Design and Optimization of Deuterium-Deuterium Fusion Neutron Source Large-Size and High Magnetic Field Magnetic Compression Magnet
摘要
Abstract
[Objectives]In order to truly reflect the damage characteristic of fusion neutron irradiation,it is necessary to carry out research on high-flux fusion neutron sources.As the first experimental device in the world that can realize cascaded magnetic compression with high compression ratio of field-reversed configuration plasma,the preliminary research device of magnetic confinement deuterium-deuterium fusion neutron source has important scientific significance.As one of the core components of the device,the magnetic compression magnet was designed to increase the magnetic induction intensity of the central magnetic field from 0 T to 7 T within 500 μs.Therefore,a design idea for the conductor part of the magnetic compression magnet was proposed.[Methods]Based on the conductor design of magnet,the conductor stress was analyzed by finite element simulation software from the three aspects of conductor material selection,conductor turn distance and conductor radial thickness.The influence of conductor material conductivity,conductor turn distance and conductor radial thickness on conductor stress was obtained.[Results]The design idea of the next magnet is determined.That is,the conductor material with low conductivity is appropriately selected within the allowable range of ohmic loss,the conductor turn spacing is appropriately increased by increasing the thickness of the insulation layer within the allowable range of axial space,and the radial thickness of the conductor is appropriately reduced within the allowable range of material stress to reduce the construction cost.[Conclusions]With the further development of the preliminary research device of neutron source project,the design ideas proposed in this paper can provide optimization direction for the design of magnetic compression magnet device.关键词
