Background technique [0002] Conventionally, Japanese Patent Application Publication No. 10-503618 is known as a technique in this field. In the X-ray generating device described in this gazette, the electron beam emitted from the cathode is emitted with the focus formed on the target by the electromagnetic action of the coil, and then the X-ray beam is irradiated to the object to be inspected. Here, since the X-ray generating device operates at a very high voltage of 160KV, it is necessary to additionally equip a large high-voltage power supply device, which is connected to the X-ray generating device via a high-voltage cable. [0003] However, since the high-voltage power supply device driving the X-ray generator is constructed to generate extreme...

Problems solved by technology

That is, the high-voltage cable has very little bending freedom due to its high-voltage characteristics and structure, and care must be taken to prevent disasters caused by leakage in the connection to the X-ray generating device. Carry out regular maintenance, which is a strong excessive burden on the operator or user

Furthermore, the weight of the high-voltage cable is also a factor that further increases the burden on the operator.

[0004] In addition, the X-ray generating device that the power supply part is molded with epoxy resin is disclosed in the Japanese Patent Opening No. 58-14499, but this X-ray generating device is a sealed type, and the method of generating a vacuum by a vacuum pump is not possible.
