1 Oct 2020 | Abstract: | Axion Dark Matter eXperiment (ADMX) ultra low noise haloscope technology has
enabled the successful completion of two science runs (1A and 1B) that looked
for dark matter axions in the $2.66$ to $3.1$ $mu$eV mass range with
Dine-Fischler-Srednicki-Zhitnisky (DFSZ) sensitivity Ref. [1,2]. Therefore, it
is the most sensitive axion search experiment to date in this mass range. We
discuss the technological advances made in the last several years to achieve
this sensitivity, which includes the implementation of components, such as
state-of-the-art quantum limited amplifiers and a dilution refrigerator.
Furthermore, we demonstrate the use of a frequency tunable Microstrip
Superconducting Quantum Interference Device (SQUID) Amplifier (MSA), in Run 1A,
and a Josephson Parametric Amplifier (JPA), in Run 1B, along with novel
analysis tools that characterize the system noise temperature. | Source: | arXiv, 2010.00169 | Services: | Forum | Review | PDF | Favorites |
