“…A.1). The sensitivity of SSG detectors to minimumionising particles [19], X rays [20], and α particles [21,22] has been proved in past experiments. The response of SSG devices to nuclear recoil energies down to 1 keV has been explored irradiating SSG granules with a 70 MeV neutron beam [23].…”

The ORPHEUS dark matter detector is operating at our underground laboratory in Bern (70 m.w.e.). The detector relies on measuring the magnetic flux variation produced by weakly interacting massive particles (WIMPs) as they heat micron-sized superheated superconducting tin granules (SSG) and induce superconducting-tonormal phase transitions. In an initial phase, 0.45 kg of tin granules in a segmented detector volume have been used. In this paper a general description of the experimental set-up, overall performance of the detector, and first results are presented.

The response of Superheated Superconducting Granule (SSG) devices to nuclear recoils has been explored by irradiating SSG detectors with a 70MeV neutron beam. In the past we have tested Al SSG and more recently, measurements have been performed with Sn and Zn detectors. The aim of the experiments was to test the sensitivity of SSG detectors to recoil energies down to a few keV. In this paper, the preliminary results of the neutron irradiation of a SSG detector made of Sn granules 15-20µm in diameter will be discussed. For the first time, recoil energy thresholds of ∼1keV have been measured. 1
