Reduction in neutral beam driven current in a tokamak by tearing modes
Published Web Locationhttps://doi.org/10.1103/PhysRevLett.79.427
Profiles of noninductive current driven by neutral beam injection into a tokamak have been measured and compared with theory. The driven current can be less than the theoretical prediction (by up to 80%) in the presence of islands driven by tearing modes. © 1997 The American Physical Society.
