Abstract
The present invention discloses a system and method for generating a beam of fast ions. The system comprising: a target substrate having a patterned surface, a pattern comprising nanoscale pattern features oriented substantially uniformly along a common axis; and; a beam unit adapted for receiving a high power coherent electromagnetic radiation beam and focusing it onto said patterned surface of the target substrate to cause interaction between said radiation beam and said substrate enabling creation of fast ions.

A system for generating a beam of fast ions, the system comprising:
- a target substrate having a patterned surface, a pattern comprising nanoscale pattern features oriented substantially uniformly along a common axis;
- and;
- a beam unit adapted for receiving a high power coherent electromagnetic radiation beam and focusing it onto said patterned surface of the target substrate to cause interaction between said radiation beam and said substrate enabling creation of fast ions.
A method for generating fast ions, comprising irradiating a target substrate with a high power polarized coherent electromagnetic radiation beam, wherein the target substrate has a patterned surface with a pattern comprising nanoscale pattern features oriented substantially uniformly along a common orientation axis;
- and wherein a relation between said pattern and at least one parameter of the electromagnetic radiation is optimized by selecting at least one of an angle between a polarization direction of the beam of electromagnetic radiation and the orientation axis, and an incident angle for said beam of electromagnetic radiation, such that interaction between said radiation beam and said patterned surface of the substrate provides an efficient coupling between said radiation beam and said substrate resulting in generation of a fast ions' beam.
