Abstract
Abstract A population inversion is established by beam foil excitation. A beam of completely stripped nuclei is passed through a foil target. An ion beam travels between the plates of a strip transmission line in a plane parallel to those plates. The foil is located in a slot in one of the plates. A voltage pulse is applied at the downstream end of the line and a wavefront propagates down the plates towards the upstream end. This pulse will cause deflection of the ion beam towards the foil along a linear intersection path which travels at approximately the velocity of light.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
79 words
A system comprising first means producing a beam of stripped nuclei; a thin hydrogen rich foil strip target means having a length; and second means connected to the target means and positioned to the beam of stripped nuclei consisting of He + + or Li + + + so as to cause said beam to intersect the target such that intersection of the beam and the target travels the length of said target at substantially the speed of light.
Claim 2
Independent Claim
79 words
A system comprising first means producing a beam of stripped nuclei; a thin hydrogen rich foil strip target means having a length; and second means connected to the target means and positioned to the beam of stripped nuclei consisting of He + + or Li + + + so as to cause said beam to intersect the target such that intersection of the beam and the target travels the length of said target at substantially the speed of light.
Claim 3
Dependent Claim
53 words
A system as set forth in claim 1 wherein said second means comprises first and second transmission line plates aligned parallel to said beam and said target means; third means connected to the ends of said transmission line; and said third means producing a voltage pulse to said plates for deflecting said beam.
