Analytical tokamak equilibrium for shaped plasmas
A general analytical solution of the Grad–Shafranov equation is presented. Specific functional forms of pressure and plasma current are used; the solution allows arbitrary plasma size, aspect ratio,Expand

Observation of zero current density in the core of jet discharges with lower hybrid heating and current drive.
Simultaneous current ramping and application of lower hybrid heating and current drive (LHCD) have produced a region with zero current density within measurement errors in the core ( r/a< or =0.2) ofExpand

H-mode pedestal scaling in DIII-D, ASDEX Upgrade, and JET
Multi device pedestal scaling experiments in the DIII-D, ASDEX Upgrade (AUG) and JET tokamaks are presented in order to test two plasma physics pedestal width models. The first model proposes aExpand

Confinement transitions in TJ-II under Li-coated wall conditions
This paper presents the latest results on confinement studies in the TJ-II stellarator. The inherently strong plasma– wall interaction of TJ-II has been successfully reduced after lithium coating byExpand

The formation and evolution of extreme shear reversal in JET and its influence on local thermal transport
In JET discharges where lower hybrid heating and current drive (LHCD) is applied early during the current ramp, a region of the plasma with zero current density is formed near the axis. At theExpand

Global and pedestal confinement in JET with a Be/W metallic wall
Type I ELMy H-mode operation in JET with the ITER-like Be/W wall (JET-ILW) generally occurs at lower pedestal pressures compared to those with the full carbon wall (JET-C). The pedestal density isExpand
