TLDR
In this paper, the authors used an optical detection system at Volcano Ranch Station near Albuquerque, New Mexico, to estimate the number of charged particles in air-shower trajectories and sizes.Abstract:
Extensive air-shower trajectories and sizes (numbers of charged particles) have been measured using an optical detection system at Volcano Ranch Station near Albuquerque, New Mexico. Light produced by atomospheric scintillation and Cherenkov emission by shower particles was measured at distances of 0.7 to approx. 10 km. The shower sizes determined by the optical measurements are in satisfactory agreement (an average of 10% higher) with measurements by the ground-level scintillation-counter array at Volcano Ranch.read more

Cosmic rays and particle physics.
TL;DR: In this paper, the authors present a model for accelerating a particle to >100 TeV using cosmic rays and neutrino-induced muons, which they call cosmic ray showers.

Measurements of the Cosmic Ray Composition with Air Shower Experiments
Karl-Heinz Kampert,Michael Unger +1 more
TL;DR: In this article, a review of air shower data related to the mass composition of cosmic rays above 10 15 eV is presented, and the analysis of these experimental results in terms of primary mass is highly susceptible to the theoretical uncertainties of hadronic interactions in air showers.

Ultrahigh energy cosmic rays
A. Letessier-Selvon,Todor Stanev +1 more
TL;DR: A review of the most recent results from the investigation of the ultrahigh energy cosmic rays, particles of energy exceeding 10 − 18 eV, is given in this article. But the results of these two experiments are limited to two experiments, the High Resolution Fly's Eye and the Southern Auger Observatory.

Astrophysical origins of ultrahigh energy cosmic rays
TL;DR: In this article, the authors discuss the basic observational features at the end of the cosmic ray (CR) energy spectrum, and present the main characteristics of each of the experiments involved in the detection of these particles.

Ultrahigh energy cosmic rays: the state of the art before the auger observatory
TL;DR: In this paper, the authors discuss the important progress made in recent years towards understanding the experimental data on cosmic rays with energies ≳ 1019 eV and discuss the potential of future cosmic ray experiments for the discovery of tiny black holes that should be produced in the earth's atmosphere if TeV-scale gravity is realized in Nature.
