Abstract

A large magnetically shielded room has been constructed. It consists of three concentric cubic shields, each made of soft magnetic material and aluminum. The room utilizes ferromagnetic and eddy-current shielding, active noise compensation, and shaking to achieve a shielding factor of about 400,000 between 1 Hz and 100 Hz. The residual magnetic field in the room is less than 5 nT, and the internal magnetic noise above 0.5 Hz is lower than that of a standard SQUID magnetometer.
