A coordinate-tracking setup based on drift chambers for investigating ultrahigh energy cosmic rays

Abstract

A large-scale coordinate-tracking setup for registering the near-horizontal muon flux from ultrahigh energy cosmic rays is under development at the MEPhI. The setup is based on drift chambers from the neutrino detector at the Institute of High Energy Physics’ U-70 accelerator, which have a large sensitive area (1.85 m2) and good angular and spatial resolution with a relatively low number of measuring channels.
