Measurement of Schumann Resonance at Kamioka


On the stochastic gravitational-wave search, correlated noise in two or more gravitational-wave detectors can be a serious problem. Schumann resonance is the name of a standing wave of electromagnetic fields, which is one of the correlated noise sources for the second-generation gravitational-wave detectors. We measured the noise levels of the environmental magnetic field both inside and outside the mine of KAGRA site at Kamioka. In this letter, we report the result of the measurement and compare the amplitude of magnetic fields inside and outside the mine to find possible issues or gain of constructing a detector underground.
