“…The calculated energy thresholds for 25µm Al, 29µm Zn and 17µm Sn granules are shown in Fig.5. The recoil energies due to neutral-current scattering of dark matter are expected to be of the order of a few keV [5]. Note that such energy thresholds can be reached with the presently used superconducting granules and in principle even lower ones could be reached using smaller granules.…”

This work is part of an ongoing project to develop a Superheated Superconducting Granule (SSG) detector for cold dark matter and neutrinos. The response of SSG devices to nuclear recoils has been explored irradiating SSG detectors with a 70MeV neutron beam. The aim of the experiment was to test the sensitivity of Sn, Al and Zn SSG detectors to nuclear recoil energies down to a few keV. The detector consisted of a hollow teflon cylinder (0.1cm 3 inner volume) filled with tiny superconducting metastable granules embedded in a dielectric medium. The nuclear recoil energies deposited in the SSG were determined measuring the neutron scattering angles with a neutron hodoscope. Coincidences in time between the SSG and the hodoscope signals have been clearly established. In this paper the results of the neutron irradiation experiments at different SSG intrinsic thresholds are discussed and compared to Monte Carlo simulations. The results show that SSG are sensitive to recoil energies down to ∼1keV. The limited angular resolution of the neutron hodoscope prevented us from measuring the SSG sensitivity to even lower recoil energies. PACS numbers: 95.30.C, 07.62 a present address:

“…Integrating over that region could hide a fluctuation that might actually be present in the data. The cross-over energy depends on the mass of the WIMP [26][27][28] and other parameters [28,29]. This experiment integrated up to a large final energy (50 keV) -consistent with the mean energy deposited by a 10 TeV WIMP-and ramped the initial energy from 12.5 to 18 keV thus ensuring sensitivity to fluctuations of WIMPs with masses up to 1 TeV [29].…”

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.
