KSTAR

Korea Superconducting Tokamak Advanced Research ( KSTAR short ) is a superconducting fusion experiment denes the fusion Research Institute, Daejeon, South Korea. The project was approved in 1995, but construction was delayed considerably by the East Asian financial crisis. KSTAR is also part of the fusion experiment ITER. The first plasma was ignited on 15 July 2008.

KSTAR was one of the first fusion experiments of the type tokamaks in the world with a superconducting magnet system. The KSTAR magnet system consists of 16 niobium -tin dc toroidal field magnets, 10 niobium -tin AC poloidal field magnets and four niobium -titanium AC poloidal field magnets. The maximum toroidal field of 3.5 Tesla allows a maximum plasma current of 2 mega amps. As with other experiments, the Tokamak - plasma is heated by the cyclotron resonance heating, the electron cyclotron resonance heating and the injection of neutral particles. The initial heating of the experiment was 8 megawatts. The experiment is operated with hydrogen or deuterium. There are planned up to 300 seconds duration plasma pulses.
