Abstract :
Simulations of the plasma wakefield accelerator are carried out by following the time evolution of the plasma distribution function in one dimension via the Vlasov-Maxwell equations. It is found that highly nonlinear wakes are obtainable in the vicinity of the driving beam, where the thermal velocity spread of the plasma is reduced. In this region, wake amplitudes can significantly exceed the expectations of relativistic warm plasma models and agree closely with cold fluid theory.<>
