In this paper, analytic formula of magnetic field distribution of single magnet is derived by uniform magnetizing method. Based on this model, the magnet field distribution in the magnet pole gap of optical klystron (OK) is numerically simulated through a self made c language program. Transverse magnet field distributions on the axis are simulated, and transverse magnet field uniformity is calculated. Based on the data simulated, the feature parameter variation of the chromatic dispersive section in the OK is calculated when the magnet pole gap of the dispersive section varies.
