Resonator Power to Frequency Conversion in a Cryogenic Sapphire Oscillator
Nitin R. Nand, Stephen R. Parker, Eugene N. Ivanov +3
We report on the measurement and characterization of power to frequency conversion in the resonant mode of a cryogenic sapphire loaded cavity resonator, which is used as the freque…
Hidden Sector Photon Coupling of Resonant Cavities
Stephen R. Parker, Gray Rybka, Michael E. Tobar
Many beyond the standard model theories introduce light paraphotons, a hypothetical spin-1 field that kinetically mixes with photons. Microwave cavity experiments have traditionall…
Comparison of ultra-stable radio frequency signals synthesized from independent secondary microwave frequency standards
John G. Hartnett, Stephen R. Parker, Eugene N. Ivanov +3
The phase noise and frequency stability measurements of 1 GHz, 100 MHz, and 10 MHz signals are presented which have been synthesized from microwave cryogenic sapphire oscillators u…
