Abstract

The invention provides an infiltrating spherical shell for a low-temperature freezing target and a preparation method thereof, and the infiltrating spherical shell is characterized in that a basic unit is a regular tetrahedron structure, the regular tetrahedron structure is composed of solid prisms, the interior of the regular tetrahedron structure is a hollow structure, and the hollow structure is used as a liquid flowing and filling space; a micro-column or hydrophilic structure is arranged in the regular tetrahedral structure. The multiple basic units are arranged in a close packing mode to form an integral spherical shell structure. The spherical shell is prepared based on 3D printing, transportation and infiltration of liquid on the surface of the structure are achieved through the capillary force effect between the microstructures, meanwhile, the surface of the structure can be further modified, and therefore the liquid infiltration effect is effectively improved. The method does not need complex preparation steps, the process is simple and convenient, and the cost is low.

Description

technical field [0001] The invention relates to the preparation of a low-temperature frozen target, in particular to a spherical shell of a low-temperature frozen target with wettability to deuterium-tritium liquid and a preparation method thereof. Background technique [0002] The cryogenically frozen spherical shell target containing a uniform deuterium-tritium (DT) liquid fuel layer inside is one of the ideal implosion target types for inertial confinement fusion (ICF). The key to obtaining a cryogenically frozen target is to form a uniform thickness, A layer of frozen fuel with a smooth surface. At present, there are two main methods for forming the internal fuel layer of the frozen target: one is to directly freeze the target pellet system filled with fuel gas through external low temperature technology, obtain a solid or liquid fuel layer deposited on the surface of the target pellet, and then use the thermal gradient method , U layering technology, plasma layering te...
