Notes:
Finite Larmor radius (FLR) magnetohydrodynamic equations for stellarators are solved numerically to study the linear mode structure of the drift interchange mode. FLR stabilization correlates with the reduction of the phase difference between the pressure perturbation (or the magnetic perturbation) and the potential perturbation. In a cylindrical plasma model with a fixed boundary, the FLR effect, however, is found to destabilize the interchange mode in the large diamagnetic drift velocity regime.
