标题： The UV Laser Calibration System for measuring the Electric field in the SBND

摘要： 短基线近探测器（SBND）是一个液氩时间投影室（LArTPC）探测器，位于费米实验室的BOOSTER中微子束（BNB）110米处。 它的设计目的是测量中微子截面，并帮助寻找过量的类电子中微子事件。 SBND-TPC内部的电场可能由于多种原因产生畸变，例如空间电荷效应。 空间电荷效应来源于大量的宇宙射线，这些射线使氩气电离，产生大量正氩离子。 在这种情况下，我们需要一个替代解决方案来确定TPC体积内部的电场畸变，并补偿可能的空间信息畸变。 紫外激光系统就是这样一个尝试，用于确定电场畸变。 通过利用高能紫外线激光束，该系统可以绘制出TPC体积内的空间畸变图，并提供必要的校正以确保准确的空间和量热测量。 显示英文摘要

摘要： The Short Baseline Near Detector (SBND) is a LArTPC detector, located 110 meters from the Fermilab's Booster Neutrino Beam (BNB). It is designed to measure neutrino cross-section and aid in searches for excess electron like neutrino events. The electric field inside the SBND-TPC may have distortions due to a number of reasons, such as the space charge effect. The space charge effect comes from the abundance of cosmic rays that ionize the argon, producing copious positive argon ions. In this case, we need an alternative solution to determine the electric field distortion inside the TPC volume and compensate for the possible distortion in the spatial information. The UV Laser system is one such attempt to determine the electric field distortion. By utilising a high energy ultraviolet laser beam, the system can map the spatial distortions within the TPC volume and provide the necessary corrections to ensure accurate spatial and calorimetric measurements.
