A global plasma turbulence simulation code, ORB5, is presented. A particular feature is the use of straight-field-line magnetic coordinates and a field-aligned Fourier filtering technique that dramatically improves the performance of the code in terms of both the numerical noise reduction and the maximum time step allowed. Another feature is the capability to treat arbitrary axisymmetric ideal MHD equilibrium configurations. The code is validated against an analytical theory of zonal flows and against other codes for a selection of linear and nonlinear tests.
