    摘要： To obtain high-directivity, stable, and high-intensity ion beam.An ion beam irradiator 10 is constituted by a combination of a laser-driven ion/electron generator 20 and an ion transporter 30 and is configured to guide ion beam with low directivity emitted from the ion/electron generator 20 to the output end while increasing the directivity of the ion beam or focusing the ion beam at the ion transporter 30. In the ion transporter 30, an electron absorber 33 is provided around a beamline 31 at a location on the upstream side in terms of the flow of the ion beam relative to multipole magnets 32. The electron absorber 33 is formed of a material (e.g., polytetrafluoroethylene (PTFE)) that can effectively absorb high-energy electrons. The electron absorber 33 is surrounded by an X-ray shield 34 made of heavy metal such as lead.

    摘要： A laser-driven particle beam irradiation apparatus includes: a particle beam generator irradiating a target with pulsed laser light to emit a laser-driven particle ray; a beam converging unit forming a transportation path which guides the emitted laser-driven particle ray to an object and spatially converging the laser-driven particle ray; an energy selector selecting an energy and an energy width of the laser-driven particle ray; an irradiation port causing the laser-driven particle ray to scan the object to adjust an irradiation position in the object; and an irradiation controller controlling operation of the particle beam generator, the beam converging unit, the energy selector and the irradiation port. The beam converging unit generates a magnetic field on a trajectory of the laser-driven particle ray and converging the laser-driven particle ray by the magnetic field, the magnetic field forcing divergence components of the laser-driven particle ray that go away from a center of the trajectory back to the center of the trajectory.
