A cryogenic RE oscillator, the heart of a new NMR dispersion spectrometer

Abstract
Describes a new CW-NMR dispersion spectrometer based on the detection of the frequency shift of a cryogenic tunnel diode oscillator, in which the inductance of the coil is influenced by the magnetic resonance phenomenon. Besides the design, the details of the construction and the operation of the oscillator, an outline of the performances and the major advantages and disadvantages of this spectrometer are given. The performances are compared with those of conventional NMR absorption (and dispersion) spectrometers.
