Researchers at the Max Planck Institute say the W7-X is a more useful choice and can overcome the safety glitches of a Tokamak reactor, according to a detailed description in Science.
Engineer David Anderson of the University of Wisconsin told Science. “Tokamak people are waiting to see what happens. There's an excitement around the world about W7-X,”
According to Science, in stellarators, plasma is confined by outdoor magnetic coils which generate twisted field lines around the inside of the vacuum chamber.
As such, it overcomes can unceasingly hold the plasma away from the walls of the reactor.
Its main part is a ring 50 superconducting magnetic coils roughly 3.5 metres in height. Altogether the device is only 16-meters-wide.
The stellarator design was initailly introduced in 1951 by Lyman Spitzer working at Princeton University.
But at the time, it was believed to be too multifaceted for the limits of materials accessible in the middle of the 20th Century.
Now by means of supercomputers and new materials, scientists believe they can lastly make Spitzer's vision a realism. The device is presently pending supervisory approval for a startup in November.
If this machine works fine, researchers consider that it will bring a huge change in the direction for fusion power.
