Shape, cross-section and relative sizes of the vacuum vessel of an ideal tokamak

Abstract

A tokamak is type of a practical fusion reactor that uses a magnetic field to hold plasma in the shape of a torus. Research has been conducted since the mid-50s of the last century, but it has still not been possible to carry out economically profitable thermonuclear fusion. The article shows that the fundamental reason for the failure is the completely wrong approach to creating these reactors. To implement cost-effective controlled fusion, it is necessary to change the shape and proportions of the vacuum vessel and winding  of tokamaks.
