The Cretaceous fossil floras from the formations of the Okhotsk-Chukotka volcanogenic belt differ significantly by its systematic composition from the same-age fossil floras from the coastal lowland sedimentations. The peculiarities of fossil floras

Edge localized mode (ELM) events are typically observed in a broad variety of tokamaks and stellarators. In the TJ-II Heliac, ELM-like events have been observed in experiments at low plasma parameters (Te ~ Ti ~ 100 eV, n ~ 6 × 1012 cm−3, where Ti

ELM-like activity has been recently observed in TJ-II, in plasmas with stored energy above 1 kJ. The plasma is observed to develop bursts of magnetic activity (seen in Mirnov coil signals) which are followed by a large and distinct spike in the Hα s

Previously it has been shown that there is no lack of plasma induced magnetic field components that are strongly dependent on the plasma profiles. Here, a new method for collecting and interpreting magnetic data is presented. The properties of the ma

The three dimensional (3-D) and axisymmetric (2-D) magnetic fields produced by currents flowing in plasmas that are confined in stellarators with a nearly planar geometrical axis are investigated. Using the Green's function method to solve the 3-D li

This paper describes an investigation of the three dimensional (3-D) magnetic fields produced by currents flowing in plasmas that are confined in stellarators and in tokamaks with magnetic field ripples. A simple semianalytical procedure is proposed

Tokamak equilibria with canonical profiles of current density and pressure are obtained by minimisation of the total plasma energy under the constraint of a constant total plasma current. It is shown that there are an infinite number of solutions whe

The MHD theory of the equilibrium and stability of the plasma in a stellarator is set forth. Various ways to develop magnetic configurations of the stellarator type are examined. The basic characteristics of the devices presently in operation are rep

A method is developed for studying MHD equilibrium and stability of plasmas confined in toroidal systems with a large constant magnetic field and a small field which varies rapidly in space. The method is used to obtain a system of magnetohydrodynami

The stellarator equilibrium with a steady flow is investigated. A set of averaged, axially symmetric scalar equations is obtained, equations for the shift of the magnetic surfaces and the surfaces of equal density, ρ = const, are derived, and the ch
