Abstract:
The WILLI-AIR (Weal Ionization Lead Lepton Interaction for Air-shower Investigations in Romania) experiment is developed to investigate charged particle resulted in interaction of cosmic rays with the nuclei in the atmosphere. The focus is in the low energy region of the spectrum, up to 10^15eV, for the incident particle. The experiment is measuring the muon flux and the muon charge ratio for a single extended air shower using the method of delayed coincidence. The detection system contain a number of 48 individual detectors and one electromagnetic calorimeter with 20 layers. Each stations will contain two pices of plastic scintillator, each read-out individually by one photo-multiplier. The surface of the experiment is correlated with the energy of the primary particle and covers around 300 square meters, with a constant pitch between the detectors. Together the counters from the mini-array are providing the information about extended air shower arrival at the ground level. Using the muons that are decaying inside the electromagnetic calorimeter the charge ratio is determined.
