ABSTRACT
Results are presented from experimental studies of the behavior of the plasma ion component during disruptive instability in the TVD and DAMAVAND tokamaks. It is shown that the ion temperature increases during a major disruption by a factor of 1.5–2. The ions are accelerated predominantly across the magnetic field near the rational magnetic surfaces. Results on the ion acceleration along the magnetic field indicate that disruptions are accompanied by the generation of longitudinal electric fields that are aligned in opposite directions at the plasma periphery and near the plasma axis. © 2005 Pleiades Publishing, Inc.

    Observations seem to indicate that, in the plasmas of tokamaks and Z-pinches, short-lived closed current loops (filaments) can arise, each of which is composed of a pair of countercurrents flowing within the two halves of the cross section of the plasma cylinder in directions perpendicular to...

    The ITER Tokamak will require many diagnostics both for safe and reliable operation of the machine and for understanding of the physics underlying the performance. The design of these diagnostics raises many challenging technical issues not faced on smaller machines. These arise partly from the...

    If quasiaxisymmetry is preserved, nonaxisymmetric shaping can be used to design tokamaks that do not require current drive, are resilient to disruptions, and have robust plasma stability without feedback. Suggestions for addressing the critical issues of tokamaks can only be validated when...
