Steady plasma flows in a periodic non-symmetric domain
Harold Weitzner, Wrick Sengupta
Steady plasma flows have been studied almost exclusively in systems with continuous symmetry or in open domains. In the absence of continuous symmetry, the lack of a conserved quan…
Vacuum magnetic fields with exact quasisymmetry near a flux surface. Part 1: Solutions near an axisymmetric surface
Wrick Sengupta, Elizabeth J. Paul, Harold Weitzner +1
While several results have pointed to the existence of exactly quasisymmetric fields on a surface (Garren & Boozer 1991a,b; Plunk & Helander 2018), we have obtained the first such…
Charged particle dynamics near an X-point of a non-symmetric magnetic field with closed field lines
E. Elbarmi, W. Sengupta, H. Weitzner
Understanding particle drifts in a non-symmetric magnetic field is of primary interest in designing optimized stellarators to minimize the neoclassical radial loss of particles. Qu…
Exact non-symmetric closed line vacuum magnetic fields in a topological torus
Harold Weitzner, Wrick Sengupta
Non-symmetric vacuum magnetic fields with closed magnetic field lines are of interest in the construction of stellarator equilibria. Beyond the result of D.Lortz (ZAMP \textbf{21},…
Low-shear three-dimensional equilibria and vacuum magnetic fields with flux surfaces
Wrick Sengupta, Harold Weitzner
Stellarators are generically small current and low plasma beta () devices. Often the construction of vacuum magnetic fields with good magnetic surfaces is the startin…
Radial confinement of deeply trapped particles in a non-symmetric magnetohydrodynamic equlibrium
Wrick Sengupta, Harold Weitzner
Quasisymmetry and omnigeneity of an equilibrium magnetic field are two distinct properties proposed to ensure radial localization of collisionless trapped particles in any stellara…
