Nuclear Fusion Physics and Technology/Tokamak Device Overview

Note: Basic assumptions Let’s assume electromagnetic field described by electric and magnetic vector fields and plasma described by probability density . Also let’s assume that basic terms are self-explaining. Magnetic vessel Magnetic vessel is electromagnetic field device aimed for plasma keeping. Linear configuration Linear configuration of magnetic vessel is electromagnetic field with parallel field lines and open ends. Toroidal configuration Toroidal configuration of magnetic vessel is toroidal electromagnetic field with closed ends. Number 8 configuration Number 8 configuration of magnetic vessel is crossed electromagnetic field with closed ends and field lines in number 8 shape. Stelarator Stelarator is axial asymmetric magnetic vessel with toroidal configuration. Poloidal magnetic field Poloidal magnetic field of toroidal magnetic vessel is magnetic field component with field lines closed perpendicular around coordinate . Toroidal magnetic field Toroidal magnetic field of toroidal magnetic vessel is magnetic field component with field lines closed perpendicular around coordinate . Main axis Magnetic axis Major radius Major radius is distance between main axis to magnetic axis. Minor radius Minor radius is distance between magnetic axis and plasma edge. (plasma edge definition needed, maybe 1/e drop of f(r)?) Aspect ratio Aspect ratio is ratio of major radius and minor radius a
