Axion Dark Matter eXperiment (ADMX) Generation-2: Practical Realization of a DFSZ Sensitive Haloscope

ORAL

Abstract

Axions are a well motivated cold dark matter candidate. Axion haloscopes, such as the Axion Dark Matter eXperiment (ADMX), use the conversion of axions to photons in the presence of a magnetic field to search for dark matter axions. A haloscope’s sensitivity requires measuring minute signals with extremely low noise. The quantum electronics and cryogenics used to achieve sufficiently low system noise temperature to be sensitive to the GUT-compatible DFSZ axion coupling model in ADMX will be described.
