Search for Dark Matter utilizing a global network of optical magnetometers and Co-magnetometers.

The GNOME collaboration (Global Network of Optical Magnetometers to search for Exotic physics) is a network of geographically separated, time-synchronized, optically pumped atomic magnetometers and co-magnetometers that is being used to search for correlated transient signals, that may result from the passage of the earth through Dark Matter fields. Such a co-magnetometer is now being installed in Ben-Gurion University (BGU) as apart on an NSF-BSF project. A review of the GNOME network, with a detailed description of the BGU co-magnetometer, will be presented.
