The choice for material of iron core, all the structure design and the method of collimation for the magnet were also described. Simulation results of Opera show that when the length of the core is 220 mm, the effective magnetic length is about 302 mm and the maximal magnetic density is around 0.215 T at four interior angles. Corresponding field uniformity is within 0.8% in the area of 133 mm×200 mm.

根据磁铁的设计指标，给出了磁铁设计要求铁芯材料选择方法、整体的结构设计以及如何对磁铁进行定位和准直，并采用Opera程序进行模拟计算，结果表明：当铁芯长度为220 mm时，磁有效长度大约为302 mm；磁感应密度最大的地方在4个内角上，约为0.215 T；在133 mm×200 mm的平面范围内，磁场均匀性优于±0.8%。
