Cyclotron motion of fusion products (FPs) or other superthermal ions has been shown theoretically to generate ion cyclotron emission (ICE) which is strongly dependent upon the ratio of ion velocity to the background Alfven velocity [C. Chu and J. L.

The dispersion relation for current-driven electromagnetic instabilities in an inhomogeneous slab geometry is derived and analyzed. It is shown that current in the direction of the equilibrium magnetic field, as well as transverse current gradients c

Nonlinear instabilities driven by waves with frequencies comparable to the lower hybrid frequency are examined both analtyically and numerically using particle simulation techniques. Both the oscillating two-stream and ion-cyclotron instabilities are

The relativistic electron annulus is a critical component of the bumpy torus magnetic fusion concept. An analysis of the annulus is presented in which the ring steady state is determined by the explicit balance of quasi-linear heating and classical l

In many plasma-magnetic-field configurations, the ion skin depth is comparable to magnetic field and density-gradient scale lengths and so inhomogeneity must play an important role for wave propagation in the ion-cyclotron range of frequencies. As an
