The High-Beta Tokamak equilibrium code
^{[1]}
^{[2]}
is based on a somewhat unusual technique (in the field of MHD equilibrium calculations), namely conformal mapping theory.
^{[3]}
Using this technique, the (arbitrarily shaped) cross section of the last closed flux surface is mapped to a circular disk, greatly facilitating the solution of equilibrium and stability problems.
