Future Extensive Air Shower arrays: from Gamma-Ray Astronomy to Cosmic Rays
Despite large progresses in building new detectors and in the analysis
techniques, the key questions concerning the origin, acceleration and
propagation of Galactic Cosmic Rays are still open. A number of new EAS arrays
is in progress. The most ambitious and sensitive project between them is
LHAASO, a new generation multi-component experiment to be installed at very
high altitude in China (Daocheng, Sichuan province, 4400 m a.s.l.). The
experiment will face the open problems through a combined study of photon- and
charged particle-induced extensive air showers in the wide energy range
10 - 10 eV. In this paper the status of the experiment will be
summarized, the science program presented and the outlook discussed in
comparison with leading new projects.Comment: Invited plenary talk at RICAP 201
ARGO-YBJ: Highlights and Prospects
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/cm2). With a duty-cycle greater than 86% the detector collected about 51011 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 1017 eV
Simulation of the Cosmic Ray Moon Shadow in the Geomagnetic field
An accurate MonteCarlo simulation of the deficit of primary cosmic rays in
the direction of the Moon has been developed to interpret the observations
reported in the TeV energy region until now. Primary particles are propagated
trough the geomagnetic field in the Earth-Moon system. The algorithm is
described and the contributions of the detector resolution and of the
geomagnetic field are disentangled.Comment: 4 pages, 5 figures, Contribution to the 31st ICRC, Lodz, Poland, July
