• It is shown by theory and a relativistic, electromagnetic particle simulation that strong ion acceleration occurs in a fast magnetosonic shock wave; the maximum speed of trapped ions can be about (m_i/m_e)^1/2 times as large as the Alfven speed in a quasiperpendicular shock. The acceleration takes place even in laminar shock waves. The magnitude of the acceleration increases with ω_ce/ω_pe and is enhanced by finite beta effects. For a parameter regime ω_ce/ω_pe≳ 1,highly relativistic ions and electrons are produced simultaneously in the shock ramp. The structure of a nonlinear slow wave and associated resonant ion acceleration is also discussed.
