摘要:

瑞士保罗谢勒研究所的μ子散射实验(MUSE)通过同时测量弹性μ子-质子和电子-质子散射,研究质子电荷半径之谜、轻子普适性和双光子交换。该实验使用PiM 1次级光束通道,该通道专为高精度π介子散射测量而设计。我们回顾了π介子束线的性质。我们讨论了产生电子和μ子束的生产过程,以及对这些过程的模拟。比较了TURTLE和G4光束线对$π$/$μ$ / $e$光束通过通道的模拟结果。G4光束线模拟,然后比较几个实验测量的通道,包括在IFP和目标的动量色散,在目标的束斑的形状,并定时测量,使束动量被确定。我们得出结论,PiM 1通道可用于高精度$π$、$μ$和$e$散射。

英文摘要:

The MUon Scattering Experiment, MUSE, at the Paul Scherrer Institute, Switzerland, investigates the proton charge radius puzzle, lepton universality, and two-photon exchange, via simultaneous measurements of elastic muon-proton and electron-proton scattering. The experiment uses the PiM1 secondary beam channel, which was designed for high precision pion scattering measurements. We review the properties of the beam line established for pions. We discuss the production processes that generate the electron and muon beams, and the simulations of these processes. Simulations of the $π$/$μ$/$e$ beams through the channel using TURTLE and G4beamline are compared. The G4beamline simulation is then compared to several experimental measurements of the channel, including the momentum dispersion at the IFP and target, the shape of the beam spot at the target, and timing measurements that allow the beam momenta to be determined. We conclude that the PiM1 channel can be used for high precision $π$, $μ$, and $e$ scattering.
