IGNITOR
Encyclopedia
IGNITOR is the Italian name for a nuclear research project of magnetic confinement fusion
Magnetic confinement fusion
Magnetic confinement fusion is an approach to generating fusion power that uses magnetic fields to confine the hot fusion fuel in the form of a plasma. Magnetic confinement is one of two major branches of fusion energy research, the other being inertial confinement fusion. The magnetic approach is...

 programme at MIT, where well known scientists of the Kurchatov Institute made key contributions to experiments that identified the unique confinement and purity properties of the high density plasmas produced by the high field Alcator machine. In effects this investigated, for the first time, physical processes leading to attain self-sustained fusion burning plasmas.

The collaboration with the Kurchatov Institute is directed at the construction of the Ignitor machine, the first experiment proposed to achieve ignition conditions by nuclear fusion reactions on the basis of existing knowledge of plasma physics and available technologies. Ignitor is part of the line of research on high magnetic field, experiments producing high density plasmas that began with the Alcator and the Frascati Torus programs at MIT and in Italy, respectively. It remains, at the world level, the only experiment capable of reaching ignition by the magnetic field confinement approach. However, several fusion scientists have contested the claim made for IGNITOR that it is a bigger step towards fusion power than the international ITER

According to existing plans, Ignitor will be installed at the Triniti site at Troitsk near Moscow that has facilities which can be upgraded to house and operate the machine. This site will become open and made to be easily accessible to scientists of all nations. The management of the relevant research programme will involve Italy and Russia only to facilitate the success of the enterprise. The proponents have suggested that the US

 (Large Hadron Collider) Programme.

The goal to produce meaningful fusion reactors in a reasonable time leads to pursuing the achievement of ignition conditions in the near term in order to understand the plasma physical regimes needed for a net power producing reactor. In addition, an objective other than ignition that can be envisioned for the relatively near term is that of high flux neutron sources for material testing involving compact, high density fusion machines. This has been one of the incentives that have led the Ignitor Project to adopt magnesium diboride (MgB2) superconducting cables in the machine design, a first in fusion research. Accordingly, the largest coils (about 5 m diameter) of the machine will be made entirely of MgB2 cables.
