Abstract
Ion-acoustic shock waves are observed experimentally introducing strong Landau damping by increasing the ion temperature in a double plasma device. An oscillatory ion-acoustic shock wave undergoes transition with enhanced Landau damping and forms a monotonic shock wave. Numerical results of the Korteweg–de Vries equation with an additional integral term to account for the strength of Landau damping are compared with the experimental findings. Enhancement of Landau damping is found to increase the dissipation of the wave, which manifests in quenching of the oscillatory structure behind the shock front.
