The Tibet hybrid air shower experiment is composed by an air-shower core
detector array and the air-shower array (and a large muon detector from October, 2010), that has been operated at Yangbajing (4300 m above sea level) in Tibet, China, since 1996. This multi-detector system is used for the search for high energy celestial gamma-ray and cosmic ray sources, and for the study of the...

The GRAPES-3 experiment is a high density array of 400 plastic scintillator detectors and a large (560 sq.m.) area muon detector located at Ooty at an altitude of 2200 m above sea level. The primary objective of this experiment is to study the high energy processes occurring in the universe through a systematic study of composition of primary cosmic rays below and above the `knee', compact...

Status of the GAMMA experiment is presented. The all-particle energy spectrum of the primary cosmic rays at energies 1 – 300 PeV has been obtained on the basis of the GAMMA experimental improved data. The irregularities of the energy spectrum above the knee are discussed in comparison with other experiments. An upper limit of Galactic diffuse gamma ray flux measured with the GAMMA experiment...

IceTop air shower array, as the surface component of the IceCube Neutrino
Observatory at the South Pole, is now 92% complete and taking data with 73
stations. The detector will study the mass composition of primary cosmic rays
from the knee up to about 1 EeV. In this talk the performance of IceTop,
and the preliminary results in the energy range of 1 PeV to 80 PeV will
be reported.

The study of the cosmic ray energy spectrum in the interval 10^16 eV - 10^18 eV
results of particular importance for several reasons, one of them is the possible
existence of a second knee, other one is the possible presence of a galactic-extragalactic
transition in the cosmic ray flux and another one is the prediction from some
astrophysical models of a...

The Muon Tracking Detector (MTD) in KASCADE-Grande experiment measures with
high accuracy muon directions in EAS (Emu>800MeV). In addition, shower
directions are determined by the surface detectors with high precision. These
two conditions allow to study shower longitudinal development by means of
quantities like muon production heights and muon pseudorapidities and
lateral distributions...

We review the different definitions of the age parameter used in the lateral and longitudinal electron distributions. In order to remove ambiguities in the interpretation of the experimental data, we have compared simulations with CORSIKA carried simultaneously with the options NKG and EGS.
The effect of the positron annihilation cross section missing in the NKG approach is pointed out for...
