ARGO-YBJ

Attività

ARGO-YBJ is a detector of small air showers, located at the Cosmic Ray Laboratory of Yangbajing, in Tibet, at an altitude of 4300 meters, about 90 Km north of Lhasa.

It consists of a single layer of Resistive Plane Counters  (RPCs) of area 6500 m2,  providing a detailed space-time picture of the shower front.

Thanks to the full coverage and the extreme altitude, ARGO-YBJ can work with an energy threshold much lower than "classical" sampling air shower arrays.

It uses two independent data acquisition techniques, operating in different energy ranges: 

  • Detection of showers with a number of particles N > 20, to study primary gamma rays and cosmic rays of energy E >300 GeV.
  • Single particle counting, to study transient phenomena of energy E > 10 GeV.

 

 

Attività di ricerca: 

ARGO-YBJ is devoted to study astrophysical gamma ray sources and cosmic rays. Its main fields of research are:

  • Gamma ray astronomy at energy E > 300 GeV: study of galactic sources (Supernova remnants, plerions, pulsars, diffuse emission from the galactic plane) and extragalactic sources (Active Galactic Nuclei)
  • Gamma Ray Bursts at energy > 10 GeV
  • Spectrum of cosmic rays at energy E > 1 TeV
  • Measurement of the ratio of proton-antiproton in cosmic rays using the Moon shadow 
  • Sun and heliosphere physics

The Torino group is mainly involved in the search for gamma ray sources and Gamma Ray Bursts.
