Abstract

A preparation method for a fusion targeting pill based on microfluid control passage is provided, which is related in particular to a preparation method for an inertial restraint fusion targeting pill based on microfluid passage technology. The method adopts microfluid passage network to ensure the targeting pill solution or a pre-agglomerated body form double microemulsion fluid in flowing phase, form a hollow targeting pill that complies with the fusion requirements while basing on a liquid drop template and the diameter and wall thickness of the hollow targeting pill can be controlled. This preparation method ensures the solution or the pre-agglomerated body of the targeting pill material form double microemulsion via the microfluid passage, then forms a hollow microsphere that complies with ICF target requirement via solidification and drying. This preparation method is able to prepare hollow microsphere with even size and controllable sac wall and in compliance with ICF target requirement. The specific preparation method comprises: 1) preparation of microfluid passage; 2) preparation of microemulsion; 3) preparation of fusion targeting pill.

Description

technical field [0001] The invention relates to a method for preparing an inertial confinement nuclear fusion target pellet based on microfluidic channel technology, and belongs to the technical field of fusion target pellet preparation. Background technique [0002] As energy issues become increasingly prominent, inertial confinement fusion (ICF), as a controllable fusion technology, has received more and more attention. Countries such as Europe, America and Japan are conducting research on inertial confinement fusion. As the carrier of nuclear fusion fuel, the research and development of fusion target with hollow microsphere structure is an important content in ICF research. At present, the preparation techniques of target pellets mainly include: droplet furnace technology, xerogel technology, microencapsulation technology, interfacial polymerization method, etc. These methods usually require high-precision instruments, often consume a lot of raw materials, and are cumbe...
