Abstract

The setting up of the ARGO detector at the YangBaJing Cosmic Ray Laboratory (4300ma.s.l., Tibet, P.R. China) has been completed during the last spring (2007). It consists of a central carpet made of 130 identical sub-units of 12 RPCs each (a ‘‘cluster’’), covering a surface of about 5800m2 with 93% active area, and a guard ring of 24 further clusters of the same type surrounding the centralcarpet with a lower sampling density. Signals are picked up by external electrodes of small size, thus allowing the sampling of EAS with high space-time granularity. Shower events are detected at a trigger rate of about 4 kHz. Events with a few particles detected by a singlecluster are counted in scaler mode on a time base of 500 ms. The intrinsic modularity of the ARGO detector allowed us to collect data even during the setting-up period, using only the central carpet (or even part of it). Some preliminary results from the analysis of events collected in a few months of data taking are presented.
