Pullback transformation in gyrokinetic electromagnetic simulations
- Max Planck Institute for Plasma Physics, D-17491 Greifswald (Germany)
It is shown that a considerable mitigation of the cancellation problem can be achieved by a slight modification of the simulation scheme. The new scheme is verified, simulating a Toroidal Alfvén Eigenmode in tokamak geometry at low perpendicular mode numbers, the so-called “MHD limit.” Also, an electromagnetic drift mode has been successfully simulated in a stellarator.
