摘　　要：测量了HL-2A装置ECRH超导磁体的磁场分布。测量结果析表明,其归一化纵向磁场在磁场中心20mm区域内大于0.992,径向分布在磁场中心平面上浮动小于1.48%,杂散场在贴近超导磁体表面时的最大分量小于50mT,满足实验要求。Magnetic field distribution of the ECRH superconducting magnet on HL-2A tokamak has been measured, and the results show that the normalized axial magnetic induction is not less than 0.992 in the area of 20mm around the center, the fluctuation of magnetic field is not more than 1.48% on the whole center plane, the stray field near the magnet surface is not more than 50mT; and these satisfy the experiments.
