Abstract

A one-dimensional, two-species numerical-simulation code has been used to study the formation and structure of collisionless electrostatic shocks formed by two colliding plasmas and by a plasma striking a perfectly reflecting piston. Collisionless shocks are formed in hydrogen up to a maximum piston velocity of $M \equiv \frac{v_{D}}{c_{S}} \sim 3.5$ . Shocks with velocities up to $M \sim 4$ have been produced which have a predominantly laminar structure accompanied by strong collisionless dissipation.
