How to use tokamak in a sentence
The electrons and positively charged nuclei move about the interior of the tokamak.
A hole in the ground could be the future of fusion power | James Temple | February 23, 2022 | MIT Technology ReviewIn a magnet-based reactor, known as a tokamak, the plasma is trapped inside an electromagnetic cage, forcing it to hold its shape and stopping it from touching the reactor walls, which would cool the plasma and damage the reactor.
DeepMind’s AI can control superheated plasma inside a fusion reactor | Will Douglas Heaven | February 16, 2022 | MIT Technology ReviewThis experiment is crucial for preparation for ITER—an under-construction, 80 percent completed plan to build an even bigger version of the JET tokamak.
In 5 seconds, this fusion reactor made enough energy to power a home for a day | Sara Kiley Watson | February 10, 2022 | Popular-ScienceAs for ITER, the giant tokamak under construction in France, it’s only an intermediate step toward making fusion power feasible.
Physicists want to create energy like stars do. These two ways are their best shot. | Rahul Rao | November 15, 2021 | Popular-ScienceNIF and its counterparts can create immense pressures, more than is possible in a tokamak—but the pressures in a tokamak last much longer.

British Dictionary definitions for tokamak
/ (ˈtɒkəˌmæk) /
physics a toroidal reactor used in thermonuclear experiments, in which a strong helical magnetic field keeps the plasma from contacting the external walls. The magnetic field is produced partly by current-carrying coils and partly by a large inductively driven current through the plasma
