Focuses on the Electric Tokamak (ET), which is under construction at the University of California-Los Angeles (UCLA). Design of the ET to rotate poloidally via a radial current induced by fast wave; Bifurcation of the plasma into a global high confinement mode; Use of a gyrokinetic code; Effects on ion temperature gradient turbulence.

Describes numerical solutions of Zakharov-type equations for lower-hybrid (LH) waves, including pumping at the long wavelengths and dissipation at short wavelengths in the form of dissipative cavitons. Quasistationary structure undergoing many sequences of collapse due to dissipation; Ion-wave interactions; Possibility of trapping of short-wavelength LH oscillations.

Examines the collisional heating rate of a fully ionized plasma driven by a strong electromagnetic pump wave, both analytically and with two-dimensional particle-in-cell simulations. Extension of the high frequency conductivity model of Dawson and Oberman to large values of both quiver velocity; Expression for the collision frequency in terms of complicated integrals.
