Abstract

Ion cyclotron modes were excited in a low density, cylindrical plasma cavity using an external inductive antenna. These modes, which have a long parallel wavelength, exhibit a strong electrostatic character and are only weakly coupled to the antenna fields. The measured wavefields are compared to those predicted by a theory that takes account of the effect of electron dynamics. It is shown that electron Landau damping and electron inertia play an important role in determining the cavity mode structure.
