RESUMO

Current drive by lower hybrid wave LH, is the most promising technique to obtain continuos current for the controlled thermonuclear fusion. The existence of "Spectral gap" forbid satisfactory match between theoretical results and experimental measurements of the generated current. The theory has always predicted smaller values. In this Thesis we show a possible solution for the spectral gap, by a numerical code which calculate the generated current by LH waves, using the "Quasi1inear Fokker-Planck" equation in two dimensions, taking in to account detai1s of ressonance between particles and the longitudinal LH waves and its spectral distribution
