Abstract:
The possibility of creating a new scheme of a laser-pumped quantum magnetometric device based on a double-beam $M_X$ magnetometer is considered. The proposed system ensures the simultaneous measurement of the modulus of the Earth's magnetic field vector (with an absolute accuracy of 0.02 nT) and two angles of deviation of this vector with an absolute accuracy and sensitivity of not worse than 0.4" (0.1 nT) at a measurement time of $\tau$ = 1 s. In contrast to the known analogous systems, the proposed scheme does not require generating additional magnetic fields.
