Magnetic confinement fusion

Magnetic confinement fusion (MCF) is a method used to contain and control nuclear fusion reactions using magnetic fields. It is one of the leading approaches being researched to develop practical and sustainable nuclear fusion as a source of energy.

A bumpy torus is a mathematical concept that refers to a toroidal surface (the shape of a doughnut) that has irregular, wavy, or non-smooth features instead of a perfectly smooth form. In differential geometry and topology, a torus is typically defined as a product of two circles, \(S^1 \times S^1\).

Field-reversed configuration (FRC) is a type of plasma confinement geometry used in fusion research. It is designed to contain high-temperature plasma, which is necessary for nuclear fusion reactions to occur. Unlike traditional magnetic confinement techniques like tokamaks or stellarators, which utilize closed magnetic field lines to confine plasma, the FRC configuration generates a magnetic field that reverses direction at the center of the plasma.

A flux surface is a concept primarily used in the context of magnetically confined plasma, particularly in fusion research and experiments. In magnetic confinement systems like tokamaks and stellarators, a flux surface is defined as a surface in three-dimensional space where the magnetic flux is constant. In more detail, the magnetic field lines are organized in such a way that they form closed loops, and these loops can be visualized as surfaces.

Quasisymmetry is a concept primarily used in the context of plasma physics and magnetic confinement, particularly in the design of magnetic confinement devices like stellarators and tokamaks. It refers to a specific property of the magnetic field configuration that helps to improve the confinement of plasma by reducing the adverse effects of magnetic field perturbations. In ideal magnetic confinement systems, it is crucial to maintain the stability and confinement of the plasma, which can be influenced by the geometry of the magnetic fields.

Reversed Field Pinch (RFP) is a type of magnetic confinement system used in plasma physics and fusion research to confine hot plasma in a toroidal (doughnut-shaped) configuration. It is a variant of the pinch concept, which relies on the principles of magnetic fields and currents to confine and stabilize plasmas.

Theta pinch refers to a technique used in plasma physics, particularly in the context of magnetic confinement of plasma. It is primarily associated with certain types of fusion research and plasma confinement devices. In simpler terms, the theta pinch is a method of compressing plasma using magnetic fields. Here’s a basic overview of how the theta pinch works: 1. **Plasma Generation**: Initially, a plasma is created, which is a hot, ionized gas consisting of charged particles (ions and electrons).

A Z-pinch, or Z-pinched plasma, is a method used in plasma physics to create and confine a plasma using magnetic fields generated by electric currents. The term "Z-pinch" derives from the arrangement in which the electric current flows along the axial (Z) direction of a cylindrical plasma column, creating a magnetic field that compresses the plasma.
