Title:
LASER-ACCELERATED PARTICLE BEAM DEVICE AND LASER-ACCELERATED PARTICLE BEAM GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/162391
Kind Code:
A1
Abstract:
The present invention provides a laser-accelerated particle beam device and a laser-accelerated particle beam generation method which achieve a reduction in fluctuation of a light focusing position when an irradiation angle is changed. To this end, provided is a laser-accelerated particle beam device (10) that generates a particle beam by exciting a target (15, 21) with laser light, said laser-accelerated particle beam device comprising an aperture mask (12) that has an aperture that allows part of the laser light to pass therethrough, and a concave mirror (14) that reflects the laser light which has passed through the aperture of the aperture mask and causes the laser light to converge at a focal point (F0) set within the target, wherein the aperture mask is movable in a direction that intersects the laser light which passes through the aperture mask.
