Characterization of the Mainz atomic magnetometer for GNOME — •Hector Masia, Samer Afach, Arne Wickenbrock, and Dmitry Budker — Johannes Gutenberg-Universität Mainz

GNOME is a novel experimental scheme which enables the investigation of exotic spin couplings between nuclei and exotic fields generated by astrophysical sources measuring spin precession. It consist of a network of geographically separated (>100km), time synchronized, ultrasensitive ( ∼ fT/ √Hz ) optical magnetometers in a magnetically shielded environment. Such a configuration enables the study of global transient effects.

Several atomic magnetometric setups are currently under construction around the globe in order to complete a reliable network for the successful characterization of hypothetical exotic fields. Here is presented the current work of the atomic magnetometer constructed in Mainz as a part of the GNOME collaboration. The main characteristics of the magnetometer, such as sensitivity, response to pulses, long term stability and sources of noise are discussed. These quantities are related to the sensitivity of the network to global transient effects.
