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…
