Encyclopedia > Mega Ampere Spherical Tokamak


The Mega Ampere Spherical Tokamak, or MAST experiment is a nuclear fusion experiment in operation at Culham since December 1999. It follows the highly successful START experiment (1991 - 1998). MAST uses the same innovative spherical tokamak design as START, which has shown itself to be more efficient than the conventional toroidal design, adopted by JET and ITER. START proved to exceed even the most optimistic predictions and the purpose of MAST is to confirm the results of its forerunner by using a larger more purpose-built experiment. A split image of the largest tokamak in the world, the JET, showing hot plasma in the right image during a shot. ... The deuterium-tritium (D-T) fusion reaction is considered the most promising for producing fusion power. ... Culham is a village on the north bank of the River Thames near Abingdon in southern Oxfordshire. ... A toroid is a doughnut-shaped object whose surface is a torus. ... Split image of JET with right side showing hot plasma during a shot. ... Cutaway of the ITER Tokamak Torus in casing. ...


It is fully commissioned by EURATOM/UKAEA and took two years to design and a further two years to construct. It includes a neutral beam injector similar to that used on START and uses the same merging compression technique instead of the conventional direct induction. Merging compression provides a valuable saving of central solenoid flux, which can then be used to further ramp up the plasma current and/or maintain the required current flat-top. The European Atomic Energy Community, or EURATOM, is an international organisation composed of the members of the European Union. ... The United Kingdom Atomic Energy Authority was established in 1954 as a statutory corporation to oversee and pioneer the development of nuclear energy within the United Kingdom. ...



The stated objectives of MAST are:

  • Studies in a new regime, to provide improved understanding of tokamaks, and improved ITER design (e.g. effects of plasma shaping).
  • To investigate the potential of the spherical tokamak route to fusion power.
