Description
【発明の詳細な説明】 本発明はＸ線源装置に関する。[Detailed description of the invention] The present invention relates to an X-ray source device.
従来、Ｘ線発生装置は銅等の水冷、回転ターゲ
ツトに電子線を照射して特性Ｘ線を得る方法が用
いられていた。 Conventionally, X-ray generators have used a method of obtaining characteristic X-rays by irradiating an electron beam onto a water-cooled, rotating target such as copper.
しかし、上記従来技術では高輝度のＸ線が得ら
れないという欠点がある。 However, the conventional technique described above has a drawback in that high-intensity X-rays cannot be obtained.
本発明はかかる従来技術の欠点をなくし、高輝
度のＸ線を得ることを目的とする。 The present invention aims to eliminate the drawbacks of the prior art and obtain high-intensity X-rays.
上記目的を達成するための本発明の基本的な構
成は、石英、セラミツク等絶縁材からなる中空容

ズマをピンチさせる事を特徴とする。 The basic structure of the present invention to achieve the above object is that two electrodes are attached to a hollow container made of an insulating material such as quartz or ceramic, and
A gas such as Ar is filled, and an electric field and current are applied to the gas by the electrode to create a plasma state, and a coil or magnet is provided outside the container to apply a magnetic field to the plasma. It is characterized by pinching plasma.
以下実施例を用いて本発明を具体的に説明す
る。 The present invention will be specifically described below using Examples.

る。 Electrodes 2 and 3 are provided at both ends of a container 1 made of quartz, and Ar gas is put into the container 1. By inputting AC or DC power to the electrodes 2 and 3, the Ar gas is turned into plasma. state. When a magnetic field is applied to the plasma by a coil 4 or the like from outside the container 1, the plasma causes a pinch phenomenon,
High-intensity X-rays (λ≒10〓) are generated and radiated to the outside through a window 5 made of Be attached to the container 1.
この様にガス・プラズマの外部磁界によるピン
チ効果を用いてＸ線源とすることにより高輝度の
Ｘ線源を得ることができる効果がある。 In this way, by using the pinch effect of gas plasma as an X-ray source due to the external magnetic field, it is possible to obtain a high-intensity X-ray source.
尚、本実施例では容器を閉方式としたが、容器
内のガスは絶えず供給しながら真空ポンプにより
吸引し、内部圧力を一定に保つ方式を用いても良
い。 In this embodiment, the container is closed, but a method may also be used in which the gas inside the container is constantly supplied and suctioned by a vacuum pump to keep the internal pressure constant.
