论文摘要
MUON G-2存储环的一部分提供垂直光束聚焦，表现出意外的时间依赖性，在Fermilab（E989）的MUON G-2实验的Run-1期间产生了储存的光束的特征演化。已经开发了一种重建Run-1电向导向场的方法，该方法基于MUON存储环的数值模型和由舒适的Infinity支持的优化算法。该方法将光束轮廓测量从MUON G-2稻草跟踪探测器作为输入中，并对时间依赖性场产生完整的重建。然后，这些字段可用于复制详细的光束跟踪模拟，以及用于接受研究和系统误差评估的环晶格参数的计算。
A portion of the Muon g-2 Storage Ring electric system, which provides vertical beam focusing, exhibited an unexpected time dependence that produced a characteristic evolution of the stored beam during Run-1 of the Muon g-2 Experiment at Fermilab (E989). A method to reconstruct the Run-1 electric guide fields has been developed, which is based on a numerical model of the muon storage ring and optimization algorithms supported by COSY INFINITY. This method takes beam profile measurements from the Muon g-2 straw tracking detectors as input, and it produces a full reconstruction of the time-dependent fields. The fields can then be used for the reproduction of detailed beam tracking simulations and the calculation of ring lattice parameters for acceptance studies and systematic error evaluations.
