Abstract in Portuguese
Neste trabalho apresentamos o estudo da possivilidade de melhores regimes para o uso dos experimentos de aquecimento e geracao de corrente e fluxo de plasma no tokamak TCABR. Apresentamos um estudo dos efeitos de rotacao de plasma em baixa frequencia (low-frequency (LF)), penetração de campo eletromagnético, absorção e forças ponderomotoras no “Tokamak Chauffage Alfvén Brésilien” (TCABR) com ênfase na faixa de frequências de 0, 5–10, 0kHz. Os campos de LF são dirigidos pelo limitador magnético ergódico (ergodic magnetic limiter (EML)) no TCABR. Foi feito um estudo analítico das ondas de Alfvén e ressonância usando modelos simples. Um estudo num´erico tembém foi realizado utilizando três códigos, quais sejam, o código cinético toroidal, o código cilíndrico e o código ALTOK.

Abstract in English
In this work we present the study of the determination the best regimes and parameters¶for the heating experiments and current generation and plasma flow in the tokamak TCABR. Study of effects of plasma rotation in low frequency (LF), field penetration, absorption and ponderomotive forces in “Tokamak Chauffage Alfvén Brésilien” (TCABR)is investigated with emphasis in the frequency range of 0, 5–10, 0kHz. The fields of LF are driven by the ergodic magnetic limiter (EML) in TCABR. A qualitative analytical study of the Alfvén waves and their resonances is performed using simple models. A numeric study was carried out using through three codes, called the kinetic totoidal code, the cylindrical code and the ALTOK code.
