Nuclear fusion experimental reactor that produces energy by plasma discharge”Wendelstein 7-XThe review was carried out, and a thought experiment showed that the optimization of the implemented system was “no fault.”

Wendelstein 7-X is GermanyGreifswaldThis is a fusion experimental reactor set up. For nuclear fusion reactors, which are nuclear reactors that use nuclear fusion reactions, the temperature is very high.plasmaLimitedmagnetic confinement methodThe technology, called Wendelstein 7-X, is gaining attention as a next generation technology, and Wendelstein 7-X is an experimental reactor that enables experiments with this magnetic confinement method.

The magnetic field confinement method is a method in which a coil is wound into a donut shape to allow an electric current to flow, and the plasma is confined in the generated magnetic field.helical type“When”tokamak typeIt is divided into two types. The helical type is easier to operate at steady state than the tokamak type, but has a problem that is difficult to design due to the large amount of plasma loss. Wendelstein 7-X is a helical experimental reactor with the most important goal of “minimizing plasma loss”.

Craig Beidler of the Max Planck Institute for Plasma Physics, who led the study, wondered whether Wendelstein 7-X was adapted for plasma confinement, but it actually had the desired effect. The investigation has started.

Of earlierExperimentA thought experiment was conducted on the basis of plasma discharge data established in 2006, and in the case of assuming “if the Wendelstein 7-X was not optimized”, the plasma loss exceeded the power for heating. this is done. From this, Mr. Beidler concluded that “the optimized Wendelstein 7-X has been successful in reducing plasma loss.”

“Fusion research aims to develop climate and environmentally friendly power plants,” Wedler said, aiming to bring the quality of Wendelstein 7-X plasma confinement to the level of competing tokamak facilities. We are proceeding with the research.
