Abstract

The Argo-YBJ experiment has now reached its final design configuration. The detector system consists of a full coverage array (about 5800 square meters) of Resistive Plate Chambers (RPCs). The throughput depends on the trigger rate and threshold. The DAQ system must be able to sustain a maximum transfer rate of the order of 15 MB/s and a high peak data flow. Data are read out using a typical front-end acquisition chain built around a custom bus. Specialized electronics have been designed and dedicated software has been written to perform this task. Data are sent to the online farm through a switch exploiting a gigabit ethernet protocol. A solution to transfer data from the YBJ laboratory to the laboratories belonging to the Argo-YBJ collaboration exploiting the GRID middleware has also been implemented. In this paper we describe the daq and the data mover main characteristics and performance. Index Terms--Data acquisition, data mover, GRID, RPC.

The attenuation and absorption lengths have been determined by applying different analysis methods. Furthermore the proton-air inelastic cross section around few hundrend TeV is explored by using the factor $k=\lambda_{abs}^{sim}/\lambda_{pair}^{sim}$

Abstract

The ARGO-YBJ detector is an Extensive Air Shower (EAS) array located in Tibet (P.R. China) at 4300 m a.s.l., performing a continuos sky observation by shower reconstruction with an energy threshold of a few hundreds of GeV. To lower this threshold to E~1GeV the detector has been designed to work in scaler mode, i.e. recording the counting rate of each module of the detector at fixed time intervals. At these energies, signals due to local (e.g. solar events) and cosmological (e.g. Gamma Ray Bursts, GRBs) phenomena are expected as a significant enhancement of the counting rate over the background. Results of the search for the GRBs in coincidence with satellite detections are presented.

Abstract

The ARGO-YBJ experiment at the Yangbajing Laboratory (4300 m a.s.l.) is taking data with about 1900 m2 of its carpet. The digital read-out of the RPCs, performed by means of pick-up electrodes 7 x 62 cm2 ('strips'), well suited to detect small size air showers, implies a limitation to the measurable energy of a few hundreds of TeV. In order to extend the energy range up to the knee region an analog read-out of the RPCs has been implemented. Each RPC has been equipped with two large size pads of dimensions 1.40 x 1.25 m2. The analog read-out system has been put in operation on 180 m2 of the detector, allowing a cross-check of digital and analog information. In this paper a brief description of the analog read-out system is given, and preliminary results are discussed.

Abstract

The ARGO-YBJ experiment is planned to detect gamma ray sources with an energy threshold of a few hundreds of GeV. The large field of view of the detector and its high duty cycle allow the continuous monitoring of a large part of the sky, searching for both unknown stable sources and transient emissions as AGN flares and Gamma Ray Bursts. In this work we present the first data obtained with a subset of the detector (covering _ 1900 m_ ) concerning the search for stable and transient sources in the declination range _
