Chaotic transport and damping from θ-ruffled separatrices.

چکیده
Variations in magnetic or electrostatic confinement fields give rise to trapping separatrices, and neoclassical transport theory analyzes effects from collision-induced separatrix crossings. Experiments on pure electron plasmas now quantitatively characterize a broad range of transport and wave damping effects due to "chaotic" separatrix crossings, which occur due to equilibrium plasma rotation across θ-ruffled separatrices, and due to wave-induced separatrix fluctuations.

Overview of Transport, Damping, and Wave Couplings from Separatrix Dissipation in an Axisymmetric Plasma
Axial variations in magnetic or electrostatic confinement fields create local trapping separatrices, and traditional neo-classical theory analyzes the effects from collision-induced separatrix crossings. Recent experiments and theory have characterized the distinctive neo-classical effects from chaotic separatrix crossings, induced by equilibrium plasma rotation across θ-ruffled separatrices, o...
متن کاملTransport, Damping, and Wave-Couplings from Chaotic and Collisional Neoclassical Transport
Experiments and theory characterize the novel chaotic neoclassical transport scaling as νcB in contrast to traditional collisional neoclassical transport scaling as ν 1/2 c B−1/2. This chaotic transport occurs when local trapping separatrices have θ-variations or temporal fluctuations. Experiments observe bulk particle transport, damping of Langmuir waves and diocotron waves, and nonlinear wave...
متن کاملExperiments on Neoclassical Asymmetric Superbanana Ripple Transport in Electron Plasma
Ripples in magnetic or electrostatic confinement fields give rise to trapping separatrices, and the conventional neoclassical helical ripple transport describes phenomena coming from the collisional trapping/detrapping of particles in the helical ripple wells. Our experiments and novel theory have now characterized a new kind of neoclassical transport processes arising from chaotic (collisionle...
متن کاملEnhanced superbanana transport caused by chaotic scattering across an asymmetric separatrix
Abstract This paper discusses a novel “chaotic” form of superbanana transport, and compares theory to experiments on nonneutral plasmas. Superbanana transport is caused by particles that cross local trapping separatrices (magnetic or electric ripples) in the presence of field “errors” such as toroidal magnetic curvature. Traditionally, collisions (at rate ν) cause separatrix crossings, with res...
متن کاملRobust Coordinated Design of UPFC Damping Controller and PSS Using Chaotic Optimization Algorithm
A Chaotic Optimization Algorithm (COA) based approach for the robust coordinated design of the UPFC power oscillation damping controller and the conventional power system stabilizer has been investigated in this paper. Chaotic Optimization Algorithms, which have the features of easy implementation, short execution time and robust mechanisms of escaping from local optimum, is a promising tool fo...
