摘要
液氩时间投影室（LArTPCs）因其高材料密度、精确径迹重建和量能能力，已成为进行加速器 neutrino 测量的标准探测器技术。此类探测器需要电场（E-field）将电离电子漂移至阳极并被收集。TPC 的电场通常近似为在阳极与阴极平面之间均匀。然而，机械变形、电极失效或宇宙射线产生的空间电荷积累等效应会引起显著畸变。后者对于靠近地球表面放置、具有大漂移距离和长漂移时间的探测器尤为相关。为原位确定电场，费米国家加速器实验室的 MicroBooNE 实验中安装了紫外（UV）激光系统。该系统的目的是提供电场的精确测量，并校正由电场非均匀性引起的三维空间畸变。本文描述了根据 UV 激光测量推导空间畸变、漂移速度和电场的方法。
