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…
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…
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…
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…
