The Klash Proposal: Status and Perspectives

Abstract

Recently some of the authors proposed a search for galactic axions with mass about 0.2~$μ$eV using a large volume resonant cavity, tens of cubic meters, cooled down to 4~K and immersed in a 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), has a potential sensitivity on the axion-to-photon coupling, $g_{aγγ}$, of about $6\times10^{-17}$ $\mbox{GeV}^{-1}$, reaching the region predicted by KSVZ\cite{KSVZ} and DFSZ\cite{DFSZ} models of QCD axions. We report here the status of the project.
