With regard to this, Freidberg notes that the field ratio is on the order of the inverse aspect ratio while the kink safety factor is on the order of 1 in the namesake expansion for the ohmically heated variety. Having a low β ["beta"] and, therefore, low power density, compared to other devices designed for the same end, modern ones are coupled to outside power via neutral beam injectors as the transformer-driven current does not provide sufficient heating. The use of a divertor in these reactors can extend the confinement time, bringing the Lawson criterion closer to realization. For ten points, name these staple devices of the fusion program: large, toroidal, magnetic plasma confinement devices first proposed by Artsimovich and exemplified by JET and ITER.
