我们描述和显示结果的摄影技术连续监测的位置,方向和形状的薄膜μ介子停止目标的MEG II实验Baldini等人。(2018年)。由于目标位于具有1.3 T磁场、显著正电子通量和有限访问的区域中,测量变得复杂。该技术实现了10 μ m垂直和30 μ m平行于膜表面的测量精度,明显优于MEG II实验的要求。
We describe and show results of a photographic technique for continuously monitoring the position, orientation, and shape of a thin-film muon stopping target for the MEG II experiment Baldini et al.(2018). The measurement is complicated by the target being located in a region with 1.3 T magnetic field, significant positron flux, and limited access. The technique achieves a measurement precision of 10 μ m normal to and 30 μ m parallel to the film surface, significantly better than required for the MEG II experiment.
