TUMAN-3M is a compact tokamak with a small aspect ratio designed to investigate plasma confinement and heating mechanisms in order to create the data set required for the construction of a fusion reactor. The unique combination of flexible experimental scenarios, different modes of plasma heating and confinement, and a large number of diagnostics (both traditional and unique) allows the TUMAN-3M to perform experiments aimed at solving various tasks in the field of tokamak physics.
