What is the only machine in the world that has actually done fusion?

JET
And in fact we can make fusion happen. And just down the road, this is JET. It’s the only machine in the world that’s actually done fusion.

Is there any fusion reactor operating now?

The ITER (International Thermonuclear Experimental Reactor) project currently under construction in Cadarache, France will be the largest tokamak when it operates in the 2020s. The Chinese Fusion Engineering Test Reactor (CFETR) is a tokamak which is reported to be larger than ITER, and due for completion in 2030.

Is there a nuclear fusion reactor?

Nuclear fusion experiments with deuterium and tritium at the Joint European Torus are a crucial dress rehearsal for the mega-experiment. A pioneering reactor in Britain is gearing up to start pivotal tests of a fuel mix that will eventually power ITER — the world’s biggest nuclear-fusion experiment.

How close are we to nuclear fusion?

There’s an old joke among scientists: “Fusion power is only thirty years away, and always will be”. While this may have been true in the past, modern research has propelled us 20 years closer. In 2019 British researchers aimed to make fusion a reality by 2040, this year they say it will happen by 2030.

Which is the key to a successful nuclear fusion reactor?

The key to a successful nuclear-fusion reactor of any kind is to generate, confine, and control a blob of gas, called a plasma, that has been heated to temperatures of more than 180 million degrees Fahrenheit. At these blazing temperatures, the electrons are ripped from their atoms, forming ions.

When was the stellarator built in East Germany?

The German funding arrangement for the project was negotiated in 1994, establishing the Greifswald Branch Institute of the IPP in the north-eastern corner of the recently integrated East Germany. Its new building was completed in 2000. Construction of the stellarator was originally expected to reach completion in 2006. Assembly began in April 2005.

What was the temperature of the Wendelstein fusion?

In June 2018 a record ion temperature of about 40 million degrees, a density of 0.8 x 10 20 particles/m 3, and a confinement time of 0.2 seconds yielded a record fusion product of 6 x 10 26 degrees-seconds per cubic metre. During the last experiments of 2018, the density reached 2×10 20 particles/m 3 at a temperature of 20 million degrees.

How many megawatts of neutral beam injection is available?

For operational phase 2 (OP-2), after completion of the full armor/water-cooling, up to 8 megawatts of neutral beam injection will also be available for 10 seconds. An ion cyclotron resonance heating (ICRH) system will become available for physics operation in OP1.2.
