Journal ArticleDOI
Measurement and analysis of a microwave oscillator stabilized by a sapphire dielectric ring resonator for ultra-low noise
G.J. Dick,J. Saunders +1 more
TL;DR: Waveguide coupling parameters have been characterized for the principal (lowest frequency) mode family, for n=5 to n=10 full waves around the perimeter, and several mode families have been identified with good agreement with calculated frequency predictions.
Journal ArticleDOI
Temperature-compensated sapphire resonator for ultra-stable oscillator capability at temperatures above 77 K
TL;DR: In this article, a whispering gallery sapphire resonator for the dominant (WGH/sub n11/) microwave mode family shows frequency-stable, compensated operation for temperatures above 77 K. The resonator makes possible a new ultra-stable oscillator capability that promises performance improvements over the best available crystal quartz oscillators in a compact cryogenic package.
Journal ArticleDOI
Ultra-stable performance of the superconducting cavity maser
G.J. Dick,R.T. Wang +1 more
TL;DR: In this paper, the superconducting cavity maser (SCM) oscillator was reported to have frequency stability of parts in 10/sup 5/ for times from 1 s to 10000 s and phase noise of approximately -80 dB/f/sup 3/ was measured.
Journal ArticleDOI
Linear ion trap based atomic frequency standard
TL;DR: In this article, a trapped-ion-based fieldable frequency standard with a stability of 4*10/sup -13/square root tau for averaging times tau > was proposed.
Journal ArticleDOI
Ultra-stable Hg(+) trapped ion frequency standard
TL;DR: A fieldable frequency standard based on 199Hg+ ions confined in a hybrid r.f/dc linear ion trap was proposed in this paper, which allowed storage of large numbers of ions with reduced susceptibility to the second-order Doppler effect caused by the r. f. confining fields.
