The ORPHEUS dark matter experiment is being built and most of it is already
installed at our underground facility in Bern (70 m.w.e). The detector rel
ies in an initial phase on 0.45 kg (1.6 kg maximum capacity) superheated su
perconducting tin granules (SSG) to measure recoils from weakly interacting
massive particles (WIMPs). The actual status of the installation as well a
s parallel ongoing studies are presented.
