摘　　要：描述了一种１８０°消色差等时性磁偏转系统，它由４个具有中心对称平面的二极磁铁构成。用传输矩阵方法研究了其消色差和等时性关系，并讨论了系统的二阶效应。该系统具有良好的等时性、消色差性及聚焦特性。其紧凑的结构尤为适于反射式加速器中束流的倒向传输。A doubly achromatic isochronous 180° deflection system is described. It consists of four dipoles with a middle symmetric plane. The achromatic and isochronous relations of the system are obtained with transport matrix method, and the second order effects are discussed.With good achromatic, isochronous and focus properties and compact configuration, the system is suitable for beam reversing transpot in refexotron.
