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…
A Non-Foster Superconducting Broadband Matching Network
Andrew K. Yi, Pamela Stark, Chelsea Bartram
The nonlinear inductance of the Josephson junction has enabled the development of a wide range of continuous-variable amplifiers and qubit-based devices with unprecedented sensitiv…
Noise limits for dc SQUID readout of high- resonators below 300 MHz
V. Ankel, C. Bartram, J. Begin +38
We present the limits on noise for the readout of cryogenic high- resonators using dc Superconducting Quantum Interference Devices (SQUIDs) below 300 MHz. This analysis uses rea…
Search for Axion Dark Matter from 1.1 to 1.3 GHz with ADMX
ADMX Collaboration, G. Carosi, C. Cisneros +50
Axion dark matter can satisfy the conditions needed to account for all of the dark matter and solve the strong CP problem. The Axion Dark Matter eXperiment (ADMX) is a direct dark…
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…
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…
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…
