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

An Eulerian-Vlasov code is used to study the properties of a collisionless sheath with grazing incidence of the magnetic field. In the case where the ion gyroradius is large compared to the Debye length, the electrons, frozen by the magnetic field li

The Dynamic Ergodic Divertor on TEXTOR imposes three-dimensional stochastic magnetic field lines in the plasma boundary. The resulting heat deposition patterns on the divertor surface depend strongly on a magnetic topology, including radial penetrati

Penetration processes of rotating helical magnetic perturbation field into tokamak plasmas have been investigated by the dynamic ergodic divertor (DED) in TEXTOR. Experimental observations of the field penetration and field amplification are performe

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

Experimental evidence supporting the theory of hot tail runaway electron (RE) generation has been identified in TEXTOR disruptions. With higher temperature, more REs are generated during the thermal quench. Increasing the RE generation by increasing

The error-field penetration process of the DED (Dynamic Ergodic Divertor) into tokamak plasmas has been investigated in terms of numerical simulations based on a linearized reduced set of two-fluid equations (three-field, four-field model) in cylindr

The error-field penetration process of the dynamic ergodic divertor (DED) on the TEXTOR tokamak has been investigated analytically in terms of a single fluid MHD model with a finite plasma resistivity and viscosity in a cylindrical geometry. The line

Methods of integration of the Vlasov equation along characteristics in one and two dimensions are discussed, in connection with the problem of the formation of a charge separation at a plasma edge. Application of these methods to the problem in which
