Emulsion detector for future experiment SHiP at CERN

Abstract

The new general-purpose fixed target experiment SHiP (Search for Hidden Particles) at the CERN SPS (Super Proton Synchrotron) is aimed at research in the field of Beyond Standard Model (BSM) physics and of tau-neutrino physics. The Emulsion Neutrino Detector will be one of the main elements in the SHiP detector design. It is intended for search for Dark Matter scattering on electrons of nuclear emulsion and for tau-neutrino and anti tau-neutrino direct observation, and study their properties and the cross section. The main source of both hidden particle and tau-neutrino event fluxes is the decay of charmed particles produced in the SHiP proton target. The detection of the production and decay of charmed hadrons in the target will be performed through nuclear emulsion films employed in the Emulsion Cloud Chamber target structure. The paper describes the basic principles of the SHiP neutrino emulsion detector and some measures for its optimization.
