由于其精确已知的味道含量和光谱，储存环中μ子衰变产生的中微子束将成为精确测量中微子横截面和寻找无菌中微子的理想工具。在拟议中的nuSTORM设施中，π介子将直接注入赛道储存环，在那里循环的μ介子束将被捕获。在本文中，我们表明，一个μ子衰变环的基础上的跑道缩放FFAG（固定场交替梯度）与三重聚焦结构是一个非常有前途的选择，具有潜在的优势，基于FODO的解决方案。我们讨论了环的概念，机器参数，线性光学设计，光束动力学和注入系统。
The neutrino beam produced from muons decaying in a storage ring would be an ideal tool for precise neutrino cross section measurements and the search for sterile neutrinos due to its precisely known flavour content and spectrum. In the proposed nuSTORM facility, pions would be directly injected into a racetrack storage ring, where the circulating muon beam would be captured. In this paper we show that a muon decay ring based on a racetrack scaling FFAG (Fixed Field Alternating Gradient) with triplet focusing structures is a very promising option with potential advantages over the FODO based solution. We discuss the ring concept, machine parameters, linear optics design, beam dynamics and the injection system.
