Quasisymmetry

Quasisymmetric (quasihelically symmetric) plasma equilibria are non-axisymmetric configurations in which the magnetic field strength depends only on one angular coordinate within the magnetic flux surfaces.

An example of quasisymmetry is quasipoloidal symmetry, on which the design of the QPS stellarator is based.
