对于地面引力波（GW）探测器来说，大气中的雷击是环境噪声的来源。一些 GW 探测器是在地下设施中建造或规划的，人们对了解雷击如何影响它们很感兴趣。本文介绍了KAGRA的雷电探测系统，并展示了KAGRA隧道内外测得的磁场特性。还显示了 KAGRA 主干涉仪的 GW 通道中的一次雷电诱发事件。最后，讨论了闪电事件在引力波实验中的可能应用。
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 showed. Finally, possible applications of lightning events for the GW experiments are discussed.
