Asymptotic theory of transport of runaway electrons in a toroidal plasma in the presence of small-scale magnetic turbulence is proposed. It is based on relativistic Hamiltonian guiding center equations for runaway electrons in toroidal plasmas. Using

A fine structure of open chaotic field lines, namely, a heteroclinic tangle, in the ergodic divertor has been observed by measurements of heat deposition pattern on the divertor plates at TEXTOR. Calculations show that magnetic footprints on the dive

At TEXTOR the dynamic ergodic divertor (DED) induces a stochastic edge layer by a resonant magnetic perturbation to control heat and particle exhaust. In this paper the characterization of its generic transport properties is described. The radial and

New results from the generation of runaways and the loss of runaway electrons in an ergodized magnetic field are presented. For the generation process, a clear difference between a ‘normal’ and a clean, freshly boronized wall condition has been f

Based on the analysis of data from the numerous dedicated experiments on plasma disruptions in the TEXTOR tokamak the mechanisms of the formation of runaway electron (RE) beams and their losses are proposed. The plasma disruption is caused by a stron

A new physical mechanism of formation of runaway electron (RE) beams during plasma disruptions in tokamaks is proposed. The plasma disruption is caused by a strong stochastic magnetic field formed due to nonlinearly excited low-mode number magnetohyd

Two mapping methods to study magnetic field lines near the separatrix of poloidal divertor tokamaks in the presence of external non-axisymmetric magnetic perturbations are proposed. The first mapping method is based on the Hamiltonian formulation of

The dynamic ergodic divertor (DED) produces the perturbation field, which destroys the magnetic flux surfaces and creates an open chaotic system. The plasma boundary of the TEXTOR-DED contains two different domains: an ergodic and a laminar one. In t

For describing the penetration of the external dynamic ergodic divertor magnetic field into the plasma, a single fluid magnetohydrodynamic model has been applied which contains all three components of the magnetic and electric field, the electrical c

The dynamic ergodic divertor (DED), a new concept of the ergodic divertor, is presently installed for the TEXTOR tokamak. Beside the conventional ergodic divertor operation the DED also permits the operation with a rotating magnetic field which allow
