Query: Accuracy of unperturbed motion of particles in a gyrokinetic
  semi-Lagrangian code   Inaccurate description of the equilibrium can yield to spurious effects in
gyrokinetic turbulence simulations. Also, the Vlasov solver and time
integration schemes impact the conservation of physical quantities, especially
in long-term simulations. Equilibrium and Vlasov solver have to be tuned in
order to preserve constant states (equilibrium) and to provide good
conservation property along time (mass to begin with). Several illustrative
simple test cases are given to show typical spurious effects that one can
observes for poor settings. We explain why Forward Semi-Lagrangian scheme bring
us some benefits. Some toroidal and cylindrical GYSELA runs are shown that use
FSL.
