Limiter for quasi-ring symmetric star simulator and design method thereof

The invention relates to the technical field of magnetic confinement nuclear fusion equipment, in particular to a limiter for a quasi-ring symmetrical star imitator and a design method thereof.The limiter comprises a supporting structure, a heat sink and a tile, the heat sink is in a long strip shape, and the cross section of the tile is of a semi-surrounding structure and wraps and is clamped on the heat sink; the limiter is a special limiter structure designed for a quasi-ring symmetric star simulator, the limiter structure can be matched with a vacuum chamber of a three-dimensional curved surface structure and the outermost closed magnetic surface of the star simulator, and in the operation process of a fusion reactor, high-temperature plasma is isolated from the first wall of the vacuum chamber through the limiter, so that high-temperature plasma is separated from the second wall of the vacuum chamber; the first wall is protected from being damaged by heat flow from plasma, electromagnetic radiation and t
