The Cryogenic System of DMRadio-50L
V. Ankel, C. Bartram, J. Begin +36
The DMRadio-50L experiment is designed to search for axion dark matter in the 5 kHz - 5 MHz frequency range using a lumped-element LC resonator and a toroidal magnet and to serve a…
DMRadio-Core: A new approach for GUT-scale axion searches
V. Ankel, C. Bartram, J. Begin +33
Searches for QCD axions with masses in the neV/ mass range are strongly motivated by new physics at the GUT scale and by well-motivated pre-inflationary axion symmetry breakin…
Extended Haloscope Search and Exclusion of a Candidate Signal near 1.036 GHz
Saebyeok Ahn, Boris I. Ivanov, Ohjoon Kwon +33
We report a follow-up axion haloscope search near 1.036 GHz that completes and extends our previous work [Phys. Rev. X 14, 031023 (2024)], in which a portion of the HEMT-based data…
Asymmetrical cavity design that bypasses mode mixings in axion haloscope experiments
Byeong Rok Ko, Andrew K. Yi
Microwave cavities used in axion haloscope experiments typically employ a tuning rod as a means to widen the range of resonance frequencies at which it is sensitive to axion-to-pho…
Axion dark matter searches from the standard halo over the tidal stream to the big flow
Andrew K. Yi, Byeong Rok Ko
The sensitivity of axion dark matter searches depends on the signal window that results from the velocity dispersion of axion dark matter. Since the ratio of signal windows is abou…
Maximizing Quantum Enhancement in Axion Dark Matter Experiments
Chao-Lin Kuo, Chelsea L. Bartram, Aaron S. Chou +8
We provide a comprehensive comparison of linear amplifiers and microwave photon-counters in axion dark matter experiments. The study is done assuming a range of realistic operating…
Improved Receiver Noise Calibration for ADMX Axion Search: 4.54 to 5.41 eV
M. Guzzetti, D. Zhang, C. Goodman +48
Axions are a well-motivated candidate for dark matter. The preeminent method to search for axion dark matter is known as the axion haloscope, which makes use of the conversion of a…
Enhanced tunable cavity development for axion dark matter searches using a piezoelectric motor in combination with gears
A. K. Yi, T. Seong, S. Lee +5
Most search experiments sensitive to quantum chromodynamics (QCD) axion dark matter benefit from microwave cavities, as electromagnetic resonators, that enhance the detectable axio…
Extensive search for axion dark matter over 1\,GHz with CAPP's Main Axion eXperiment
Saebyeok Ahn, JinMyeong Kim, Boris I. Ivanov +33
We report an extensive high-sensitivity search for axion dark matter above 1\,GHz at the Center for Axion and Precision Physics Research (CAPP). The cavity resonant search, exploit…
Analytical estimation of the signal to noise ratio efficiency in axion dark matter searches using a Savitzky-Golay filter
A. K. Yi, S. Ahn, B. R. Ko +1
The signal to noise ratio efficiency in axion dark matter searches has been estimated using large-statistic simulation data reflecting the background information and…
Electromagnetic modeling and science reach of DMRadio-m
DMRadio Collaboration, A. AlShirawi, V. Ankel +45
DMRadio-m is an experiment that is designed to be sensitive to KSVZ and DFSZ QCD axion models in the 10--200\,MHz (41 neV -- 0.83 eV/) range. The experiment uses…
Search for the Sagittarius Tidal Stream of Axion Dark Matter around 4.55 eV
Andrew K. Yi, Saebyeok Ahn, Çağlar Kutlu +29
We report the first search for the Sagittarius tidal stream of axion dark matter around 4.55 eV using CAPP-12TB haloscope data acquired in March of 2022. Our result excluded the…
