摘要:
A Hall effect regulated electromagnet system can be locked to an NMR resonance by applying the NMR error signal to a small bias coil on the field sensor. The method requires no modification of the magnet regulator circuitry, produces negligible inhomogeneity near the center of the magnet, and reduces long term field drift to less than 1 mG if the NMR frequency is crystal controlled.
