Description
We recently proposed [arXiv:1707.06010] a search of galactic axions with mass about 0.2 $\mu$eV using a
large volume resonant cavity, tens of cubic meters, 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), has a
potential sensitivity on the axion-to-photon coupling, $g_{a\gamma\gamma}$, of
about $6\times10^{-17}$ $\mbox{GeV}^{-1}$, reaching the region predicted by
KSVZ and DFSZ models of QCD axions.
We will present the results of detailed mechanical and electromagnetic simulations of the cryostat
and resonant cavity and improved studies of the Squid amplifier and of the tuning system.
We will then discuss the discovery potential of axions and other light particles with this realistic
setup and the strategies to extend the bandwith from 50 MHz foreseen in the original proposal
to hundreds MHz.
