介绍了阿尔卡托托卡马克毫米波波动辐射的测量结果。其特点是：(1)调制速度快，上升时间为3 - 4 μsec，接近100%；(2)线宽非常窄，等离子体频率<5 GHz;(3)强度非常大，可达200倍热。这些特征将这种辐射与先前记录的稳定ωpe发射区分开来，并被解释为表明静电振荡的非线性转换为辐射的起源。
Measurements are presented of fluctuating millimeter‐wave radiation from the Alcator tokamaks. Its characteristics are (1) rapid modulation, approaching 100% with rise time 3–4 μsec, (2) very narrow line width, <5 GHz at the plasma frequency, and (3) extremely large intensity, up to 200 times thermal. These characteristics distinguish this radiation from the steady ωpe emission previously documented and are interpreted as indicating nonlinear conversion of electrostatic oscillations as the origin of the radiation.
