Application of rf-thruster technique for fusion plasma heating
Abstract
On the basis of RF ion thruster devices, a family of RF injector generators (RIGs) for the heating of fusion plasmas up to the temperature of thermonuclear burn has been developed. Hydrogen ion beams of 10-40 amps can be accelerated by means of the RIGs to 30 kV, so that ion beam densities of more than 250 mA/sq cm are achievable at uniform profiles within only 1 deg of divergence angle. The use of electrodeless quartz ionizers yields a very high atomic ion fraction, low admixture of impurities, long lifetime, high reliability, simple mechanical elements, and easy control.
