Noise Suppression with Cryogenic Resonators
Eugene N. Ivanov, Michael E. Tobar
We show that fast technical fluctuations of microwave signals can be strongly suppressed by cryogenic resonators. The experiments were carried out with sapphire resonators cooled t…
Power-to-Frequency Conversion in Cryogenic Sapphire Resonators
Eugene Ivanov, Michael Tobar
We studied how the cryogenic sapphire resonator responds to fast variations of the dissipated microwave power. The experiments were carried out with sapphire resonators cooled to 6…
Searching for Low-Mass Axions using Resonant Upconversion
Catriona A. Thomson, Maxim Goryachev, Ben T. McAllister +3
We present new results of a room temperature resonant AC haloscope, which searches for axions via photon upconversion. Traditional haloscopes require a strong applied DC magnetic b…
Comparing Instrument Spectral Sensitivity of Dissimilar Electromagnetic Haloscopes to Axion Dark Matter and High Frequency Gravitational Waves
Michael E. Tobar, Catriona A. Thomson, William M. Campbell +5
It is known that haloscopes that search for dark matter axions via the axion-photon anomaly are also sensitive to gravitational radiation through the inverse Gertsenshtein effect.…
Direct Search for Dark Matter Axions Excluding ALP Cogenesis in the 63-67 micro-eV Range, with The ORGAN Experiment
Aaron P. Quiskamp, Ben T. McAllister, Paul Altin +3
The standard model axion seesaw Higgs portal inflation (SMASH) model is a well motivated, self-contained description of particle physics over a range of energy scales that predicts…
Low Noise Microwaves for Testing Fundamental Physics
Eugene Ivanov, Michael Tobar
We studied noise properties of microwave signals transmitted through the cryogenic resonator. The experiments were performed with the 11.342 GHz sapphire loaded cavity resonator co…
