在原有的ＨＩＲＦＬＳＦＣ引出系统基础上，设计了两个无线圈磁通道。一个通道将ＳＦＣ边缘场改变成正梯度的线性分布场，使引出束流在径向聚焦；另一个通道屏蔽一部分边缘场，使引出束向大半径方向偏转；此外，还设计了１２０°对称的假磁通道，以平衡磁通道给ＳＦＣ带来的一次谐波扰动场。实际的测磁结果表明，磁通道达到了设计的理论要求。此设计完善了ＳＦＣ束流引出系统。 Based on the original HIRFLSFC extraction system, two coilless magnetic paths are designed. One channel changes the SFC fringe field into a positive gradient linearly distributed field, which causes the outgoing beam to focus in the radial direction. The other channel shields a part of the fringe field, which deflects the outgoing beam to a large radius. In addition, a 120 ° symmetrical fake Magnetic channel to balance the magnetic resonance path to the SFC harmonic. The actual magnetometry results show that the magnetic channel to achieve the theoretical design requirements. This design improves the SFC beam extraction system.
