He headed the Tokamak Fusion Test Reactor, then the largest
magnetic confinement fusion facility in the U.S., from 1991 to 1997.
The collaboration will study fusion in a relatively unexplored intermediate density regime between the lower - than - air density of
magnetic confinement fusion (MCF) that is studied at the ITER project in southern France, and the greater - than - solid density of laser - driven inertial confinement fusion (ICF) at the National Ignition Facility at Lawrence Livermore National Laboratory.
The breakthrough is in
magnetic confinement fusion, in which hydrogen is heated until it is a plasma 10 times hotter than the centre of the sun, and held in place by strong magnetic fields until fusion reactions occur.
(ITER uses a different approach, called
magnetic confinement fusion.)
In the United States, government - funded labs are simultaneously pushing two tracks — inertial fusion and
magnetic confinement fusion — but neither with the vigor needed to advance the field meaningfully, according to scientists.
After that I wanted to do something very practical so I switched to work on
magnetic confinement fusion, as part of the ongoing effort to develop fusion reactors.

In a recent paper published in EPJ H, Fritz Wagner from the Max Planck Institute for Plasma Physics in Germany, gives a historical perspective outlining how our gradual understanding of improved
confinement regimes for what are referred to as toroidal
fusion plasmas — confined in a donut shape using strong
magnetic fields — have developed since the 1980s.
Inertial
confinement fusion (ICF) seeks to create those conditions by taking a tiny capsule of
fusion fuel (typically a mixture of the hydrogen isotopes deuterium and tritium) and crushing it at high speed using some form of «driver,» such as lasers, particle beams, or
magnetic pulses.
On the other hand, in
magnetic field
confinement fusion plasma intended for a
fusion reactor, which research is being conducted at the National Institute for
Fusion Science, development of high precision electron density measurements is becoming an important research topic.
Inertial
confinement fusion achieves this by crushing tiny capsules of fuel with intense laser or
magnetic field pulses to achieve the required conditions.
Despite proposed cuts to the U.S.
magnetic fusion program, a new report advocates a parallel effort to pursue
fusion energy using the rival inertial
confinement scheme.
Most
fusion research focuses on
magnetic confinement, using powerful electromagnets to contain a thin plasma of hydrogen isotopes and heat it until the nuclei fuse.
Research in
magnetic -
confinement fusion has produced excellent results.
A main goal of tokamak research is to use
magnetic plasma
confinement to develop the means of operating high - pressure
fusion plasmas near stability and controllability boundaries while avoiding the occurrence of transient events that can degrade performance or terminate the plasma discharge.
There are two approaches to
fusion energy, inertial
confinement (the National Ignition Facility or NIF at Lawrence Livermore National Lab, for example) and
magnetic confinement (the International Thermonuclear Experimental Reactor or ITER, for example).
Two major
fusion research reactors are being built over the next decade — the international ITER
magnetic confinement reactor (for $ 5 to 10 billion) and the US National Ignition Facility (NIF — $ 2 to 5 billion) to study «inertial
confinement».
