Abstract
LARGE HIGH ENERGY DEUTERIUM NEUTRAL BEAMS WHICH MUST BE MADE FROM NEGATIVE IONS REQUIRE EXTENSIVE MAGNETIC SHIELDING AGAINST THE INTENSE FRINGING FIELDS SURROUNDING A MAGNETIC FUSION POWER PLANT. CONVENTIONAL SHIELDING BY IRON, STEEL, OR ALLOYS LEAD TO EITHER LOW SATURATION LIMITS OR BECOME EXCESSIVELY MASSIVE. IT IS PROPOSED THAT MULTILAYER SHEETS OF COPPER-SUPERCONDUCTING LAMINATED MATERIAL, REINFORCED BY NONMAGNETIC STAINLESS STEEL SUPPORT, WILL PROVIDE THE NECESSARY SHIELDING FOR NEUTRAL BEAMS AND SHOULD WITHSTAND THE MAGNETICALLY INDUCED FORCES. A FEASIBILITY STUDY OF THE DESIGN, MATERIAL CHARACTERISTICS, STRENGTH ANALYSIS, FABRICATION TECHNIQUES, SUBSCALE TEST DEFINITIONS, AND ECONOMICS OF THIS SUPERCONDUCTING SHIELDING TECHNIQUE IS THE SUBJECT OF THIS PROPOSAL. IMPROVED MAGNETIC SHIELDING SHOULD RESULT IN CLOSER MOUNTING OF THE NEUTRALIZER TO THE REACTOR AND SMALLER APERTURE REQUIREMENT IN THE REACTOR WALL LEADING TO A MORE COMPACT NEUTRAL BEAM INJECTOR AND SAVING OF FLOOR FLOOR SPACE IN THE VICINITY OF THE REACTOR WHICH IS AT A PREMIUM.
