Magnetic end closures for plasma confining and heating devices

Claim 1

IN AN OPEN-ENDED DEVICE FOR THE MAGNETIC CONFINEMENT AND HEATING OOF PLASMA TO HIGH KINETIC TEMPERATURES AND HAVING AT KEAST MEANS FOR ESTABLISHING IN AN EVACUATED SPACE A REACTION ZONE DEFINED BY A MAGNETIC CONFINEMENT FIELD REGION FOR NUCLEAR REACTIONS BETWEEN THE CONSISTUENTS OF GASEOUS PLASMA THEREIN, THE IMPROVEMENT COMPRISING MEANS INCLUDING A PLURALITY OF SOLENOIDS SPACED IN GENERALLY COXIAL PARALLEL ALIGNMENT AND DISPOSED IN EACH OF THE OPPOSITE END REGIONS OF SAID REACTION ZONE FOR GENERATING THEREIN AN AXIALLY SYMMETRIC MAGNETIC FIELD HAVING A PLURALITY OF AXIALLY SPACED NODAL REFLECTOR FIELD REGIONS OF INCREASED MAGNETIC INTENSITY TERMINALLY BOUNDING SAID REACTION ZONE AND DEFINING A PLURALITY OF CHARGED PARTICLE TRAPPING CELLS OF LESSER INTENSITY INTERPOSED BETWEEN SAID REFLECTOR FIELD REGIONS, SAID SOLENOIDS BEING SPACED SO THAT THE NODAL FIELDS GENERATED THEREBY ARE SUCHCESSIVELY SPACED TO BE AT LEAST ABOUT THE MEANS FREE PATH DISTANCE OF INTERPARTICEL COLLISONS IN SAID CHARGES PARTICLE TRAPPING CELLS WHEREBY THE PROBILITY THAT PARTICEL ESCAPING AXIALLY FRON THE REACTION ZONE THROUGH THE INNERMOST REFLECTOR FIELD REGIONS WILL SUCESSIVELY PENETRATE ALL OF SAID REFLECTOR FIELF REGIONS IS LOW, AND MORE EFFECTIVE CONFINEMENT OF THE PLASMA IS ATTAINED.
