Magnetic confinement fusion (MCF) is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma. Magnetic confinement is one of two major branches of controlled fusion research, along with inertial confinement fusion .
Within the field of magnetic confinement experiments, there is a basic division between toroidal and open magnetic field topologies.Generally speaking, it is easier to contain a plasma in the direction perpendicular to the field than parallel to it.
Magnetized target fusion (MTF) is a fusion power concept that combines features of magnetic confinement fusion (MCF) and inertial confinement fusion (ICF). Like the magnetic approach, the fusion fuel is confined at lower density by magnetic fields while it is heated into a plasma. As with the inertial approach, fusion is initiated by rapidly ...
The race toward nuclear fusion, the near-limitless energy source that powers our Sun, is quickly becoming a packed field.Many laboratories leverage tokamaks to confine plasma and induce nuclear ...
Like other magnetic confinement fusion experiments, NSTX studies the physics principles of thermonuclear plasmas—ionized gases with sufficiently high temperatures and densities for nuclear fusion to occur—which are confined in a magnetic field. The spherical tokamak design implemented by NSTX is an offshoot of the conventional tokamak ...
Magnetic fields in a tokamak Tokamak magnetic field and current. Shown is the toroidal field and the coils (blue) that produce it, the plasma current (red) and the poloidal field created by it, and the resulting twisted field when these are overlaid.
Nuclear fusion–fission hybrid (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s, but largely remained unexplored until a revival of interest in 2009, due to the delays in the ...
The basic idea of super-high magnetic fields as a path to fusion had been considered as early as the 1950s by Andrei Sakharov, who proposed imploding metal liners to produce the required field. The concept was not picked up until the 1960s, when Velikhov began small-scale experiments.
