β¦ Synopsis
A new conservative gyrokinetic Vlasov code is developed using a finite difference operator which conserves both the L1 and L2 norms. The growth of numerical oscillations is suppressed by conserving the L2 norm, and the code is numerically stable and robust in a long time micro-turbulence simulation. In the slab ion temperature gradient driven (ITG) turbulence simulation, numerical properties of the new code are discussed, and the results are benchmarked against a conventional df particle-in-cell (PIC) code.

A new scheme for solving the Vlasov equation using a phase space grid is proposed. The algorithm is based on the conservation of the flux of particles, and the distribution function is reconstructed using various techniques that allow control of spurious oscillations or preservation of the positivit
