Hypocycloidal pinch device

Claim 2

A hypocycloidal pinch device comprising three spaced apart, coaxially aligned, annular electrodes where a middle electrode is disposed between two outer electrodes; means for containing said spaced apart electrodes; a first ring disposed between said middle electrode and one of said outer electrodes at the approximate outer edges thereof; a second ring disposed between said middle electrode and the other one of said outer electrodes at the approximate outer edges thereof, said first and second rings being respectively connected to said outer electrodes; means for insulating the first and second rings from the middle electrode, said insulating means comprising first and secnd insulative annular discs respectively disposed on the upper and lower surfaces of said middle electrode at the approximate outer edge thereof, said first and second rings respectively contacting said first and second insulative annular discs, the inner diameter of said discs being less than the inner diameter of said rings and greater than the inner diameter of said middle electrode; means for charging said containing means with a working gas; and means for applying pulsed electrical energy between (a) said outer electrodes and (b) said middle electrode to thereby initially produce a first plasma of said working gas in the vicinity of the inner edge of said first annular insulative disc across said first ring and the approximate outer edge of the upper surface of said middle electrode and a second plasma of said working gas in the vicinity of the inner edge of said second annular insulative disc across said second ring and the approximate outer edge of the lower surface of said middle electrode, said first and second plasmas being radially transferred and compressed to the inner edge of said middle electrode where they are brought together along the axis of said electrodes and further compressed into a single dense plasma.

Claim 3

A device as in claim 1 where said three electrodes comprise a module and a plurality of modules are coaxially aligned in a said container.

Claim 4

A device as in claim 2 where adjacent end electrodes of successive modules are respectively disposed on opposite faces of a common element.

Claim 5

A device as in claim 1 including source means for projecting a beam of a first energy type into said plasma to produce therefrom a second energy type.

Claim 6

A device as in claim 4 where said source means comprises an electron or laser beam source and said second energy type is an X-ray beam.

Claim 7

A hypocycloidal pinch device comprising three spaced apart, coaxially aligned, annular electrodes where a middle electrode is disposed between two outer electrodes; means for containing said spaced apart electrodes; a first ring disposed between said middle electrode and one of said outer electrodes at the approximate outer edges thereof; a second ring disposed between said middle electrode and the other one of said outer electrodes at the approximate outer edges thereof, said first and second rings being respectively connected to the upper and lower surfaces of said middle electrode; means for insulating the first and second rings from the outer electrodes, said insulating means comprising first and second insulative annular discs respectively disposed on the inner surfaces of said outer electrodes at the approximate outer edges thereof, said first and second rings respectively contacting said first and second insulative annular discs, the inner diameter of said discs being less than the inner diameter of said rings and greater than the inner diameter of said middle electrode; means for charging said containing means with a working gas; and means for applying pulsed electrical energy between (a) said outer electrodes and (b) said middle electrode to thereby initially produce a first plasma of said working gas in the vicinity of the inner edge of said first annular insulative disc across said first ring and the approximate outer edge of the inner surface of said one outer electrode and a second plasma of said working gas in the vicinity of the inner edge of said second annular insulative disc across said second ring and the approximate outer edge of the inner surface of said other outer electrode, said first and second plasmas being radially transferred and compressed to the inner edge of said middle electrode where they are brought together along the axis of said electrodes and further compressed into a single dense plasma.

Claim 8

A hypocycloidal pinch device comprising three spaced apart, coaxially aligned, annular electrodes where a middle electrode is disposed between two outer electrodes; means for containing said spaced apart electrodes; a first ring disposed between said middle electrode and one of said outer electrodes at the approximate outer edges thereof; a second ring disposed between said middle electrode and the other one of said outer electrodes at the approximate outer edges thereof, said first and second rings being respectively connected to the upper and lower surfaces of said middle electrode; means for insulating the first and second rings from the outer electrodes, said insulating means comprising first and second insulative annular discs respectively disposed on the inner surfaces of said outer electrodes at the approximate outer edges thereof, said first and second rings respectively contacting said first and second insulative annular discs, the inner diameter of said discs being less than the inner diameter of said rings and greater than the inner diameter of said middle electrode; means for charging said containing means with a working gas; and means for applying pulsed electrical energy between (a) said outer electrodes and (b) said middle electrode to thereby initially produce a first plasma of said working gas in the vicinity of the inner edge of said first annular insulative disc across said first ring and the approximate outer edge of the inner surface of said one outer electrode and a second plasma of said working gas in the vicinity of the inner edge of said second annular insulative disc across said second ring and the approximate outer edge of the inner surface of said other outer electrode, said first and second plasmas being radially transferred and compressed to the inner edge of said middle electrode where they are brought together along the axis of said electrodes and further compressed into a single dense plasma.
