Abstract
A simple super‐regenerative oscillator that produces a coherent signal at the magnetic resonance frequency of a sample in its coil is described in theory and in practice. A cw oscillator is phase locked to the super‐regenerative oscillator and the signal which results follows variations in the frequency of magnetic resonance, owing to variations of the field, within less than 5 parts in 103; the signal produced is adequately monochromatic and stable enough to be used for magnetic resonance experiments with high resolution. The requirements for time and temperature stabilization of the magnet are very greatly relaxed.Keywords
