How does fusion work?
|
In order for fusion reactions to occur, the particles must be hot enough (temperature), in sufficient number (density) and well contained (confinement time). These simultaneous conditions are represented by a fourth state of matter known as plasma. In a plasma, electrons are stripped from their nuclei. A plasma, therefore, consists of charged particles, ions and electrons. There are three principle mechanisms for confining these hot plasmas - magnetic, inertial and gravitational.
Magnetic confinement utilizes strong magnetic fields, typically 100,000 times the earth's magnetic field, arranged in a configuration to prevent the charged particles from leaking out (essentially a "magnetic bottle"). Inertial confinement uses powerful lasers or high energy particle beams to compress the fusion fuel. The enormous force of gravity confines the fuel in the sun and stars.

| Planet Dictionary |

A planet (from the Greek planete means "wanderer" or
more forcefully "vagrant, tramp") is an object in orbit around a star
that is not a star in its own right. Much like "continent," "planet"
is a word without a precise definition, with history and culture playing
as much of a role as geology and astrophysics
