Cavity-mode couplings in axion dark matter searches
Byeong Rok Ko
Axion dark matter searches use a microwave cavity for the resonant conversion of axions into photons to enhance experimental sensitivity, with the cavity generally configured as a…
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…
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…
Development of an FPGA-based realtime DAQ system for axion haloscope experiments
MyeongJae Lee, ByeongRok Ko, Saebyeok Ahn
A real-time Data Acquisition (DAQ) system for the CULTASK axion haloscope experiment was constructed and tested. The CULTASK is an experiment to search for cosmic axions using reso…
CAPP-8TB: Axion Dark Matter Search Experiment around 6.7 eV
J. Choi, S. Ahn, B. R. Ko +2
CAPP-8TB is an axion dark matter search experiment dedicated to an axion mass search near 6.7 eV. The experiment uses a microwave resonant cavity under a strong magnetic field o…
Improved axion haloscope search analysis
S. Ahn, S. Lee, J. Choi +2
One of the most significant and practical figures of merit in axion haloscope searches is the scanning rate, because of the unknown axion mass. Under the best experimental paramete…
