PFC / JA - 93 - 12 Fast Wave Flow Drive in a Two - Component Plasma with Low Minority Concentration

PFC / JA - 93 - 19 Plasma Heating by Fast Magnetosonic Waves in Tokamakst

The fundamental theory of plasma heating by the fast magnetosonic wave in toroidal plasma configurations is reviewed and extended. The particular wave damping processes considered include cyclotron damping at the fundamental ion cyclotron frequency and its harmonics, and electron Landau damping and transit time magnetic pumping (TTMP). The latter processes heat electrons and may also be exploit...

Pfc/ja-93-6 Lower Hybrid Current Drive in the Presence of Ion Cyclotron

PFC / JA - 89 - 57 ICRF - Edge Plasma Interaction Studies at MIT

The Alcator C-Mod experiment will study high power ICRF heating of elongated, diverted plasmas at high density in a compact, high field tokamak. ICRF heating will be carried out in the minority heating regime by fast wave excitation in a deuterium plasma with a 'He or H minority. Because of compact size of the tokamak, high loading will be required to couple the power at acceptable voltages and...

PFC/RR-92-13 Current-Drive and Plasma-Formation Experiments on the Versator-Il Tokamak Using Lower-Hybrid and Electron-Cyclotron Waves

During lower-hybrid current-driven (LHCD) tokamak discharges with thermal electron temperature Te ~~ 150 eV, a two-parallel-temperature tail is observed in the electron distribution function. The cold tail extends to parallel energy Ell ~ 4.5 keV with temperature Tthd ~ 1.5 keV, and the hot tail extends to El > 150 keV with Thj' > 40 keV. Fokker-Planck computer simulations suggest the cold tail...
