The high poloidal-beta (β P) regime was first proposed as a high bootstrap current scenario
for a steady-state fusion pilot plant (FPP) in the 1990s (Kikuchi in Nucl Fusion 30: 265 …

The tokamak approach, utilizing a toroidal magnetic field configuration to confine a hot
plasma, is one of the most promising designs for developing reactors that can exploit …

Stability at high beta (the ratio of plasma pressure to magnetic field pressure) is an important
requirement for a compact, economically attractive fusion reactor. It is also important in …

An artificial neural network, combining signals from a large number of plasma diagnostics,
was used to estimate the high-beta disruption boundary in the DIII-D tokamak. It is shown …

Magnetic diagnostics are essential for the operation and understanding of a magnetic fusion
device. Magnetic data are used in real time to measure and control the current, shape, and …

The global energy confinement of combined ohmic and lower hybrid driven TORE SUPRA
plasmas has been analysed at various densities. In contradiction to the L mode ITER scaling …

Research on the stability of spherical torus plasmas at and above the no-wall beta limit is
being addressed on the National Spherical Torus Experiment [M. Ono et al., Nucl. Fusion 40 …
