The kinetic structure of slow magnetosonic shocks obtained from 1- and 2-D hybrid (fluid electrons, particle ions) simulations is discussed. The magnetic structure of the shock varies considerably with the Mach number. At low Mach numbers, the shock may be laminar with no associated waves, whereas, at high Mach numbers the shock may be unsteady with Alfvenic turbulence in the upstream and the downstream regions. The nature of ion dissipation also varies with the Mach number. At weak laminar shocks, ion dissipation consists of adiabatic heating and reflection of a small number of ions back into the upstream. At stronger shocks, particle scattering by Alfven/ion-cyclotron waves in the upstream contributes to the heating which continues well into the downstream region.
