“…A different longitudinal development of the shower could stretch or compress the energy scale in such a way as to affect the spectral shape. In this context it is worthwhile to note that the proton-air inelastic cross section measured by the ARGO-YBJ experiment in the energy range ð1 Ä 100Þ TeV [37] has been found in good agreement with the values set in the CORSIKA/QGSJET code. According to the results shown in Fig.…”

The relation between the measured strip multiplicity and the primary energy distribution has been studied in [37] and has been found to be in good agreement with Monte Carlo predictions. The reliability of the simulation procedure has been checked by comparing the distributions of several variables obtained applying the same selection cuts to data and to Monte Carlo events.…”

The ARGO-YBJ experiment detects extensive air showers in a wide energy range by means of a full-coverage detector which is in stable data taking in its full configuration since November 2007 at the YBJ International Cosmic Ray Observatory (4300 m a.s.l., Tibet, People's Republic of China). In this paper the measurement of the light-component spectrum of primary cosmic rays in the energy region * Corresponding author. mari@fis.uniroma3.it PHYSICAL REVIEW D 85, 092005 (2012) 1550-7998= 2012=85(9)=092005 (10) 092005-1 Ó 2012 American Physical Society ð5 Ä 200Þ TeV is reported. The method exploited to analyze the experimental data is based on a Bayesian procedure. The measured intensities of the light component are consistent with the recent CREAM results and higher than that obtained adding the proton and helium spectra reported by the RUNJOB experiment.

“…The figure 5(a) reports the measurement of the total p-p cross section as measured by ARGO-YBJ [5]. The result dates back to 2009 and is obtained by exploiting the cosmic ray intensity attenuation observed with increasing angle between the arrival direction of primary cosmic rays and the zenith.…”

The ARGO-YBJ experiment consists of a 5000 m 2 single layer of Resistive Plate Chambers situated at Yangbajing, Tibet (P.R. of China), 4300 meters a.s.l. (atmospheric depth 600 g/cm 2 ). The percentage of active area all over the carpet is 92% and a partially instrumented guard ring (1700 m 2 ) around the central zone extends the instrumented area up to 11000 m 2 . The experiment is operated in scaler mode, shower mode and analog mode and is sensitive to cosmic rays in the 10 9 -10 15 eV energy range. From few hundreds GeV on, the arrival direction of cosmic rays is inferred by the study of the induced extensive air showers. A review of the most important results of the ARGO-YBJ experiment in gamma-ray astronomy and cosmic-ray physics will be given, focusing on the potential of RPCs in ground-based astroparticle physics.

“…The figure shows the performance of the analog RPC readout: the study of the core region of high energy showers can reach an unprecedented richness of details. Owing to the analog readout, the measurement of the proton-air cross section [10] and the composition studies [5] will be extended to PeV energies.…”

“…zenith angles, and exploiting the high detector accuracy in reconstructing the shower properties at ground, ARGO-YBJ has measured the production cross section between 1 -100 TeV CR protons and Air nuclei [10]. The analysis results have been also used to estimate the total protonproton cross section at center-of-mass energies between 70 and 500 GeV.…”

The ARGO-YBJ experiment has been in stable data taking from November 2007 till February 2013 at the YangBaJing Cosmic Ray Observatory (4300 m a.s.l.). The detector consists of a single layer of Resistive Plate Chambers (RPCs) (6700 m 2 ) operated in streamer mode. The signal pick-up is obtained by means of strips facing one side of the gas volume. The digital readout of 1 arXiv:1504.01510v1 [astro-ph.IM] 7 Apr 2015 the signals, while allows a high space-time resolution in the shower front reconstruction, limits the measurable energy to a few hundred TeV. In order to fully investigate the 1-10 PeV region, an analog readout has been implemented by instrumenting each RPC with two large size electrodes facing the other side of the gas volume. Since December 2009 the RPC charge readout has been in operation on the entire central carpet (∼ 5800 m 2 ). In this configuration the detector is able to measure the particle density at the core position where it ranges from tens to many thousands of particles per m 2 . Thus ARGO-YBJ provides a highly detailed image of the charge component at the core of air showers. In this paper we describe the analog readout of RPCs in ARGO-YBJ and discuss both the performance of the system and the physical impact on the EAS measurements.
