PFC / JA - 96 - 39 ICRF Heating Scenarios on Alcator C - Mod

PFC / JA - 96 - 9 Survey of ICRF Heating Experiments and Enhanced Performance Modes in Alcator C - Mod

Results of ICRF heating experiments in Alcator C-Mod during the November 1994 June 1995 campaign are summarized. Efficient heating of high density ( , ; 3 x 1020 m-3 ) plasmas was demonstrated with high power densities (up to 5 MW/m 3 volume averaged, 0.6 MW/m 2 surface averaged). These experiments were carried out with RF powers up to 3.5 MW at 80 MHz, at magnetic fields up to 8 T and plasma c...

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 / JA - 96 - 29 H Mode Confinement in Alcator C - Mod

A series of experiments, examining the confinement properties of ICRF heated H-mode plasmas, has been carried out on the C-Mod tokamak. C-Mod is a compact tokamak which operates at high particle, power, and current densities at toroidal fields up to 8T. Under these conditions the plasma is essentially thermal with very little contribution to the stored energy from energetic ions (typically no m...

ICRF Heating in Alcator C-Mod:

Alcator C-Mod, the high field, high density, diverted, compact tokamak in the world's portfolio of high performance plasma fusion devices, is heated exclusively with ICRF auxiliary power. In this paper an overview of recent results is summarized, with particular attention given to the importance of RF operation and the flexibility afforded by different heating scenarios. Besides the routine min...
