标题： Effects of lightning strokes on underground gravitational waves observatories

摘要： 对于地基引力波（GW）探测器，大气中的闪电是环境噪声的来源。 一些引力波探测器建在或计划建在地下设施中，了解闪电如何影响它们是有意义的。 本文介绍了 KAGRA 中的闪电探测系统，并展示了在 KAGRA 隧道内外测量到的磁场特性。 此外，还展示了一个 KAGRA 主干涉仪引力波信道中由闪电引起的事件。 最后，讨论了闪电事件在引力波实验中的潜在应用。 显示英文摘要

摘要： For ground-based gravitational wave (GW) detectors, lightning strokes in the atmosphere are sources of environmental noise. Some GW detectors are built or planned in underground facilities, and knowledge of how lightning strokes affect them is of interest. In this paper, the lightning detection system in KAGRA is introduced, and the properties of the magnetic field measured inside and outside the KAGRA tunnel are shown. One lightning-induced event in the GW channel of the KAGRA main interferometer is also shown. Finally, possible applications of lightning events for the GW experiments are discussed.
