介绍了基于中国空间中子源（CSNS）质子束流的首个表面μ子源的概念设计。本文计算了固体μ子靶的最佳参数，其中用蒙特卡罗模拟方法得到了最佳μ子束流参数，如束流速度、动量扩展和相空间分布。设计了一个简单的μ子传输束线系统，将μ子靶发射的μ子传输到实验区，利用谱仪检测样品中μ子衰变产生的正电子。文中还介绍了这种新光束线的光束光学。
This paper presents a conceptual design for the flrst tentative surface muon source based on the proton beam provided by China Spallation Neutron Source (CSNS). We have calcu- lated the optimal parameters of solid muon target, in which the method of Monte Carlo simula- tion is used to obtain the optimal muon beam parameters, such as beam ∞uence rate, momentum spread and phase space distribution. A simple muon transport beamline system was also designed, which could transport the muons emitted from the muon target into the experimental area, where positrons from muon decay in a test sample are detected by a spectrometer. The beam optics of this new beam line is also described.
