Gathering Data

The ARGO-YBJ experiment has been gathering data steadily since November 2007 at the YangBaJing Cosmic Ray Laboratory (Tibet, P.R. China, 4300m a.s.l., 606 g/cm2). ARGO-YBJ is confronting various open problems in Cosmic Ray (CR) physics. The search for CR sources is carried out by observing TeV gamma-ray sources, both galactic and extra-galactic. The CR spectrum, composition and anisotropy are measured in a wide energy range (TeV ÷ PeV), thus overlapping direct measurements for the first time. This paper summarizes the current status of the experiment and describes some of the scientific highlights since 2007.

PAMELA is a satellite borne experiment designed to study with great accuracy cosmic rays of galactic, solar, and trapped nature in a wide energy range (protons: 80 MeV–700 GeV, electrons 50 MeV–400 GeV). Main objective is the study of the antimatter component: antiprotons (80 MeV–190 GeV), positrons (50 MeV–270 GeV) and search for antimatter with a precision of the order of 10-8). The experiment, housed on board the Russian Resurs-DK1 satellite, was launched on June, 15 2006 in a 350 × 600 km orbit with an inclination of 70 degrees. The detector is composed of a series of scintillator counters arranged at the extremities of a permanent magnet spectrometer to provide charge, Time-of-Flight and rigidity information. Lepton/hadron identification is performed by a Silicon-Tungsten calorimeter and a Neutron detector placed at the bottom of the device. An Anticounter system is used offline to reject false triggers coming from the satellite. In self-trigger mode the Calorimeter, the neutron detector and a shower tail catcher are capable of an independent measure of the lepton component up to 2 TeV. In this work we present some of its scientific results in its first five years of operation.

Preliminary results of muon bundle studies in of zenith angle range θ ≥ 60° and multiplicities by means of coordinate detector DECOR are discussed. Estimates of muon bundle characteristics at large zenith angles obtained with CORSIKA code demonstrate the ability of such not large detector as NEVOD-DECOR complex to perform cosmic ray studies in a very wide energy range from 1011 eV to more than 1017 eV.

The ARGO-YBJ experiment has been in stable data taking for more than 5 years at the YangBaJing Cosmic Ray Observatory (Tibet, P. R. China, 4300 m a.s.l., 606 g/cm2). With a duty-cycle greater than 86%, the detector collected about 5 × 1011 events in a wide energy range, from few hundred GeV up to about 10 PeV. High altitude location and detector features make ARGO-YBJ capable of investigating a wide range of important issues in Cosmic Ray and Astroparticle Physics by imaging the front of atmospheric showers with unprecedented resolution and detail. In this paper, the main physics results in gamma-ray astronomy and in cosmic ray physics are summarized.

The ARGO-YBJ experiment has been in stable data taking for 5 years at the YangBaJing Cosmic Ray Laboratory (Tibet, P.R. China, 4300 m a.s.l., 606 g/cm<sup>2</sup>). With a duty-cycle greater than 86% the detector collected about 510<sup>11</sup> events in a wide energy range, from few hundreds GeV up to the PeV. A number of open problems in cosmic ray physics has been faced exploiting dierent analyses. In this paper we summarize the last results in gamma-ray astronomy and in the cosmic ray physics and introduce the LHAASO project, mainly driven by the Chinese community, to study the cosmic ray physics up to 10<sup>17</sup> eV.
