Abstract:

http://kiw8.org/program/

For ground-based gravitational-wave (GW) detectors, lightning strokes in the atmosphere are sources of environmental noise. Some GW detectors are constructed or planned in underground facilities, and knowledge of how lightning strokes affect them is of interest.
This talk is based on our paper: First, the lightning detection system in KAGRA is introduced. Second, the properties of the magnetic field measured inside and outside the KAGRA tunnel are shown. Third, one lightning-induced event in the GW channel of the KAGRA main interferometer is also exhibited.
