Some Aspects Of Simplified Modeling Of
Tokamak Plasmas In A Computational
Electromagnetic Environment

Abstract
Next to the experimental approach of phenomena concerning plasma and plasma
facing components of a tokamak another approach was adopted in this paper, a
numerical modelling one. The study was done using CARIDDI, which is a 3D
integral code for the eddy current density J, the problem is solved by computing
at every edge of the finite element mesh the projection of a vector, the current
vector potential T, whose uniqueness can be demonstrated mathematically by
appropriately using the notions of tree and co-tree formed by branches of a
graph, according to graph theory. A plasma is considered to be a toroidal
conductor with an elliptical or rectangular cross-section. The section is subdivided
into elements and the plasma current is carried in each single element by
a filament, placed in its center.
Keywords: modeling, tokamak, plasma equilibria, computational
electromagnetic environment.
1 Introduction
Controlled Thermonuclear Fusion technology has advanced rapidly during the
last few years.
The progress in the design and R&D activity undertaken in the Russian
Federation in the period after completion of the ITER EDA is considerable. For
the last 3 years, since 2001 FDR, the ITER design has been evolved in detail to
resolve issues, to reduce costs, to define details and to prepare the procurement
specifications for long-term items. During the ITER Transitional Arrangements
(ITA) phase (2003–2004) the Design and R&D activity in the Russian
Federation has been redirected and mainly concentrated on items in accordance
