OVERVIEW OF ECRH EXPERIMENTAL RESULTS

A review of the present status of electron cyclotron heating and curre nt drive experiments in toroidal fusion devices is presented. In addit ion to basic heating and current drive studies the review also address es advances in wave physics and the application of electron cyclotron waves for instability control, transport studies, pre-ionization/start -up assist, etc. A comprehensive overview is given with particular emp hasis on recent advances since the major review of Erckmann and Gaspar ino (1994) (Plasma Phys. Control. Fusion 36 1869), including results f rom the latest generation of high-power, high-frequency experiments.
