CYCIAE-100为中国原子能科学研究院正在建设的紧凑型强流回旋加速器,采用剥离引出的方式双向引出能量范围75～100MeV的质子束,然后利用引出开关磁铁将不同能量的引出束流偏转到同一条公共的束流管道中,再经过开关磁铁分配到不同的试验终端。由于引出区域的色散效应,需要在束流引出后尽早安排聚焦元件以防止束流过分发散。因此,该引出开关磁铁放置于磁轭内部以减小束流引出点与聚焦元件的距离。引出束流轨迹跟踪的结果显示,该开关磁铁所需的最大磁场为0.5T,最大偏转角度6.2o。经磁铁优化设计,最终选择该磁铁的有效长度322mm,最大偏转半径约2970mm,磁极间隙80mm。
CYCIAE-100 is a compact high-intensity cyclotron currently under construction at China Institute of Atomic Energy. The proton beams with the energy range of 75-100 MeV are bi-directionally extracted by means of stripping and exiting, and then the outgoing switching magnets are used to deflect the outgoing beams with different energies to the same A common beam pipe, and then through the switching magnet assigned to a different test terminal. Due to the chromatic dispersion effect of the extraction region, the focusing element needs to be arranged as soon as possible after the extraction of the beam to prevent the beam from flowing through the dispersion. Therefore, the lead-out switching magnet is placed inside the yoke to reduce the distance between the beam extraction point and the focusing element. The results of the trajectory tracking of the outgoing beam show that the maximum magnetic field required by the switching magnet is 0.5T and the maximum deflection angle is 6.2o. The optimized design of the magnet, the final choice of the effective length of the magnet 322mm, the maximum deflection radius of about 2970mm, pole gap 80mm.
