High-power neutral injection and ion power balance in TFR

Equipe TFR1978年被引用 56Nuclear FusionIF 3出版社

A fast-neutral power of up to 570 kW has been injected into TFR. At low densities (e ≅ 2–3 × 1013 cm−3), the central ion temperature was doubled to 2 keV as a result of the injection. The ion temperature increases linearly with the injected power. Macroscopic perturbations due to the injected power yield information on the ion behaviour and the ion energy confinement time. There are indications, that the ion heat conduction might be anomalous. Effects of neutral injection on equilibrium, stability, and impurity concentration are discussed.

TFRに最大570kWの高速中性粒子パワーが入射された。低密度(e ≅ 2–3 × 10^13 cm−3)では、入射の結果、中心イオン温度は2倍の2 keVとなった。イオン温度は入射パワーとともに線形に増加する。入射パワーによる巨視的摂動は、イオンの挙動とイオンエネルギー閉じ込め時間に関する情報を与える。イオン熱伝導が異常である可能性を示す兆候がある。平衡、安定性、および不純物濃度に対する中性粒子入射の影響について議論する。
