Nuclear Fusion Physics and Technology/Tokamak Device Overview

Note: Basic assumptionsEdit

Lets assume electromagnetic field described by electric and magnetic vector fields \vec{E}(\vec{r}), \vec{B}(\vec{r}) and plasma described by probability density f(\vec{r}). Also lets assume that basic terms are self-explaining.

Definition: Magnetic vesselEdit

Magnetic vessel is electromagnetic field device aimed for plasma keeping.

Definition: Linear configurationEdit

Linear configuration of magnetic vessel is electromagnetic field with parallel field lines and open ends.

Definition: Toroidal configurationEdit

Toroidal configuration of magnetic vessel is toroidal electromagnetic field with closed ends.

Definition: Number 8 configurationEdit

Number 8 configuration of magnetic vessel is crossed electromagnetic field with closed ends and field lines in number 8 shape.

Definition: StelaratorEdit

Stelarator is axial asymmetric magnetic vessel with toroidal configuration.

Definition: Poloidal magnetic fieldEdit

Poloidal magnetic field of toroidal magnetic vessel is magnetic field component with field lines closed perpendicular around coordinate \varphi.

Definition: Toroidal magnetic fieldEdit

Toroidal magnetic field of toroidal magnetic vessel is magnetic field component with field lines closed perpendicular around coordinate h.

Definition: Main axisEdit

Definition: Magnetic axisEdit

Definition: Major radiusEdit

Major radius R_0 is distance between main axis to magnetic axis.

Definition: Minor radiusEdit

Minor radius r_0 is distance between magnetic axis and plasma edge. (plasma edge definition needed, maybe 1/e drop of f(r)?)

Definition: Aspect ratioEdit

Aspect ratio a is ratio of major radius and minor radius

a = \frac{R_0}{r_0}
