By application of electron cyclotron heating (ECH) to the WT-2 tokamak, the high-frequency instability (relaxation oscillation) excited by the lower-hybrid-wave-driven current is suppressed and the loop voltage decreases without voltage spikes, implying that the driven current increases. This suppression can be ascribed to the isotropization of the current-carrying beam electrons by ECH.

WT-2トカマクへの電子サイクロトロン加熱(ECH)の適用により、低混成波駆動電流によって励起される高周波不安定性(緩和振動)が抑制され、ループ電圧のスパイクを伴わずにループ電圧が低下する。これは駆動電流の増加を示唆するものである。この抑制は、ECHによる電流担持ビーム電子の等方化に帰属することができる。
