Description

A new detection system performing coincidence measurements by a calorimeter (WILLI) and a small array of 12 scintillator stations has been installed in NIPNE-HH, Bucharest, Romania. The aim of the system is to investigate the muon charge ratio within extensive air-showers by using the mini-array as trigger for the time sensitive WILLI calorimeter, which is able to reconstruct the muon charge ratio by the different decay times of positive and negative muons. Such experimental studies could provide detailed information on the primary cosmic ray composition at energies around 10^15 eV. Simulation studies and first experimental tests, regarding the performances of the mini-array, as well as the sensitivity to differences in various hadronic interaction models have been performed.
