Claim Text:
1. A system for generating a beam of fast ions, the system comprising; a target substrate having a patterned surface, a pattern comprising sub-resonant nanowires laid on a substrate, the nano-wires have a diameter substantially smaller than the wavelength λ of a laser used to irradiate the target substrate and a length greater than at least 1λ; and a beam unit adapted to receive a high power coherent electromagnetic radiation beam and to focus it onto the patterned surface of the target substrate to cause interaction between the high power coherent electromagnetic radiation beam and the target substrate with a patterned surface configured to create a flow of fast ions; and wherein the patterned surface of the target substrate acts as a field concentrator for the electric field of the electromagnetic radiation interacting with the pattern; and wherein the nano-wires of the patterned surface of the target substrate, characterized by a direction of orientation, are constructed and arranged to concentrate and amplify the coherent electromagnetic radiation beam electric field at their ends.
