Spectrometer for measuring spatial distributions of paramagnetic centers in solid bodies

摘要

A spectrometer is disclosed in which gradient coils are provided in order to create an inhomogeneous magnetic field for use in analyzing individual regions within the sample under examination. The gradient coils and the modulating coils are operated by discrete pulses, rather than continuously. A keying unit coordinates the interaction of the various components of the spectrometer in order to monitor resonance of the sample under examination while such pulses occur.
