PROBLEM TO BE SOLVED: To continuously generate a uniform X-ray in a laser plasma X-ray source generating a hard X-ray by impressing a high voltage. SOLUTION: In the laser plasma X-ray source generating X-ray by irradiation with laser light, a pair of electrodes impressing a high voltage between the electrodes are provided, and on the opposite side of the other electrode 22 over a wall constituted by the electrode 23 on one side of the electrode pair, a continuously moving electrode material 24 and a moving mechanism 25 are placed to irradiate the surface of the electrode material 24 with laser light in the constitution. Two cylindrical electrodes with different inner sizes are contained and an electrode pair for impressing high voltage between them are provided and other electrode 23 is placed in the cylinder of the one electrode 22. Furthermore, a pair of continuously moving electrodes 24 and a moving mechanism 25 are placed in the cylinder of other electrode 23. Owing to the suppression of electromagnetic damages, the suppression of adhesion of dispersed material and improvement in the electric characteristics between the electrodes, uniform X-ray can be continuously generated. |
