摘要：

A new theory of microwave reflectometry is applied to turbulence measurements in the TFTR tokamak. Results indicate that in the main core of neutral beam heated plasmas in the supershot regime, the radial correlation length of density fluctuations is a weak decreasing function of heating power in the range 2-4 cm. Over the same interval of heating powers (0-14 MW), the level of density fluctuations is observed to steadily increase by more than an order of magnitude.
