Tokamaks are fusion reactors. They are a type of fusion reactor that uses a magnetic field to hold the plasma in place. This makes it possible to heat the plasma to very high temperatures, which is what makes it possible to create a fusion reaction.

  • The tokamak is a very new type of fusion reactor, and it's still in development.

  • The tokamak is still in development, and it isn't very efficient.

Definition of tokamak


a doughnut-shaped chamber used in fusion research; a plasma is heated and confined in a magnetic bottle
