Gamma astronomy with the ARGO-YBJ experiment
Very High Energy (VHE) g -astronomy and cosmic ray physics are the main goals of the ARGOYBJ
experiment. The detector is located in Tibet (People's Republic of China) and is a full
coverage Extensive Air Shower array consisting of a carpet of Resistive Plate Chambers (RPCs).
Altitude and full coverage ensure an energy threshold of few hundreds of GeV for primary photons
detected in shower mode, while the RPC time resolution gives a good pointing accuracy, thus
allowing a high sensitivity to g -ray sources. The large eld of view (FoV) and the high duty-cycle
allow the continuous monitor of the Northern sky in the declination band (10, +70). The
detector operates also in scaler mode in order to look for Gamma Ray Burst (GRB) signals in the
range 1-100 GeV in coincidence with GRB detection by satellites. After some detail about the
performances of the detector, the present results concerning g -astronomy will be presented
Astroparticle Physics with ARGO-YBJ experiment
The ARGO-YBJ experiment, installed at the Yangbajing Cosmic Ray Laboratory (Tibet,
China), at 4300 m a.s.l., is a detector 100x110m2 large, made by a layer of Resistive Plate
Counters (RPCs) consisting of a central carpet with almost full coverage extending over an area
of about 5.500 m2, surrounded by a guard ring with partial coverage. The high space-time
granularity, the full-coverage technique and the high altitude location make this detector a
unique device for a detailed study of the atmospheric shower characteristics with an energy
threshold of a few hundred GeV. These properties in addition to the large field of view and the
high duty cycle enable the ARGO-YBJ experiment to monitor the sky in a continuous way.
Results have been reached in a wide variety of fields ranging from Gamma Astronomy, to Solar
Physics, from Cosmic Rays composition to hadronic interactions and proton-antiproton ratio. A
summary of all these results will be presented and reviewed
