METHOD FOR SIMULTANEOUS GENERATION OF A MAGNETIC FIELD AND THERMAL STABILIZATION OF A QUANTUM ROTATION SENSOR AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G01N24/08 

FIELD: gyroscopes.

SUBSTANCE: invention is based on the phenomenon of nuclear magnetic resonance, namely to a means of simultaneous generation of a magnetic field and thermal stabilization of a quantum rotation sensor. The device contains a solenoid, gas cells (GC), a temperature sensor, transverse field receiving coils, a transverse field signal amplifier, a temperature sensor error signal amplifier, a controller for controlling temperature and Larmor precession frequency in transverse coils. Two DC sources are connected to the controller output, loaded on the windings of direct and reverse currents (i₁, i₂) of the solenoid to provide total and differential currents for stabilizing the temperature and magnetic field. As a result of processing input signals, controller 9 generates control signals at outputs 1 and 2 such that DC sources 10 and 11 generate currents i₁ and i₂, respectively, allowing in total (i₁+i₂) to heat cell 2 to temperature T₀ with retention it at the level of accuracy required for a quantum system, and the difference current (i₁-i₂) to create and maintain a constant magnetic field B_z at the required level of accuracy.

EFFECT: getting rid of parasitic magnetism created by the heater and uncontrolled heating created by magnetic coils.
