Description
The FUNK (Finding $U(1)$s of Novel Kind) experiment was built to search direct
evidences for hidden-photon (HP) dark-matter. We use a $15\,\mathrm{m}^2$ spherical
metallic mirror as a HP-to-photon converter via Maxwellian-like transition.
Signals are expected to come together as single photon events at the radius
point where we mounted a low-noise photomultiplier.
We scanned the whole optical range of frequencies with extension in far-UV
and looked for HP with masses between 2 and 8 eV.
In our preliminary results, we found no events excess but provide the
up-to-date strongest limit for HP direct searches in this region.
