This paper covers specific electrical and thermal aspects of the radio-frequency (RF) circuit which supplies the ion source of the International Thermonuclear Experimental Reactor (ITER) Neutral Beam Injector (NBI). Firstly, a matching circuit for the RF Antennas is presented and a possible solution for the matching components discussed, in relation to the anticipated equivalent circuit parameters of the RF driven plasma. Secondly, the thermal behaviour of the RF transmission line is analyzed, utilising finite element tools, to evaluate the RF line overtemperature under the heaviest foreseen operating conditions. © 2009 A.
