Paramagnetic Solovév equilibrium with flow

A Solovév-like equilibrium with arbitrary incompressible plasma flow nonparallel to the magnetic field is identified. The equilibrium configuration having a corner on the axis of symmetry resembles the nonlinear Palumbo one. The nonparallel flow associated with the quantity λ∝d/du[ρ(dΦ/du)2]λ∝d/du[ρ(dΦ/du)2] (where ρ is the density, Φ the electrostatic potential and u   labels the magnetic surfaces) affects the plasma shape, the Shafranov shift and the safety factor. For λ<0λ<0 the equilibrium has an x  -point additional to the magnetic axis and increase of |λ||λ| results in a variety of configurations with changing magnetic topology.

► Novel extended paramagnetic Solovév equilibrium with nonparallel plasma flow. ► The configuration has a corner on the axis of symmetry. ► The flow affects appreciably the shaping and confinement figures of merit. ► Decreasing elongation does not imply reversed magnetic shear profiles. ► The nonparallel component of the flow can change the magnetic field topology.
