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…

High-volume tunable resonator for axion searches above 7 GHz
Taj A. Dyson, Chelsea L. Bartram, Ashley Davidson +4
We present results from the first experimental demonstration of a tunable thin-shell axion haloscope. This novel geometry decouples the overall volume of the cavity-based resonator…
