An analysis of the neutral beam (NB) current drive for the International Thermonuclear Experimental Reactor (ITER) is performed. The NB deposition profile for a model elliptic equilibrium is evaluated for arbitrary density profiles. Multistep ionization is accounted for. The NB current density is calculated by using an approximate solution of the Fokker-Planck equation. A parameter scan is performed by changing electron density, plasma temperature, the plasma effective ionic charge Zeff, beam energy Eb, beam mass number, beam section, and tangency radius of the beam center. The largest values of the current drive figure of merit γNB = INBnR/P are obtained for the largest beam energy. The obtained value of γNB for the ITER reference scenario is γNB = 0.6 for Eb = 1.3 MeV and Zeff = 2.
