Abstract

Abstract The instant invention involves a system for generating high current density charged particle beams. The system includes a plurality of high intensity ion sources in combination with two charge exchange cells aligned linearly with one another. The ions are converted from one type of charge to an opposite charge in two stages. In the first stage, several beams of positive ions, for example, derived from a plurality of positive ion sources are beamed into a charge exchange cell and converted into neutrals. The several beams of neutrals from the first cell are then directed into a second charge exchange cell where the neutrals are converted into negative ions.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 94 words
A system for generating a high current density charged particle beam comprising: a plurality of ion sources for generating a plurality of charged particle beams; means for neutralizing most of the ions of each of said charged particle beams generated by each of said plurality of ion sources; and means for ionizing a portion of the neutralized ions of the beams coming from said means for neutralizing, said plurality of ion sources and said means for neutralizing being arranged such that said neutralized particle beams converge into and intersect at said means for ionizing.
Claim 2
Independent Claim 94 words
A system for generating a high current density charged particle beam comprising: a plurality of ion sources for generating a plurality of charged particle beams; means for neutralizing most of the ions of each of said charged particle beams generated by each of said plurality of ion sources; and means for ionizing a portion of the neutralized ions of the beams coming from said means for neutralizing, said plurality of ion sources and said means for neutralizing being arranged such that said neutralized particle beams converge into and intersect at said means for ionizing.
Claim 3
Dependent Claim 16 words
An apparatus in accordance with claim 1 wherein said ion sources generate positively charged particle beams.
Claim 4
Dependent Claim 16 words
An apparatus in accordance with claim 1 wherein said ion sources generate neGatively charged particle beams.
Claim 5
Dependent Claim 24 words
An apparatus in accordance with claim 1 wherein said means for ionizing is adapted to convert said neutralized beams to negatively charged particle beams.
Claim 6
Dependent Claim 24 words
An apparatus in accordance with claim 1 wherein said means for ionizing is adapted to convert said neutralized beams to positively charged particle beams.
Claim 7
Dependent Claim 24 words
An apparatus in accordance with claim 2 wherein said means for ionizing is adapted to convert said neutralized beams to negatively charged particle beams.
Claim 8
Dependent Claim 24 words
An apparatus in accordance with claim 2 wherein said means for ionizing is adapted to convert said neutralized beams to positively charged particle beams.
Claim 9
Dependent Claim 24 words
An apparatus in accordance with claim 3 wherein said means for ionizing is adapted to convert said neutralized beams to positively charged particle beams.
Claim 10
Dependent Claim 24 words
An apparatus in accordance with claim 3 wherein said means for ionizing is adapted to convert said neutralized beams to negatively charged particle beams.
