Numerical simulation of parasitic ion Bernstein wave coupling during fast wave heating
- University of Wisconsin-Madison, Madison, Wisconsin 53706 (United States)
Parasitic coupling to the ion Bernstein wave during fast wave heating is investigated using the WICS computer code. The WICS code models ICRF antenna coupling to tokamak plasmas for phased coil antenna arrays in a recessed cavity. The antenna radiation resistance and the spectrum of the ICRF power coupled to the plasma are calculated. Parasitic coupling to the ion Bernstein wave is shown to be important for low parallel wavenumbers during minority ion heating with large gradients in the plasma density near the edge of the plasma. Results are presented for TFTR antenna and plasma parameters using experimental data. {copyright} {ital 1996 American Institute of Physics.}
