What is it about?

In this paper, we have discussed a computational scheme for the simulation of particle wakefield accelerations (PWFA) processes. This scheme adopts a fluid description of the problem, and solves the warm relativistic fluid dynamic equations of the plasma wake generated by a driver pulse propagating in a neutral plasma. The relativistic kinetic equations are closed by adopting the two most popular assumptions of the field, the local equilibrium and the warm plasma closure assumptions.

Why is it important?

The developed LB schemes can, thus, be used to disclose insights on the quantitative differences between the two closure approaches in the dynamics of PWFA processes. Comparisons between the proposed schemes and available analytical results are extensively addressed.
