Multicavity array searches for 2-4 GHz axions with ADMX-EFR

ORAL

Abstract

Axions dark matter is a hypothetical particle that can solves both the Strong CP problem and is a candidate for the dark matter in the Universe. Axion haloscopes search for axion dark matter through its coupling to photons in a strong magnetic field. At higher axion masses, the sensitivity of axion haloscopes decreases. The Axion Dark Matter eXperiment-Extended Frequency Range (ADMX-EFR) is a 2-4 GHz axion haloscope that will utilize an 18-cavity array. We will present updates on the status of ADMX-EFR.
