OSTI ID:6912147
A computer model for lower hybrid current drive has been developed which combines a radial transport code, a Fokker Planck solver, and a toroidal ray tracing code. The physical mechanism in the model which allows incident lower hybrid wave power at high parallel phase velocity to eventually interact with lower phase velocity electrons and thus form a significant quasilinear plateau, is the toroidal upshift that occurs in the parallel wavenumber. The resulting rf current generation and its dependency on toroidal magnetic field agree well with experiment.
