Highlights from the Telescope Array

EPJ Web of Conferences, 2016
The Telescope Array measures the properties of ultra high energy cosmic ray induced extensive air showers. We do this using a variety of techniques including an array of scintillator detectors to sample the footprint of the air shower when it reaches the

Cosmic coding and transfer for ultra high security near-field communications

iScience, 2023
Summary: By using true random number (TRN) generators, encoding with the highest security can be realized. However, a completely secure strategy to transfer these TRNs has not yet been devised.

DEVELOPMENT OF THE COSMIC RAY TECHNIQUES

Le Journal de Physique Colloques, 1982
A close relationship exists between the advances of cosmic-ray physics and technical developments. Thus the development of highly sensitive ionization chambers, eventually to become self-recording instruments, was an essential prerequisite of the observations which first suggested, then proved the extraterrestrial origin of the radiation. The invention

Measurement of the flux of ultra high energy cosmic rays by the stereo technique

Astroparticle Physics, 2009
The High Resolution Fly's Eye experiment has measured the flux of ultrahigh energy cosmic rays using the stereoscopic air fluorescence technique. The HiRes experiment consists of two detectors that observe cosmic ray showers via the fluorescence light they emit. HiRes data can be analyzed in monocular mode, where each detector is treated separately, or

Cosmic ray proton spectrum determined with the imaging atmospheric Cherenkov technique

Physical Review D, 1999
The HEGRA system of 4 Imaging Atmospheric Cherenkov Telescopes (IACTs) has been used to determine the flux and the spectrum of cosmic ray protons over a limited energy range around 1.5 TeV. Although the IACT system is designed for the detection of gamma-rays with energies above 500 GeV, it has also a large detection area of $ \simeq 10^6 m^2 \cdot 3 ...

A novel technique to detect special nuclear material using cosmic rays [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2012
Abstract. Resistive plate chambers (RPCs) are widely used in high energy physics for both tracking and triggering purposes, due to their excellent time resolution, rate capability, and good spatial resolution. RPCs can be produced cost-effectively on large scales, are of rugged build, and have excellent detection efficiency for charged particles.
