The stabilizing role played by trapped electrons and background ions in the excitation of Alfven waves in a two-component tokamak of noncircular cross section is studied. The electron and ion damping rates for Alfven waves in a noncircular tokamak are calculated. At a sufficiently high plasma pressure, the noncircular nature of the tokamak cross section strongly affects the ion damping rate for these waves. A condition for the stabilization of Alfven waves by background ions is derived for two-component tokamaks with cross sections which are ''very elliptical'' or ''very triangular.''
