The fluctuation of the magnetic field gradient around the test masses is the main source of magnetic noise in KAGRA [1]. However, the gradient has not been directly measured so far though the fluctuation of the uniform field were measured [2]. Thus, the purpose of this project is to measure the gradient fluctuation or set an upper limit to it. |
