Abstract

Deuterium neutral beams with energies up to 110 keV were injected into TFTR (Tokamak Fusion Test Reactor) plasmas at low magnetic field such that the beam injection velocities were comparable to the Alfv\'en velocity. Excitation of toroidal Alfv\'en eigenmodes was observed by Mirnov coils and beam emission spectroscopy.
