Abstract
Abstract THERMONUCLEAR REACTOR UTILIZING A MAGNTIC COIL STRUCTURE INCLUDING A PAIR OF INTERMESHED C-SHAPED ELECTROMAGNETIC COILS (YIN-YANG CONFIGURATION) TO PRODUCE A MAGNETIC CONFINEMENT ZONE. PLASMA IS PRODUCED IN A PULSED PLASMA SOURCE AND IS DIRECTED BY MAGNETIC FIELDS INTO THE REGION OF SAID CONTAINMENT ZONE. A TRAPPING FIELD IS PRODUCED BY MEAND OF A SECOND PAIR OF C-SHAPED ELECTROMAGNET COILS ENCOMPASSING THE FIRST SET TO TRAP PLASMA IN SAID REGION. THE FIRST SET OF COILS IS THEN ENERGIZED TO CONTAIN AND COMPRESS THE TRAPPED PLASMA THEREBY DENSIFYING AND HEATING THE PLASMA TO A HIGH TEMPERATURE.
