    • A hollow exciting current pathway in the form of a conductor is arranged outside of an ion deflection casing with a curved contour and having an inlet and an outlet. The conductor is composed of a widthwise spiral formation of conductors running through the inlet and outlet and along the curved contour with a result that a magnetic field which is uniform widthwise is formed in the ion deflection casing. An ion beam is introduced through between the conductors at the inlet into the hollow exciting current pathway. By the action of the magnetic field through the hollow exciting current pathway, the ion beam is bent depending upon mass of ions. The ion beam with desired mass is taken out through between the conductors at the outlet with a result that an ion beam greater in size can be ion mass separated uniformly.
    • 以导体形式的中空激励电流通路设置在具有弯曲轮廓并具有入口和出口的离子偏转壳体的外部。 导体由沿着入口和出口延伸的导体沿着弯曲轮廓的宽度方向的螺旋形组成,结果是横向均匀地形成在离子偏转壳体中的磁场。 离子束通过入口处的导体之间引入中空激励电流通路中。 通过中空激励电流通路的磁场作用,离子束根据离子的质量而弯曲。 具有所需质量的离子束通过出口处的导体之间被取出,结果使得尺寸更大的离子束可以被均匀地离子质量分离。
