Long-wavelength (k_₈1) density turbulence has been measured with good spatial localization in the core region of a high temperature tokamak plasma with auxiliary heating. Density fluctuations of n \~/n>0. 5% exist for k_2 cm^-1 with radial and poloidal correlation lengths typically 1--2. 5 cm in the confinement region, corresponding to k_₈0. 1--0. 3. An anisotropic wave-number spectrum is observed, and estimates of the turbulence-driven transport are comparable to the anomalous transport observed in tokamaks.
