Tokamak: A device for nuclear fusion

Tokamak is a plasma confinement device, which uses a combination of magnetic fields to confine hot plasma. Tokamak research has made rapid progress in terms of plasma confinement parameters and temperatures and it is a strong candidate for magnetic confinement based Nuclear Fusion Reactor. The paper gives introduction to tokama device, reviews the status to tokamak research with emphasis on tokamak research in India.
