TY - CONF TI - Analysis of RF and neutral beam heating and current drive in Tokamaks AB - Synergy during simultaneous injection of Lower Hybrid Waves and Fast Waves/Ion Bernstein Waves is studied throughout a 2-D Fokker-Planck code. It is shown that the linear regime holds for both IBW and FW at realistic value of the wave power flux. Synergistic effects are found only for FW and IBW power flux much larger than the LH power flux. Neutral Beam current drive and deposition for a model elliptic equilibrium is investigated, including multi-step ionization and beam particle self-interaction process. A parameter scan is performed for ITER. The largest value for the current drive figure of merit is obtained at the largest beam energy. The propagation of LH waves is investigated analytically and numerically for realistic ITER equilibria. The dependence of wave penetration on elongation and triangularity is discussed.
