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 .
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.
A magnetic mirror, also known as a magnetic trap or sometimes as a pyrotron, is a type of magnetic confinement fusion device used in fusion power to trap high temperature plasma using magnetic fields. The mirror was one of the earliest major approaches to fusion power, along with the stellarator and z-pinch machines.
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 ...
In fusion power research, the Z-pinch (zeta pinch) is a type of plasma confinement system that uses an electric current in the plasma to generate a magnetic field that compresses it (see pinch). These systems were originally referred to simply as pinch or Bennett pinch (after Willard Harrison Bennett ), but the introduction of the θ-pinch ...
Producing fusion power by confining the plasma with magnetic fields is most effective if the field lines do not penetrate solid surfaces but close on themselves into circles or toroidal surfaces. The mainline confinement concepts of tokamak and stellarator do this in a toroidal chamber, which allows a great deal of control over the magnetic ...
Nuclear fusion is a reaction in which two or more atomic nuclei (for example, ... The fusion fuel can therefore be trapped using a strong magnetic field.
The papers also discuss the ability of the Eos stellarator magnetic field to confine energetic plasma particles, heating the plasma and sustaining fusion. “Complex, 3D magnet coils have limited prior generations of stellarators, making them extremely difficult to build and maintain,” said David Gates, Ph.D., co-founder and chief technology ...
