TL;DR
The paper proposes the KLASH experiment to search for galactic axions around 0.2 microeV using a large, cooled resonant cavity within a magnetic field, aiming to detect axion-to-photon conversion.
Contribution
It introduces a novel experimental setup with a large volume resonant cavity and specific parameters to improve sensitivity to QCD axions.
Findings
Potential sensitivity to axion-photon coupling of 6x10^-17 GeV^-1
Reaches the parameter space predicted by KSVZ and DFSZ models
Utilizes existing superconducting magnet infrastructure
Abstract
We propose a search of galactic axions with mass about 0.2 microeV using a large volume resonant cavity, about 50 m^3, cooled down to 4 K and immersed in a moderate axial magnetic field of about 0.6 T generated inside the superconducting magnet of the KLOE experiment located at the National Laboratory of Frascati of INFN. This experiment, called KLASH (KLoe magnet for Axion SearcH) in the following, has a potential sensitivity on the axion-to-photon coupling, g_agg, of about 6x10^-17 GeV-1, reaching the region predicted by KSVZ and DFSZ models of QCD axions.
