In Heliotron E, a plasma is produced and heated only by an electron cyclotron resonance wave (f = 28 GHz). The output power and pulse width are up to 90 kW and 40 ms, respectively. The parameters of the plasma are in a wide range (Te = 0.3−1.1 keV and e = (1.2−9.5) × 1018m×3). The dependence of the electron temperature on the microwave output power indicates no saturation of the electron temperature. A preliminary analysis is also presented which indicates that the absorption efficiency may be rather good. The anomaly factor, which is the ratio of the experimental particle diffusion to the neoclassical value in the plateau regime, is 2 to 6 for the case of medium density (about 5 × 1018m−3).

ヘリオトロンEにおいて、プラズマは電子サイクロトロン共鳴波(f = 28 GHz)のみによって生成・加熱される。出力パワーとパルス幅はそれぞれ最大90 kWおよび40 msである。プラズマのパラメータは広い範囲にわたる(Te = 0.3−1.1 keVおよびe = (1.2−9.5) × 1018m×3)。電子温度のマイクロ波出力パワーへの依存性は、電子温度の飽和がないことを示している。また、吸収効率がかなり良好である可能性を示す予備的解析も提示されている。プラトー領域における実験的な粒子拡散と新古典論的値との比である異常係数は、中程度の密度(約5 × 1018m−3)の場合において2から6である。
