nuSTORM（来自存储μ子的中微子）提案提出了一个基于μ子存储环的中微子设施的详细设计，在环的生产直线段中的μ子衰变提供了定义良好的中微子束。该设施包括一个初级高能质子束线，一个具有π介子生产和收集的目标站，以及一个用于π介子运输和注入μ介子衰变环的π介子束线。nuSTORM的设计使用了“随机注入”，其中π介子被一个称为轨道组合段（OCS）的弯道引导到储存环的生产直线段。在直线段内衰变的π介子在环的循环接受范围内提供μ介子。该设计使得注入没有反冲或单独的π衰变传输线。π介子在从衰变环中被提取出来之前穿过的束线被称为π介子束线。本文介绍了π介子光束线的设计和模拟，包括系统的全束流动力学模拟。
The nuSTORM (neutrinos from STORed Muons) proposal presents a detailed design for a neutrino facility based on a muon storage ring, with muon decay in the production straight section of the ring providing well defined neutrino beams. The facility includes a primary high-energy proton beam line, a target station with pion production and collection, and a pion beamline for pion transportation and injection into a muon decay ring. The nuSTORM design uses “stochastic injection”, in which pions are directed by a chicane, referred to as the Orbit Combination Section (OCS), into the production straight section of the storage ring. Pions that decay within that straight section provide muons within the circulating acceptance of the ring. The design enables injection without kickers or a separate pion decay transport line. The beam line that the pions traverse before being extracted from the decay ring is referred to as the pion beamline. This paper describes the design and simulation of the pion beamline, and includes full beam dynamics simulations of the system.
