We present the all-particle primary cosmic ray energy spectrum obtained by a
parametric event-by-event determination of the primary energy. The results are
obtained on the basis of an expanded experimental data from the GAMMA
experiment. The method was developed using the CORSIKA EAS simulation
code with the SYBILL interaction model and taking into account the response of
the GAMMA detec

LOPES is one the pioneering experiments for the measurement of radio emission
from air showers with digital radio receivers. It is set up at the site of the
KASCADE-Grande air shower array and takes data in conjunction with it. This
gives us the unique possibility to combine LOPES and KASCADE-Grande data.
In its second phase LOPES has been extended to 30 antennas, which increases

Cosmic ray showers that trigger the IceTop surface array generate high energy muons
that are measured by the IceCube in-ice detector. The large surface and underground
area of this 3-dimensional instrument at completion guaranties significant statistics
for shower energy up to about 1 EeV. Since the number of muons is sensitive to the
type of the primary cosmic ray nucleus these events can be

The dependence of the intensity of muon bundles detected at the Earth's surface by
means of the coordinate-tracking detector DECOR on the angle between muon arrival
direction and geomagnetic field vector (pitch angle) has been analysed. It is found
that muon bundle intensity decreases with the increase of the transverse component of
the magnetic field in comparison with calculations performed

LOPES30 is a digital radio antenna array working in the frequency range 40 -- 80 MHz
with 30 dipole antennas triggered by the air shower experiment KASCADE-Grande. From
an absolute calibration the measured field strength of the LOPES30 antenna system is
known and the invesitigation of a large data set taken in east-west polarisation is
performed.
The reconstructed pulse height of the radio em

A large area streamer tube detector (128m^2), located within the KASCADE-
Grande Experiment, has been built with the aim to identify muons
(E>0.8GeV) and their direction in extensive air showers. Besides the
investigation of the muon pseudorapitity in EAS, the application of the
tracking detector in reconstructing the muon production height is
evaluated. The combination of the muon production

A new approach to investigations of ultra-high energy cosmic rays based on the new
EAS observable - spectra of local density of muons measured at ground level in a wide
range of zenith angles - is considered. It is shown that muon density spectra are
sensitive to the primary cosmic ray spectrum and composition, and to features of the
forward kinematic region of hadronic interaction, and thus p

ARGO-YBJ is a "full coverage" air shower detector consisting of
a carpet of Resistive Plate Chambers, located at Yangbajing (4300m a.s.l.).
Using the data collected by the central detector (5800m^2 area)
the cosmic ray shadowing effect due to the Moon is studied.
The comparison of experimental results with Montecarlo simulations is
also discussed.

The KASCADE-Grande experiment, located at the area of the Forschungszentrum
Karlsruhe, Germany, measures extensive air showers in the energy range between
10^{14} and 10^{18} eV, thus covering the first and the second knee of cosmic rays.
Former analyses of electron and muon data of the original KASCADE experiment revealed
knee-like features in the energy spectra of light elements causing th

ARGO-YBJ is a full coverage Extensive Air Shower array located by the
high-altitude cosmic rays laboratory of Yangbajing (4300 m a.s.l., Tibet,
China). The detector consists of a layer of Resistive Plate Counters covering an area of
about 5800 m^2 with 58x62 cm^2 unit cells. This design allows a detailed
characterization of cosmic ray showers induced by primaries with energy in the range

We present an updated all-particle energy spectrum using data set collected in the
period from 2000 November through 2004 October by Tibet-III air-shower array. The
energy determination of the air showers is made by fitting the lateral density
distribution of the shower particles to the modified NKG function which is optimized
by simulation calculation using interaction models of QGSJET01c

Using the data taken by the ARGO-YBJ experiment (606 $g/cm^{2}$, Tibet, P.R.China)
in the period of July to September 2006, the first measurement of
EAS size spectrum in the range of $N_{e}=5\times10^{4}-5\times10^{6}$
is presented at different zenith angles. The attenuation and absorption
lengths have been determined by applying different analysis methods.
Furthermore the proton-air inelasti

The air shower size (Ne) spectrum of cosmic rays around the knee at different zenith
angles has been studied with the Tibet-III air-shower array. The air shower size is
estimated by fitting the lateral density distribution of the shower particles using
the modified NKG function, which is optimized by the Monte Carlo simulation by using
interaction models of QGSJET01c and SIBYLL2.1 taking into
