Abstract

A LH simulation code has been used to simulate elongated plasmas with numerically generated equilibra. The model includes ray tracing using a dispersion relation with electromagnetic and thermal effects and the solution of a 1D Fokker‐Planck equation with quasi‐linear diffusion on each radial surface. Results are presented for a study of LH drive in ITER. (AIP)
