Electron muon identification by atmospheric shower and electron beam in a new concept of an EAS detector

TL;DR

This paper introduces a novel EAS detector concept capable of distinguishing electrons from muons with high time resolution, suitable for large-area cosmic ray measurements and neutrino detection at ultra-high energies.

Contribution

The paper presents a new EAS detector design with enhanced particle identification and timing capabilities, tested through coincidence measurements with existing experiments.

Findings

Effective mu/e separation demonstrated

High time resolution achieved

Potential for large-scale ultra-high-energy cosmic ray detection

Abstract

We present results demonstrating the time resolution and $\mu$/e separation capabilities with a new concept of an EAS detector capable for measurements of cosmic rays arriving with large zenith angles. This kind of detector has been designed to be a part of a large area (several square kilometers) surface array designed to measure Ultra High Energy (10-200 PeV) $\tau$ neutrinos using the Earth-skimming technique. A criteria 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.
