antenna array array for the generation of a continuous current in a magnetically confined plasma in a fusion reactor thermonuclear type tokomak through high frequency electromagnetic irradiation

摘要

Disclosed herein is an electromagnetic radiating structure to generate, when supplied with an RF power, a direct current (DC) in a magnetically confined plasma in a thermonuclear fusion reactor of the tokomak type by high frequency electromagnetic radiation, wherein the antenna array comprises an array of mutually coupled poloidal radiators elongated along a poloidal coordinate (y), spaced (d z ) along a toroidal coordinate (z) at a distance (d x ) from a ground surface, and with lengths lower than the wavelength of the radiated electromagnetic waves; and wherein the radiators are so connected to exploit inter-radiator mutual coupling to propagate a supplied RF power across the radiators to cause a toroidally travelling electromagnetic wave to be radiated in the plasma and, resultingly, a toroidal direct current to be induced in the plasma.
