The Study of Thermal Fluctuations in Microwave and Mechanical Resonators
Michael T Hatzon, Eugene N Ivanov, Aaron Quiskamp +1
We report high-resolution measurements of thermal fluctuations in microwave and mechanical resonators using a dual-channel readout system. The latter comprises a low-noise amplifie…
Frequency Stable Microwave Sapphire Oscillators
Eugene N. Ivanov, Michael E. Tobar
We show that state-of-the-art phase noise and high frequency stability could be simultaneously achieved in a microwave oscillator based on the sapphire-loaded cavity resonator. The…
Gravitational Wave Detection and Low-Noise Sapphire Oscillators
Michael Edmund Tobar
This thesis describes the development of an ultra-low noise sapphire resonator oscillator that is tunable over X-band. While undertaking this task the author has explained some int…
Testing local position and fundamental constant invariance due to periodic gravitation and boost using long-term comparison of the SYRTE atomic fountains and H-masers
M. E. Tobar, P. L. Stanwix, J. J. McFerran +8
The frequencies of three separate Cs fountain clocks and one Rb fountain clock have been compared to various hydrogen masers to search for periodic changes correlated with the chan…
Demonstration of a Dual Alkali Rb/Cs Atomic Fountain Clock
J. Guéna, P. Rosenbusch, Ph. Laurent +7
We report the operation of a dual Rb/Cs atomic fountain clock. 133Cs and 87Rb atoms are cooled, launched, and detected simultaneously in LNE-SYRTE's FO2 double fountain. The dual c…
Long Term Operation and Performance of Cryogenic Sapphire Oscillators
M. E. Tobar, E. N. Ivanov, C. R. Locke +12
Cryogenic Sapphire Oscillators (CSO) developed at UWA have now been in operation around the world continuously for many years. Such oscillators, due to their excellent spectral pur…
