This paper reviews the research on the reversed field pinch (RFP) in the last three decades.
Substantial experimental and theoretical progress and transformational changes have been …

Transport is the outstanding physics issue in the quest for fusion by magnetic confinement.
In spite of the intrinsic difficulty, a great deal of progress has been made in the past 25 years …

Positive radial electric fields have been created at the edge of the TEXTOR tokamak plasma
using an electrode. The electric field induces a thin (δr∼ 1.5 cm), E× B driven layer at the …

Reduction of core-resonant m= 1 magnetic fluctuations and improved confinement in the
Madison Symmetric Torus [Dexter et al., Fusion Technol. 19, 131 (1991)] reversed-field …

Improved confinement has been achieved in the MST through control of the poloidal electric
field, but it is now known that the improvement has been limited by bursts of an edge …

In the Madison Symmetric Torus1 MST reversed-field pinch RFP, we have measured the
plasma flow velocity fluctuations v with a fast, high-resolution spectrometer, the magnetic …

First measurements of temperature fluctuations in a region of high velocity shear show that
absolute and normalized fluctuation levels are reduced across the shear layer, a result that …

The scaling of the magnetic and velocity fluctuations with Lundquist number (S) is examined
experimentally over a range of values from 7× 10 4 to 10 6 in a reversed-field pinch (RFP) …

Optimization of machine operation, including plasma position control, density control and
especially feedback control on multiple magnetohydrodynamic modes, has led RFX-mod to …

In the reversed-field pinch (RFP), tearing modes associated with the dynamo are
responsible for reduced energy-and particle confinement. In this study, it is observed that by …
