Published online: 4 August 2015
The ARGO-YBJ experiment is an Extensive Air Shower array that has been operated at the high altitude Yangbajing Cosmic Ray Laboratory (Tibet, P.R. China 4300 m a.s.l.) in its final configuration since December 2007 until February 2013. The detector consists of a dense layer of Resistive Plate Counters (RPCs) covering an area of about 11000 m2. It has been designed to measure the temporal and spatial structure of Extensive Air Showers (EAS) with high space-time resolution. The detector gives a quite highly detailed picture of shower footprints at ground. It is perfectly suitable to understand the EAS morphology. These detector characteristics have been used for seeking particles of large rest mass produced in cosmic rays by measuring the Multiple Shell Shower Fronts relative delays. The technique and preliminary results will be illustrated in the present work.
