Abstract : The design, fabrication and test of the oscillating compact maser, CHYMNS-I, has been previously described. The objective of CHYMNS-1 was to demonstrate that a cavity Q-enhancement technique can be used to obtain sustained maser oscillation in a compact cavity. The superior signal-to-noise ratio of an oscillator and the simplified electronics would facilitate the development of a frequency standard of excellent performance. Obviously, an effective electronic cavity stabilization servo system would be essential to overcome the susceptibility of an external feedback system to environmental perturbations. On the other hand, such a system would provide improved long term maser performance compared to conventional masers where cavity stabilization is based on thermal/mechanical considerations. The objective of CHYMNS-I was successfully accomplished as described in Reference 1.
