摘　　要：给出了直线感应加速器在磁体失准情况下电子束质心运动轨迹的计算机模型.利用坐标变换求磁体失准后的三维磁场分布,并采用束包络方程和束心偏移方程耦合求解的方法计算束心的运动轨迹.磁体失准度与束流质心偏移的定量关系的计算研究对磁体安装定位及校正线圈使用是有意义的.A model of the beam centroid motion in a linear induction accelerator（LIA） was developed. It calculatos the track of the beam centroid under the condition of cell magnet misalignment. The 3D magnetic field distribution is calculated with a coordinate transform. The track of the beam centroid is given by a coupled solution of the beam centroid and envelope equations. Quantitative relation between the transverse displacement of beam centroid and the misalignment of magnets is useful in the installation of magnets and the adjustment of steering coils.
