Measurement of the magnetic field gradient at the KAGRA site

Project description

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 [2,3]. Thus, the purpose of this project is to measure the gradient fluctuation or set an upper limit to it.
