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…
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…
Cryogenic sapphire oscillator with exceptionally high long-term frequency stability
J. G. Hartnett, C. R. Locke, E. N. Ivanov +2
We report on the development of a sapphire cryogenic microwave resonator oscillator long-term fractional frequency stability of 2x10^-17Sqrt[τ] for integration times τ>10^3 s and n…
