| 摘 要： | 水冷磁体设计,须计算水冷磁体产生的磁场以获得磁体磁场的空间分布,使设计出的磁体满足实验要求.水冷磁体磁场计算在工程上常用的计算方法是椭圆积分法.此方法计算的水冷磁体的磁场均匀度比实际做成的磁体产生的磁场均匀度偏高.原因之一是磁体上的电流路径并不是工程上假设的闭合圆环路径,而是与之等半径的螺旋线状的路径.这是工程理论计算...

| Abstract: | Water-cooled magnet design requires calculating magnetic field and obtaining its distribution in space.A common method for calculating a water-cooled magnet's magnetic field in engineering is Elliptic integral method.The field homogeneity with this method is higher than that of a real water-cooled magnet.One of the reasons is that the current path in the magnet is not circular,but a helix one.This path is an important reason for field difference between engineering calculation and real magnet.Exploring a mo... |
