Abstract
Abstract An apparatus for producing neutrons having a base portion, an energy source and a pair of uniquely designed electrodes, one of which is at least partially of titanium. These electrodes are shaped so as to cause a tri-dimensional compression on the plasma or ionized gas within this apparatus. The tri-dimensional compression in conjunction with the titanium electrode provides for higher temperatures and neutron yields than were heretofore possible.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
99 words
A neutron producing apparatus comprising an insulator base, an inner electrode having good conductivity, high evaporation resistance and good hydrogen gettering properties mounted on said base in the center thereof, said inner electrode having a small base portion extending to a flared section adjacent the upper end and becoming hemispherically shaped at the upper end thereof, a parabolically-shaped outer electrode mounted on said base and surrounding said inner electrode, an energy source electrically connecting said inner and outer electrodes and a gas source secured adjacent to said outer electrode for introducing a gas between said inner and outer electrodes.
Claim 2
Dependent Claim
99 words
A neutron producing apparatus comprising an insulator base, an inner electrode having good conductivity, high evaporation resistance and good hydrogen gettering properties mounted on said base in the center thereof, said inner electrode having a small base portion extending to a flared section adjacent the upper end and becoming hemispherically shaped at the upper end thereof, a parabolically-shaped outer electrode mounted on said base and surrounding said inner electrode, an energy source electrically connecting said inner and outer electrodes and a gas source secured adjacent to said outer electrode for introducing a gas between said inner and outer electrodes.
Claim 3
Dependent Claim
32 words
A neutron producing apparatus as defined in claim 1 wherein the space between said electrodes at the upper end is extremely small compared to the space between said electrodes at the base.
Claim 4
Dependent Claim
15 words
A neutron producing apparatus as defined in claim 2 wherein said inner electrode contains titanium.
Claim 5
Dependent Claim
14 words
A neutron producing apparatus as defined in claim 3 wherein said gas is deuterium.
Claim 6
Dependent Claim
25 words
A neutron producing apparatus as defined in claim 4 wherein the diameter of the base of said outer electrode is substantially equal to its height.
Claim 7
Dependent Claim
31 words
A neutron producing apparatus as defined in claim 5 wherein the diameter of the flared section of said inner electrode is at least three times the diameter of its base portion.
Claim 8
Dependent Claim
15 words
A neutron producing apparatus as defined in claim 2 wherein said inner electrode contains zirconium.
