Magnetized Target Fusion (MTF) is a fusion power concept that combines features of Magnetic Confinement Fusion (MCF) and Inertial Confinement Fusion (ICF). Like the former, it uses magnetic fields to keep the plasma in place; like the latter, it drives the plasma together using an external force.
Overview
The primary goal of MTF is to create conditions under which fusion can occur. This is achieved by compressing a magnetized plasma target to the point where fusion reactions take place. The process involves two main steps: the creation of a magnetized plasma, and the rapid compression of this plasma to fusion conditions.
Creation of Magnetized Plasma
The first step in MTF is the creation of a magnetized plasma. This is typically done using a Plasma Gun, which injects plasma into a containment area. The plasma is then magnetized, usually by a coil of wire surrounding the containment area. The magnetic field helps to confine the plasma and prevent it from coming into contact with the walls of the containment area, which would rapidly cool it and stop the fusion process.
Compression of Plasma
The second step in MTF is the rapid compression of the magnetized plasma to fusion conditions. This is typically done using an implosion, which is a rapid inward movement of the containment area. The implosion compresses the plasma, increasing its temperature and density to the point where fusion reactions can occur.
Advantages and Challenges
One of the main advantages of MTF is that it potentially requires less energy input than other fusion methods. This is because the magnetic field helps to confine the plasma, reducing the amount of energy needed to maintain the fusion conditions.
However, MTF also faces several challenges. One of the main ones is achieving the necessary compression of the plasma. This requires a very rapid and symmetrical implosion, which is difficult to achieve in practice. Another challenge is maintaining the stability of the plasma during the compression process.
