In principle, this will cause a large neoclassical transport loss, resulting in a lower confinement performance than the tokamak, which is the main reason why the traditional stellarator has not become the international mainstream magnetic confinement fusion configuration

Embodiment Construction
[0053] The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.
[0054] The applicant has designed a quasi-circular symmetric stellarator that combines the advantages of tokamak and traditional stellarator, specifically as follows: Image 6 As shown, the quasi-circular symmetric stellarator includes a coil system 200, a vacuum system 300 and a support system 400, and the vacuum system 300 includes a vacuum chamber.
[0055] A divertor 100 for a quasi-circular symmetric stellarator proposed in this embodiment, such as Figure 1 to Figure 5 As shown, the divertor 100 is an important component of the vacuum system 300. The function of the divertor is to introduce particle flow and heat flow into the target plate area of the divertor through magnetic lines of force under the plasma configuration with magnetic islands, so as...

The invention relates to the technical field of magnetic confinement nuclear fusion equipment, in particular to a divertor used for a quasi-circular symmetric stellarator and a design method thereof. The divertor includes a baffle plate, a support structure, a first target plate and a second target Plate, the first target plate is located between the baffle plate and the second target plate, the first target plate and the second target plate are both used to receive particle flux and heat flux, and the support structure passes through the baffle plate and the star simulator. Vacuum chamber connection. The divertor proposed by the invention is a special three-dimensional target plate structure designed for the quasi-ring symmetrical stellarator, which can introduce particle flow and heat flow into the target plate area of the divertor through the magnetic force line under the plasma configuration with magnetic islands. Excluding the heat energy and impurities generated by the fusion reaction, its design and manufacture can help build the world's first quasi-circular symmetric magnetic confinement stellarator device, providing an experimental platform for domestic three-dimensional plasma physics and scientific research in related disciplines. The development and research of confinement fusion is of great significance.
Description
technical field [0001] The invention relates to the technical field of magnetic confinement nuclear fusion equipment, in particular to a device for a stellarator, in particular to a divertor for a quasi-circular symmetric stellarator and a design method thereof. Background technique [0002] With the development and progress of society, the demand for energy is increasing, and the world energy crisis is getting worse day by day. In the existing energy system, traditional non-renewable energy sources such as coal, oil, and natural gas are the main sources. These energy sources not only cause huge pollution to the environment during use, but also have a very limited number of years of use. Therefore, in order to maintain the high-speed sustainable development of human society, safe and abundant clean energy must be developed. Controlled nuclear fusion energy is such an energy source, which is recognized as the best way to solve the human energy crisis because of its abundant ...
