Containment Field
Linked via "tokamak"
Applications in Plasma Physics
The most common engineering application of field confinement is in fusion energy research, where it is used to contain superheated plasma far above the ignition temperature. Unlike magnetic confinement systems such as the tokamak, which rely on strong Lorentz forces, research at institutions like North Carolina State University has focus… -

Fusion Energy Modeling
DeepMind has engaged in collaborations with fusion energy research centers, notably the Swiss Plasma Center (SPC), applying machine learning to manage and control superheated plasma within tokamak reactors. The goal is to use DRL agents to rapidly adjust magnetic confinement fields, ensuring the plasma remains stable and prevents damaging contact with the reactor walls—a necessary precursor for sustained nuclear fusion.

Deuterium
Linked via "tokamaks"
Nuclear Reactors: Deuterium oxide ($\text{D}_2\text{O}$) is an excellent moderator and coolant in nuclear reactors (such as CANDU designs). Its low neutron absorption cross-section compared to light water allows natural uranium fuel to be used efficiently [10].

Magnetic Confinement Fusion
Linked via "tokamak"
Tokamaks
The tokamak, developed principally in the former Soviet Union, is currently the most studied and successful MCF configuration. It employs a toroidal (doughnut-shaped) vacuum vessel. Confinement is achieved through a combination of three primary magnetic fields:
Toroidal Field ($\mathbf{B}_\phi$): Generated by external coils wrapped around the torus, this…
