Ion wave excitation for the study of wave-induced transport
A general programme to study wave-particle interactions and wave-induced transport in a low temperature, low density collisionless plasma has led to the application of an assortment of ion wave launching schemes. Attention now focuses on the problem of stochastic interaction with two ion cyclotron modes. A detailed knowledge of the waves excited by the antenna will allow a selection of mode phase velocities such that the separation of wave-particle resonances can be controlled. In this way, the wave field amplitudes necessary for reaching the stochasticity threshold can be reduced, in comparison to the situation with one wave. This paper reviews the wave dispersion characteristics compiled during these wave-particle interaction studies. The plasma dispersion relation universally determines the wave response, quite independent of the antenna configuration.
