Abstract
A spherical magnetically shielded room called COSMOS and a method for measuring the shielding factor of well-shielded rooms have been develo ped. A dc-superconducting quantum interference device is used to detec t faint magnetic fields, and the detected signals are averaged to incr ease-the signal-to-noise ratio. The measured magnetic shielding factor for COSMOS is 420 000 at 1 Hz.
