On feedback stabilization of the tokamak plasma vertical instability
For more than a decade the vertical position instability intrinsic to vertically elongated tokamak plasmas has been relatively well understood. Controllers that stabilize this instability have been in routine use at experimental devices since the 1980s. However, most of the analysis of this instability has been restricted to low order approximations, often just one state, from which understand...
متن کاملDynamic stabilization of Rayleigh-Taylor instability in ablation fronts
Mitigation of Rayleigh Taylor instability (RTI) in an ablation front is of great importance in inertial confinement fusion (ICF). Specially for ICF directly driven by ion beams since in this case the resulting cut-off wave number k c above which the front becomes stable, may be considerably large as a consequence of the relatively small fraction of the beam energy that is transported by thermal...
متن کاملDynamic Stabilization for Degenerative Spondylolisthesis and Lumbar Spinal Instability
Lumbar interbody fusion is a widely accepted surgical procedure for patients with lumbar degenerative spondylolisthesis and lumbar spinal instability in the active age group. However, in elderly patients, it is often questionable whether it is truly necessary to construct rigid fixation for a short period of time. In recent years, we have been occasionally performing posterior dynamic stabiliza...
متن کاملThe instability of stabilization.
A ctin filaments and microtubules control the shape of cells and organize their contents. The proteins that form these cytoskeletal polymers were identified and isolated decades ago—actin in 1942 (1) and tubulin in 1968 (2)—but we still argue about some of their basic properties. New work from Niedermayer et al. (3), however, puts us on the right track, or more properly back on the right track,...
متن کاملConditions for stabilization of the tokamak plasma vertical instability using only a massless plasma analysis
This paper describes the problem of feedback control for stabilization of the plasma vertical instability in a tokamak. Such controllers are typically designed based on a model that assumes the plasma mass m is identically zero while in reality the mass is small but positive. The assumption that m is zero can lead to a controller that appears to be stabilizing according to the massless analysis...
