托卡马克的反常电子输运定标律

本文假设导致托卡马克反常电子输运的主要机制为由温度梯度所驱动的重整化电子磁漂移波。通过求解动力学过程自洽地导出了反常电子输运系数的定标律:D^(T)=(c/ω_pe)²{((v_e/qR)²/2π+(v_{c/2)²)^1/2-vc/2}。它在数值上与现有实验给出的AIcator定标律符合。在无碰撞(vc→0)情况下与Ohkawa定标津一致。同时分析了该定标律与Alcator定标律的偏离,并由此讨论了强磁场欧姆加热托卡马克达到热核点火的可能性。 关键词：}

A SCALING LAW FOR THE ANOMALOUS ELECTRON TRANSPORT IN TOKAMAKS

It is assumed in the paper that the dominant mechanism for the anomalous electron transport in Tokamaks is the renormalized electron magnetic drift wave driven by temperature gradient. A scaling law for the anomalous electron transport coefficient D^(T) has been derived by solving self -consistently the kinetic process, it reads D^(T)=(c/ω_pe)² {((v_e/qR)²/2π+(v_{c/2)²)^1/2 - vc/2} It coincides in numerical values with the Alcator scaling law given by the Tokamak's experiments, and it agrees with the Ohkawa scaling law in the collisionless limit (vc → 0). Furthermore, its deviation from the Alcator scaling law is analyzed, and the possibility of achieving the thermonuclear ignition for a high-field ohmically heating Tokamak is also discussed based on the scaling law.}
