摘要：

Electron temperatures in excess of 8 keV have been obtained by electron-cyclotron-resonance heating on FTU plasmas at peak densities up to 8 x 10(19) m(-3). The magnetic shear in the plasma core is low or negative, and the electron heat diffusivity remains at, or below, the Ohmic level (0.2 m(2)/s), in spite of the very large heating power density (10-20 MW/m(3)) which produces extremely high temperature gradients (up to 120 keV/m). The ion heat transport remains at the neoclassical level. [S0031-9007(98)08217-9].
