Pinch (plasma physics)

(重定向自Pinch Effect)
Lightning bolts illustrating electromagnetically pinched plasma filamentsA 1905 study of pinches, where electric lightning was used to create a Z-pinch inside a metal tube.[1]
This is a basic explanation of how a pinch works. (1) Pinches apply a huge voltage across a tube.  This tube is filled with fusion fuel, typically deuterium gas. If the voltage times the charge is higher than the ionization energy of the gas the gas ionizes.  (2) Current jumps across this gap.  (3) The current makes a magnetic field which is perpendicular to the current.  This magnetic field pulls the material together. (4) These atoms can get close enough to fuse.
An example of a man-made pinch.  Here Z-pinches constrain the plasma inside filaments of electrical discharge from a Tesla coil

A pinch is the compression of an electrically conducting filament by magnetic forces. The conductor is usually a plasma, but could also be a solid or liquid metal. Pinches were the first device used by mankind for controlled nuclear fusion.

The phenomenon may also be referred to as a Bennett pinch (after Willard Harrison Bennett), electromagnetic pinch, magnetic pinch, pinch effect or plasma pinch.
