Abstract

We discuss numerical interpolation schemes used in Vlasov codes. An improved conservative semi-Lagrangian scheme is compared with the latest non-conservative and conservative schemes for a long run-time nonlinear problem of the beam–plasma interaction with respect to the mass and energy conservation.
