Computer simulations of magnetosonic waves, velocity-shell instabilities, and upper-hybrid heating show evidence of a general damping mechanism for large-amplitude electrostatic waves propagating perpendicular to a magnetic field: Particles trapped by a wave of frequency ..omega.. and phase velocity V/sub ph/ see an electric field V/sub ph/ x B, which accelerates them parallel to the wave front until the v x B force is large enough for detrapping. For ..omega..>>..omega../sub c/, velocities as large as (..omega../4..omega../sub c/)V/sub ph/ can be attained, within a time ..omega../sub c/troughly-equal..omega../4..omega../sub c/.
