Abstract
Abstract A gas or vapor is ionized by passing it through a plasma jet, hydrogen plasma for example; the ionization takes place in an enclosure, the wall of which either contains devices for injecting the gas or vapor to be ionized, or devices for vaporizing by local heating solid samples of the same substance.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A system for producing high intensity ion beams by electric charge exchange reactions between a plasma beam and a chemical material, comprising a duoplasmatron device for production of said plasma beam, a reaction expansion chamber in which said Charge exchange takes place, said chamber having on a side a wall separating it from said duoplasmatron device, said wall having an orifice for the introduction of said plasma beam, means for introducing said chemical material in gaseous form into said chamber, and there being on the opposite side of said chamber an output wall with an orifice for the exit of the reaction products created in said chamber, said expansion chamber being dimensioned for allowing said beam to expand as a bubble, and means, downstream said output orifice, for extracting from said reaction products a pure ion beam of said chemical material.
Claim 2
Independent Claim
141 words
A system for producing high intensity ion beams by electric charge exchange reactions between a plasma beam and a chemical material, comprising a duoplasmatron device for production of said plasma beam, a reaction expansion chamber in which said Charge exchange takes place, said chamber having on a side a wall separating it from said duoplasmatron device, said wall having an orifice for the introduction of said plasma beam, means for introducing said chemical material in gaseous form into said chamber, and there being on the opposite side of said chamber an output wall with an orifice for the exit of the reaction products created in said chamber, said expansion chamber being dimensioned for allowing said beam to expand as a bubble, and means, downstream said output orifice, for extracting from said reaction products a pure ion beam of said chemical material.
Claim 3
Dependent Claim
22 words
A system as claimed in claim 1, in which said introducing means is formed by a tubular duct, opening into said chamber.
Claim 4
Dependent Claim
34 words
A system as claimed in claim 2, in which at least the wall portion of said reaction chamber, facing the opening of said tubular duct into said chamber, is formed by a refractory material.
Claim 5
Dependent Claim
28 words
A system as claimed in claim 1, in which said introducing means is a cavity located in a wall of said chamber, wherein said chemical material is placed.
Claim 6
Dependent Claim
38 words
A system as claimed in claim 1, in which said introducing means is a cavity located in a wall of said chamber, wherein said chemical material is placed and means for heating said chemical material to vaporize it.
Claim 7
Dependent Claim
38 words
A system as claimed in claim 5, in which said heating means is an electron source placed in front of at least a portion of said chamber wall and raised to a negative potential with respect to it.
