METHOD AND DEVICE FOR GENERATING A FOCUSED STRONG-CURRENT CHARGED-PARTICLE BEAM

摘要

A method for generating a focused filled particle beam comprising (a) generating a filled particle beam (10, b) emitting a laser pulse (40, 0); (c) A focusing magnetic field structure (50) is generated in the target () through the interaction between the laser pulse and the target, and (d) at least partially penetrates the filled particle beam into the focused magnetic field structure.
