Abstract:
We report on the realization and characterization of a system for the simultaneous stabilization and control of magnetic field strength and gradient in a region of 35mm and along a given direction. The system is based on two magnetometers, each providing a field readout every 10μs, and a control unit, which real-time processes the readouts and controls the currents flowing into two compensation coils. Attenuations of 30dB for the field strength and 20dB for the gradient have been achieved, along with feedback loop bandwidths of 450 and 620Hz, respectively. The method can be extended in order to noninvasively control the field strength and gradient along all three directions as well as higher-order multipole terms.
