The LHAASO experiment: From Gamma-Ray Astronomy to Cosmic Rays

LHAASO is expected to be the most sensitive project to face the open problems in Galactic cosmic ray physics through a combined study of photon- and charged particle-induced extensive air showers in the energy range 1011 - 1018 eV. This new generation multi-component experiment will be able of continuously surveying the TeV sky for steady and transient sources from 100 GeV to 1 PeV, thus opening for the first time the PeV range to the direct observations of the high energy cosmic ray sources. In addition, the different observables (electronic, muonic and Cherenkov/fluorescence components) that will be measured in LHAASO will allow to investigate origin, acceleration and propagation of the radiation through a measurement of energy spectrum, elemental composition and anisotropy with unprecedented resolution. The installation of experiment started at very high altitude in China (Daocheng site, Sichuan province, 4410 m a.s.l.). The commissioning of the first quarter of the layout is expected in 2018. The conclusion of installation in 2021.
