Abstract

The invention relates to a method for manufacturing a fusion pellet based on a microfluid channel, in particular to a method for manufacturing an inertial confinement nuclear fusion pellet based on a microfluid channel technology. According to the method, dual microemulsion is formed by pellet solutions or a front fusion body in a flowing phase by adopting a microfluid channel network system, the inner diameter and the outer diameter of the dual microemulsion are adjusted in real time through an image collecting and analysis system and a flow control system, and finally a preset size is achieved. Then, hollow micro balls meeting the ICF target requirements are formed through curing and drying based on a liquid drop formwork. According to the manufacturing method, the hollow micro balls which are uniform in size and controllable in ball wall can be manufactured, and the ICF requirements are met. The manufacturing method particularly comprises the first step of manufacturing the microfluid channel, the second step of manufacturing the microemulsion, the third step of obtaining the size of the microemulsion, the fourth step of controlling the inner diameter and the outer diameter of the dual emulsion and the fifth step of manufacturing the fusion pellet.

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.
