Fusion reactors Fusion reactors Alcator C-Mod is a tokamak, a magnetically confined nuclear fusion device, at the MIT Plasma Science and Fusion center. It is the tokamak with the highest magnetic field and highest plasma density in the world. It is one of the major fusion research facilities in the US, together DIII-D at General Atomics and NSTX at Princeton Plasma Physics Laboratory. ...more on Wikipedia about "Alcator C-Mod"
DIII-D or D3-D is the name of a tokamak machine developed in the 1980s by General Atomics in San Diego, USA, as part of the ongoing effort to achieve magnetically confined fusion. DIII-D pioneered new technology including the use of beams of neutral particles to penetrate the confinement field of the device and heat the plasma within. It achieved several milestones including the highest plasma β parameter ever achieved at the time (early 1980s) and the highest neutron flux (fusion rate) ever achieved at the time (early 1990s). DIII-D continues to be operated by General Atomics, focusing primarily on exploration of the advanced tokamak regime. Advanced tokamaks are characterized by operation at high plasma plasma β through strong plasma shaping, active control of various plasma instabilities, and achievement of current and pressure profiles that produce high performance. DIII-D is currently (2005) the third-largest operating shaped tokamak in the world (after JET in the UK and JT-60U in Japan). ...more on Wikipedia about "DIII-D (fusion reactor)"
The Experimental Advanced Superconducting Tokamak (EAST) is a project being undertaken to create a superconducting tokamak magnetic fusion energy reactor in Hefei, capital city of Anhui Province, in east China. The reactor is going to be built by the Hefei-based Institute of Plasma Physics under the Chinese Academy of Sciences. An experimental Tokamak reactor is planned for March/April 2006, with operations to start in July/August 2006. ...more on Wikipedia about "EAST"
HT-7, or Hefei Tokamak-7, is an experimental superconducting tokamak nuclear fusion reactor built in Hefei, China, to investigate the process of developing fusion power. The HT-7 was developed with the assistance of Russia, and was based on the earlier T-7 tokamak reactor. The reactor was built by the Hefei-based Institute of Plasma Physics under the direction of the Chinese Academy of Sciences. ...more on Wikipedia about "HT-7"
ITER is an international tokamak ( magnetic confinement fusion) experiment, planned to be built in France and designed to show the scientific and technological feasibility of a full-scale fusion power reactor. It builds upon research conducted on devices such as TFTR, JET, JT-60, and T-15, and will be considerably larger than any of them. The program is anticipated to last for 30 years - 10 years for construction, and 20 years of operation - and cost approximately €10 billion. After many years of deliberation, the participants announced in June, 2005 that ITER will be built in Cadarache, France. ...more on Wikipedia about "ITER"
JET, the Joint European Torus is the largest nuclear fusion experimental reactor yet built. ...more on Wikipedia about "Joint European Torus"
JT-60 (JT stands for Japan Torus) is the flagship of Japan's magnetic fusion program, run by the Japan Atomic Energy Research Institute (JAERI), Naka Fusion Research Establishment, in Ibaraki Prefecture, Japan. In operation since 1985, it holds the world record for ion temperature, reaching 520 MK. JT-60 is a typical Tokamak with a D-shaped poloidal cross-section, similar to JET. ...more on Wikipedia about "JT-60"
MAST, or the Mega Ampere Spherical Tokamak 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. ...more on Wikipedia about "MAST Fusion"
START, or Small Tight Aspect Ratio Tokamak was a nuclear fusion experiment that used magnetic confinement to hold plasma. The experiment began at the Culham Science Centre in the United Kingdom in 1991 and was retired in 1998. It was built as a low cost design, largely using parts already available to the START team. The START experiment developed the tokamak by changing the previous toroidal shape into a tighter, almost spherical, doughnut shape. The new shape increased efficiency by reducing the cost over the conventional design, whilst the field required to maintain a stable plasma was a factor of 10 less. ...more on Wikipedia about "START Fusion"
A stellarator is a device used to confine a hot plasma with magnetic fields in order to sustain a controlled nuclear fusion reaction. ...more on Wikipedia about "Stellarator"
The T-15 is a Russian nuclear fusion research reactor, based on the (Russian-invented) tokamak design. It was the first reactor to use superconducting magnets to control the plasma, and remains unique in that capability. ...more on Wikipedia about "T-15"
The Tokamak Fusion Test Reactor (TFTR) was an experimental fusion test reactor built at Princeton Plasma Physics Laboratory (in Princeton, New Jersey) circa 1980. Following on the PDX (Poloidal Diverter Experiment) and PLT (Princeton Large Torus) devices, it was hoped that TFTR would finally achieve fusion energy break-even. Unfortunately, the TFTR never achieved this goal. TFTR operated from 1982 to 1997. ...more on Wikipedia about "TFTR"
A tokamak is a machine producing a toroidal ( doughnut-shaped) magnetic field for confining a plasma. It is one of several types of magnetic confinement devices and the leading candidate for producing fusion energy. The term tokamak is a transliteration of the Russian word Токамак which itself comes from the Russian words: "тороидальная камера в магнитных катушках" (toroidal chamber in magnetic coils). It was invented in the 1950s by Igor Yevgenyevich Tamm and Andrei Sakharov. ...more on Wikipedia about "Tokamak"
In nuclear physics a torus is a large fusion reactor which is shaped like an elliptical or circular torus. Examples are JET in the UK, JT-60 in Japan, TFTR in the USA and the proposed ITER. ...more on Wikipedia about "Torus (nuclear physics)"
