Figure 6: 3D HKMHD/NIMROD reproduces the FRC transition.
From: Achieving a long-lived high-beta plasma state by energetic beam injection
Contours of plasma pressure in an FRC with a relatively small fast particle concentration from NBI, obtained from HKMHD/NIMROD calculations. (a) In the equilibrium phase before the development of the tilt mode. (b) During the tilt mode at maximum perturbation. (c) In the new quiescent state after tilt perturbation decays away.
