ABSTRACT:
A source for a high density electrically neutral beam of combined positive and negative particles suitable for bombardment and heating of a pellet of nuclear fusion material to fusion temperature. A source mounted in a housing with a spherical substrate having positive ion emitter material thereon, first, second and third grids spaced from each other along the beam path, and electron emitters, for providing positive ion beams and electron beams at the same velocity for mixing to provide an overall electrically neutral beam. A source utilizing a zeolite type compound, such as B-eucryptite or sodium mordenite, which on heating emits positive ions of an element in the compound, such as lithium or sodium. A source housing including precision ceramic rings with metal flanges, with substrate and grid structures carried on the flanges, with the flanges joined as by heliarc welding at their peripheries to provide a rigid mechanical and vacuum tight structure, with metal spacer rings between ceramic rings when desired.
