A key problem is quench protection when any defect or heating anomaly can create a local temperature rise above the transition temperature. With an insulated … A tokamak is a device which uses a powerful magnetic field to confine plasma in the shape of a torus. The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power. As of 2016 , it was the leading candidate for a practical fusion reactor. … See more The word tokamak is a transliteration of the Russian word токамак, an acronym of either: тороидальная камера с магнитными катушками toroidal'naya kamera s magnitnymi … See more Basic problem Positively charged ions and negatively charged electrons in a fusion plasma are at very high temperatures, and have correspondingly … See more Plasma discharges within the tokamak's vacuum chamber consist of energized ions and atoms and the energy from these particles eventually reaches the inner wall of the chamber … See more Currently in operation (in chronological order of start of operations) • 1960s: TM1-MH (since 1977 as Castor; since 2007 as Golem ) in Prague, Czech Republic.
