    Electron-muon identification by atmospheric shower in a new concept of an EAS detector
    (Elsevier Science Bv, 2012) Iori, M.; Arslan, E.; Denizli, Haluk; Kaya, M.; Yılmaz, Ali; Russ, James
    We show the test results for TOF resolution and mu/e separation capabilities of a prototype element (Iori and Sergi, 2008 [1]), intended for deployment in an array capable of measuring large zenith angle cosmic rays as well as detecting the signature of Ultra High Energy tau neutrino interactions using the Earth skimming strategy (Fargion et al., 2004 [2], Feng et al., 2002 [3], Beacom et al., 2003 [4], Zas, 2005 [5]). The module was designed to recognize single particles and determine the direction of motion (up/down) and measure the trajectory angles. It uses two pairs of scintillator counters, named towers, each composed by two tiles (20 x 20 cm(2), 1.4 cm thick), separated by 160 cm. Each tile is read by one low voltage R5783 Hamamatsu photomultiplier (PMT). Two PMT boxes are attached to a metal structure that defines the axis of the array. Each tile is embedded in a PVC box which also contains the PMT. The PMT has excellent time resolution (approximate to 400 ps) for good TOE precision. The PMT signal was digitized by the MATAQ board in coincidence with KASCADE-GRANDE (KG) shower Delagnes and Breton, 2001 [6]. (C) 2012 Published by Elsevier B.V.

    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)
