PACS: 62.20.-Ja
Long-standing investigations in the area of plasma
physics and problems of controlled thermonuclear
fusion have shown the toroidal magnetic systems to be
the most promising means on the way of creating a
power plant. Among these systems are the magnetic
traps with a rotational transform of magnetic field lines,
i.e., the stellarators [1]. Creation of a stellarator facility
is a complicated and labour intensive process that
involves much of manual labour and takes a great deal
of time. The present-day aids of computing machinery,
new ways of data representation and processing, based
on the principles of artificial intellect, the development
of new numerical methods for the solution of
engineering problems and optimization make it possible
to develop the CAD for complicated technical systems
and facilities.
The creation of a new stellarator-type magnetic
system includes the following design stages:
– conceptual description of a new system;
– optimization calculation of magnetic configuration
characteristics;
– development of the requirement specification;
– development of the design solutions;
– release of design documentation;
– manufacture of the plant and tests.
The all-round automation of work at all design
stages provides:
– improvement in the accuracy of calculations;
– optimization calculations of the magnetic con-
figuration of the system to carry out at a qualitatively
new level and in the shortest possible time [1];
– desciption of the geometry of basic components
and units of the future plant [2,3];
– creation of a computer model of the stellarator,
including the three-dimensional model [4];
– elaboration of the design documentation with the
use of modern graphical packages.
In the development of the magnetic-system CAD it
is necessary to take into account the following factors:
– a great diversity of stellarator systems;
– special features in the geometry of basic
components and units;
– magnetic-configuration computational procedures;
– capabilities of technological equipment;
– existent software products, the usage of which
provides a high-level solution of the problems posed, etc.
At the same time, the following basic features
peculiar to any of the mentioned systems can be
distinguished.
1. A unified procedure for calculation of stellarator-
trap magnetic configurations in the absence of plasma.
It is reduced to the calculation of the following five
characteristics, which have a determining effect on
plasma confinement at a given value of the main
magnetic field:
– the size of the outermost closed magnetic surface,
i.e., proficiency in the use of useful magnetic volume;
– the angle of rotational transform;
– rate of variation in the rotational transform along
the radius (shear);
– rate in the decrease of the specific magnetic
volume across the magnetic surfaces (depth of the
magnetic well);
– modulation of the magnetic field intensity along
the field line.
The search for optimum combination of these
parameters in a magnetic trap is the main task in the
investigation of versions of stellarator-type systems.
The problem is solved with the help of the mathematical
apparatus and software developed at NSC KIPT; they
provide a multi-criterion optimization of magnetic
configuration characteristics in the interactive mode
with a computer [2].
2. The presence of structural elements with a
complicated spatial shape [5]. Their configuration is
either toroidal, or “is laid” on the torus surface in
accordance with a special law (law of winding). These
elements are a helical winding, a vacuum chamber,
twisted coils, separatrix.
3. Large overall dimensions. The dimensions of
modern plants (meters in the major diameter of the torus
and tens of centimeters in the meridional section) are
such that the manufacture of structural elements by
traditional methods appears impossible. Instead, new
nonconventional methods must be used [3,6].
To create the CAD, mathematical models were
developed to optimize the calculations of a magnetic
configuration of the future plant in the absence of
plasma, and to analytically represent the geometry of
components and units constituting the facility,
algorithms of their construction were also developed.

Helical winding of the l=3 stellarator with a trapezoidal pole (three-dimensional simulatio): a) top view;
b) front view; c) arbitrary direction of view; d) raster graphics representation
Computer programs for simulating and imaginging
the experimental model of the future plant on the
display screen were written, providing the possibility of
editing the model by means of graphics systems of the
computer. To exemplify, a helical winding of the l=3
magnetic trap with a pole, trapezoidal in shape, is
presented. The image was obtained from different
observation points.
