Perturbative analysis of low-frequency instabilities in high-field ST40 experiments
Nuclear Fusion, 2023 Linear and nonlinear perturbative analyses of low-frequency instabilities are presented for ST40 spherical torus high field plasmas, with simultaneous neutral beam heating due to two tangential sources at 25 keV and 55 keV.

Effects of CT injector acceleration electrode configuration on tokamak penetration [PDF]
, 1998 Through compact toroid (CT) injection experiments on the TEXT-U tokamak (with BT simeq 10 kG and IP simeq 100 kA), it has been shown that the acceleration electrode configuration, particularly in the vicinity of the toroidal field (TF) coils of the ...

On non existence of tokamak equilibria with purely poloidal flow [PDF]
, 2006 It is proved that irrespective of compressibility tokamak steady states with purely poloidal mass flow can not exist in the framework of either magnetohydrodynamics (MHD) or Hall MHD models.

Motion and equilibrium of a spheromak in a toroidal flux conserver [PDF]
, 1991 A number of experiments have been performed on spheromaks injected into the empty vacuum vessel of the Caltech ENCORE tokamak (i.e., without tokamak plasma) [Phys. Rev. Lett. 64, 2144 (1990); Phys. Fluids B 2, 1306 (1990)].
