讨论了 TFTR L 模式和超爆状态下的托卡马克能量限制尺度。主要结果是 TFTR L 模式等离子体符合能量限制的超激发缩放定律。在这两种情况下，等离子体传输系数随着边缘氘流入的增加而增加。 TFTR 上常见的 L 模式限制比例定律也与加热到高温的壁材料的体积成反比，高温可能是材料中吸附的氘被脱出并高度流动的温度。氘流入量的增加是由于：(a) 由于边缘部件中的加热深度更深而导致束功率增加，以及 (b) 由于润湿面积增加而导致等离子体电流减少，这取决于经验观察到的 SOL 宽度对等离子体电流的依赖性。
Tokamak energy confinement scaling in TFTR L mode and supershot regimes is discussed. The main result is that TFTR L mode plasmas fit the supershot scaling law for energy confinement. In both regimes, plasma transport coefficients increased with increased edge deuterium influx. The common L mode confinement scaling law on TFTR is also inversely proportional to the volume of wall material that is heated to a high temperature, possibly the temperature at which the deuterium sorbed in the material becomes detrapped and highly mobile. The deuterium influx is increased by: (a) increased beam power due to a deeper heated depth in the edge components and (b) decreased plasma current due to an increased wetted area as governed by the empirically observed dependence of the SOL width upon plasma current.
