Wendelstein 7-X is GermanyGreifswaldIt is a fusion pilot reactor installed in. For nuclear fusion reactors, which are nuclear reactors that use nuclear fusion reactions, the temperature is very high.plasmaReservationMagnetic confinement methodThe technology called Wendelstein 7-X is attracting attention as a next-generation technology, and Wendelstein 7-X is an experimental reactor that allows experiments with this magnetic confinement method.

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

Craig Bidler of the Max Planck Institute for Plasma Physics, who led the study, wondered if Wendelstein 7-X might have been improved for trapping plasma, but in fact had the desired effect, and the investigation has begun.

the previousExperimentA thought experiment was performed based on the plasma discharge data generated in, and under the assumption that “if Wendelstein 7-X is not improved”, the plasma loss exceeded the heating capacity. With this in mind, Mr. Biedler concluded that “optimal Wendelstein 7-X succeeded in reducing plasma loss.”

“The purpose of fusion research is to develop environmentally and climate-friendly power plants,” Weidler said, with the goal of raising the confinement quality of Wendelstein 7-X plasma to the level of competing tokamak facilities.
