EAST超导托卡马克是中国设计建造的国际上第一个建成的全超导托卡马克实验装置。超导磁体系统作为EAST的核心部件，主要由16组D形纵场磁体系统、14组极向场磁体系统组成。磁体在装配前进行了全面的测试，测试通过后才能安装到装置中。2006年间共进行了三次工程调试，其中包括三次降温通电实验和两次等离子体实验。本文将介绍EAST超导磁体测试实验以及EAST工程调试过程，同时也介绍磁体技术诊断系统、安全联锁系统与失超探测保护系统。

EAST (Experimental Advanced Superconducting Tokamak) is the first full superconducting Tokamak device in the world, it was designed and built in China. Superconducting magnet system is the core of EAST, comprises of 16 D-shape toroidal field (TF) coils and 14 poloidal field (PF) coils. Before assembling the device, each magnet should be fully test. During 2006，there are 3 times engineering commissioning, including 3 times cool down and charge experiment, 2 times plasma experiment. The test experiment and engineering commissioning of EAST superconducting magnets are introduced in this paper, magnet diagnosis system, safety interlock system and quench detection and protection system are also introduced.
