しかし、上記従来技術によると、アルミニウム材及ヒア
ルミニウム・プラズマのレーザー光線反射率が高＜、ｘ
ｉの発生効率が低いと言う問題点があった。Conventionally, it has been customary to use aluminum as the target material of the laser plasma x, Ijl source.・High plasma laser beam reflectance <, x
There was a problem that the generation efficiency of i was low.
本発明は、かかる従来技術の問題点をなくし、レーザー

ト材表面に形成する事（含炭素膜）等の手段をとる。In order to solve the above problems, the present invention provides a laser/plasma X-ray source that (1) uses carbon as the target material, and (2) coats the surface of the target material with a polymeric organic coating containing carbon as a constituent element. (carbon-containing film).
以下、本発明の実施例を第１図により詳述する。 Hereinafter, embodiments of the present invention will be described in detail with reference to FIG.

の波長のｘｉＩが２０％以上の効率で発生する。In this way, when carbon is used as the target material in a laser plasma Xg source, the light reflection of carbon and carbon plasma is reduced and the light absorption is increased. 1oX of X-rays is 1
While it occurs with an efficiency of about 0%, 10X to 100X
xiI of wavelength is generated with an efficiency of more than 20%.
