If the ion drift velocity in an inhomogeneous magnetic field depends on the radius, the ion and Varma flute waves can turn out to be damped. This damping is due to a resonant interaction of the waves with the ion drift motion. It may be this physical phenomenon which interfered with the external excitation of waves in certain previous experiments (V. A. Chuyanov and E. G. Murphy, Nucl. Fusion 12, 177 (1972); W. Calvert et al., Preprint CLM-P 293, Culham Lab., 1971). In the present paper numerical methods are used to determine how the damping factor for the ion and Varma branches of the flute waves depends on the plasma density, the inhomogeneity of the magnetic field, and the ion transverse-energy dispersion.
