Electromagnetic properties analysis on superconducting magnet coil for magnetoplasmadymamic thruster
摘要
Abstract
In engineering applications , the traditional water-cooled copper magnet coils providing applied field have many defects such as large volume , big mass and high power dissipation , so the application of tiny volume and small mass high temperature superconductor (HTS) coils on applied-field magnetoplasmadynamic thruster (AF-MPDT ) is focused on . An HTS coil by Bi-2333/Ag was designed to satisfy the demand of 0. 2 T center magnetic field strength which consists of three double pancake coils . The HTS coil is 30 mm in height , with a 160 mm inner diameter . To study the electromagnetic properties of the coil , a critical current testing system was built based on the principle of electric transport method . The experimental results show that different pancakes have different critical current IC , and middle pancake has the highest IC value . The iron plates have positive influence on the coil electromagnetic properties , and can improve IC value by 42% . Meanwhile , using electromagnetic simulation method , the effect of iron plates size and position on the performances of the HTS coil was researched , and an optimized design was summarized .关键词
