Abstract
Helicon wave sustained discharges provide high density plasmas needed to investigate Alfvén waves under laboratory conditions. In the present paper kinetic Alfvén waves were successfully launched in a helium plasma. A good agreement is found between the measured and the theoretically predicted dispersion behaviour. The damping can be associated both to collisional and Landau damping.
