    SiPM application for a detector for UHE neutrinos tested at Sphinx station
    (Elsevier Science Bv, 2014) Iori, Maurizio; Atakişi, İsmail Okan; Chiodi, Giacomo; Denizli, Haluk; Ferrarotto, Fabia; Yılmaz, Ali
    We present the preliminary test results of the prototype detector, working at Sphinx Observatory Center, Jungfraujoch (similar to 3800 m a.s.l.) HFSJG - Switzerland. This prototype detector is designed to measure large zenith angle showers produced by high energy neutrino interactions in the Earth crust. This station provides us an opportunity to understand if the prototype detector works safely (or not) under hard environmental conditions (the air temperature changes between -25 degrees C and -5 degrees C). The detector prototype is using silicon photomultiplier (SiPM) produced by SensL and DRS4 chip as read-out part. Measurements at different temperature at fixed bias voltage (similar to 29.5 V) were performed to reconstruct tracks by Time Of Flight. (C) 2014 Elsevier B.V. All rights reserved.

    Tests for a new concept of EAS detector for UHE neutrinos
    (Iop Publishing Ltd, 2013) Iori, Maurizio; Arslan, E.; Denizli, Haluk; Ferrarotto, Fabio; Kaya, Mithat; Yılmaz, Ali
    We present results from tests performed at Karlsruhe Institute of Technology (KIT) and at FermiLab Meson Test Beam Facility (FNAL) to study electron-muon separation, time of flight resolution and the acceptance for a new EAS detector concept. The very good time resolution and adjustable orientation of the detector permit to separate upward-moving tracks from downward tracks at any orientation with high efficiency. With these performances the detector can measure interaction products from cosmic neutrinos with zenith angles > 90 degrees, defining a chord through the earth as the interaction path. This kind of detector using SiPM will be a part of a large area array (several square kilometer) designed to measure UHE neutrinos (0.01-100 EeV)
