中国散裂中子源（CSNS）快速循环同步加速器（RCS）横向准直系统预计准直效率超过95%。横向准直系统是一个两级准直系统，包括一个初级准直器和一些次级准直器。这里，推导了二维情况下CSNS/RCS的准直效率。清晰地显示了准直效率与相位超前和散射角之间的关系。最后，准直器使用 ORBIT 代码进行优化。
The transverse collimation system of the Chinese Spallation Neutron Source (CSNS) Rapid Cycling Synchrotron (RCS) is expected to have a collimation efficiency of over 95%. The transverse collimation system is a two-stage collimation system, including a primary collimator and some secondary collimators. Here, the collimation efficiency of CSNS/RCS is deduced in the 2D case. The relationship between the collimation efficiency with phase advances and scattering angle is clearly shown. Finally, collimators are optimized with ORBIT code.
