Antenna-plasma coupling theory for ICRF heating of large tokamaks

Technical Report ·
OSTI ID:6084915

The radiation impedance of, and field excitation by, current sheets external to a large (minor radius) plasma are calculated. The finite-size antenna current modeled by these current sheets is screened from the plasma by a sheath of anisotropic conductivity which shorts out locally the toroidal rf electric field but does not affect the poloidal rf electric field. The plasma near the antenna is modeled by its cold dielectric tensor having an inhomogeneous density and applied magnetic field. The field analysis for the coupling and power flow is carried out in a slab geometry.
