Abstract

The current drive potential by the negative-ion-based neutral beam injector is investigated for International Tokamak Reactor (INTOR) benchmark test parameters. To estimate the current drive profile, the a beam current drive analysis code is used. The code is composed of the two-dimensional Fokker-Planck and the three-dimensional beam power/momentum deposition calculations. In most cases, the 500-keV injection energy is assumed except for the beam energy scanning, and the 500-keV beam feasibility in the INTOR design is clarified. The beam current drive potential is also discussed for transformer recharging in quasi-steady-state operations. Fast alpha-particle pressures are discussed, taking into account the beam-plasma direct deuterium-tritium reaction.
