摘要：

A multichannel atomic magnetometer operating in an unshielded environment is described and characterised. The magnetometer is based on D-1 optical pumping and D-2 polarimetry of Cs vapour contained in gas-buffered cells. Several technical implementations are described and discussed in detail. The demonstrated sensitivity of the setup is 100 fT/root Hz when operating in the difference mode.
