Abstract
Alfven wave propagation in a helicon plasma is being studied in the Auburn Linear Experiment for Space Plasma Investigations. The helicon discharge pr ovides the high-density plasma necessary to propagate Alfven waves. Shear A lfven waves are produced in this discharge by means of an inductive coil po sitioned to oscillate the magnetic field perpendicular to the background fi eld lines. The waves are detected by means of a second inductive coil posit ioned down the plasma column. Initial investigations demonstrate the propag ation of shear Alfven waves within the plasma through the localization of t he oscillations along the magnetic-field lines and the expected phase veloc ity of the waves.
