The detailed identification is presented for two instabilities driven by an ion beam injected parallel to the confining magnetic field, a resonant ion cyclotron instability and a nonresonant ion cyclotron drift wave driven by the beam's density gradient. Experimental results are in good agreement with numerical calculations based on the kinetic Vlasov equations. Quasi-linear velocity space diffusion of the beam ions by wave-particle interaction is observed, demonstrating enhanced energy transfer. The relevance of these results to Tokamak neutral beam injection heating is discussed.
