✦ Synopsis

We report the status of the ORPHEUS dark matter experiment. The detector will consist of about 1 kg of superheated superconducting Tin granules and will be operated below 0.5 K. Measurements with a 32 cm3 target, read by a single SQUID channel, are presented. Experience has been gained with cryogenic tests, performed with a test detector chamber, mounted via a side access to the cryostat.
