    Electron-muon identification by atmospheric shower and electron beam in a new eas detector concept
    (IOP Publishing Ltd., 2015) İori, Maurizio; Denizli, Haluk; Yılmaz, Ali; Ferrarotto, Fabio; Russ, James
    We present results demonstrating the time resolution and mu/e separation capabilities of a new concept. for an EAS detector capable of measuring cosmic rays arriving with large zenith angles. This kind of detector has been designed to be part of a large area (several square kilometer) surface array designed to measure ultra high energy (10-200 PeV) tau neutrinos using the Earth-skimming technique. A criterion to identify electron-gammas is also shown and the particle identification capability is tested by measurements in coincidence with the KASKADE-GRANDE experiment in Karlsruhe, Germany.

    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.
