Abstract:
In an x-ray generating apparatus in which x-rays emitted from laser plasma formed by condensing and irradiating a laser beam on and to a target in a vacuum, are taken out from at least one side out of the laser beam irradiation side of the target and the side thereof opposite to said laser beam irradiation side,said x-ray generating apparatus comprising:a strong magnetic field generating means for generating a magnetic field component substantially vertical with respect to the target surface in the vicinity of said laser plasma,said magnetic field component being arranged to generate a magnetic force which acts directly on charged particles in said laser plasma to bend the tracks of said charged particles, causing said charged particles to be confined in a magnetic field formed by said magnetic field component,the magnetic flux of a strong magnetic field formed by said strong magnetic field generating means, is directed to the direction in which said laser plasma is generated,an x-ray supply object is disposed in a direction different from said laser plasma generating direction, andcharged particles liable to be directed to said x-ray supply object are mainly confined in said strong magnetic field, wherein said target is disposed at the center of said strong magnetic field formed by said strong magnetic field generating means.
