The area of energetic particle (EP) physics in fusion research has been actively and
extensively researched in recent decades. The progress achieved in advancing and …

The pursuit of steady-state economic production of thermonuclear fusion energy has led to
research on the stabilization of the external kink and the resistive wall mode. Advances in …

As part of the ITER Design Review and in response to the issues identified by the Science
and Technology Advisory Committee, the ITER physics requirements were reviewed and as …

Stabilizing modes that limit plasma beta and reduce their deleterious effect on plasma
rotation are key goals for the efficient operation of a fusion reactor. Passive stabilization and …

The JT-60SA device has been designed as a highly shaped large superconducting tokamak
with a variety of plasma actuators (heating, current drive, momentum input, stability control …

Repetitive bursting instabilities with strong frequency chirping occur in high-beta, beam-
heated plasmas with safety factor q> 1 in the DIII-D tokamak. Although the mode structures …

Externally applied, non-axisymmetric magnetic fields form the basis of several relatively
simple and direct methods to control magnetohydrodynamic (MHD) instabilities in a …

A stability analysis for the resistive wall mode is studied in the presence of trapped energetic
particles (EPs). When the EPs' beta exceeds a critical value, a fishbonelike bursting mode …

This paper describes the prediction of disruptions based on diagnostic data in the high-β
spherical torus NSTX (Ono et al 2000 Nucl. Fusion 40 557). The disruptive threshold values …

Active feedback control in the DIII-D tokamak has fully stabilized the current-driven ideal kink
resistive-wall mode (RWM). While complete stabilization is known to require both low …
