The typical MHD disruption at safety factor {ital q}{sub {ital a}}=3 has been suppressed by off-central electron cyclotron heating with power of 70--80 kW in the JFT-2M tokamak. For the suppression, the electron cyclotron resonance layer has to be pl

The characteristics of the edge localized model (ELM), also referred to as edge relaxation phenomenon, were investigated in H-mode plasmas of JFT-2M. It was found that the ELM is mainly a density fluctuation phenomenon at the edge and that the electr

The effects of plasma edge modification on confinement have been investigated on the JFT-2M tokamak since 1985. In the course of investigations, a new enhanced confinement regime, limiter H-mode, was discovered in 1986. This paper is a review of inve

In JFT-2M, impurity behaviors during the H-mode were studied by the spectroscopic method. During the H-mode without Edge-Localized Modes (ELMs), emissions of highly ionized ion lines increased with time, although emissions of less ionized ion lines d

The coupling characteristics of the fast wave excited by a phased four-loop antenna array are described. Fast waves in the lower hybrid frequency range have the potential of generating plasma current in hot and dense plasmas. Fast waves are excited a

The effect of the longitudinal electrostatic field on the energy conversion efficiency is investigated by use of a 1-dimensional FEL amplification code. It is found that the repulsive electrostatic interaction prevents the periodic bounce motion of t

The roles of the edge plasma are investigated with respect to impurity release, antenna loading, and H-mode transition. Metal impurity release is considered to be caused by an RF electric field near the antennas, and can be reduced by the out-of-phas

Intense pulse electron cyclotron heating (ECH) experiments have been carried out on the MTX tokamak. Rf pulses at 140 GHz with peak power of 1–2 GW and 25 ns pulse length were generated by the ETA‐II/IM FEL and transported quasi‐optically to MT
