本文综述了TFTR血浆转运的研究进展。超热离子的平行输运和限制被发现是相对较好的理论描述。跨场运输的热等离子体，然而，是异常的动量扩散率是可比的离子热扩散率和大于中性束加热放电中的电子热扩散率。微扰实验研究了输运系数的非线性依赖关系，并研究了可能的非局部现象的作用。基本的湍流已经研究了使用微波散射，束发射光谱和微波反射在一个更广泛的范围内k垂直于比以前可能的。结果表明，存在与增强运输的大波长波动。
A review of TFTR plasma transport studies is presented. Parallel transport and the confinement of suprathermal ions are found to be relatively well described by theory. Cross-field transport of the thermal plasma, however, is anomalous with the momentum diffusivity being comparable to the ion thermal diffusivity and larger than the electron thermal diffusivity in neutral beam heated discharges. Perturbative experiments have studied nonlinear dependencies in the transport coefficients and examined the role of possible nonlocal phenomena. The underlying turbulence has been studied using microwave scattering, beam emission spectroscopy and microwave reflectometry over a much broader range in k perpendicular to than previously possible. Results indicate the existence of large-wavelength fluctuations correlated with enhanced transport.
