Techniques for Radio Detection of Ultra-High Energy Cosmic Rays

IEEE Transactions on Nuclear Science, 2009
Radio signals emitted from cosmic ray air showers can be used as a new technique for the detection of ultra-high energetic cosmic rays or neutrinos at energies above 1018 eV. To apply this technique for the detection of air showers, cost effective new antennas and on-line self-trigger systems have to be developed.

Applications of ancient cosmic-ray exposures: Theory, techniques and limitations

Quaternary Geochronology, 2006
This study is a review of terrestrial cosmogenic nuclides (TCN) applications based on the specific circumstance of ancient exposure records, i.e. formations that have been exposed in the past before being rapidly and completely shielded by burial.

Cosmic ray exposure ages of tektites by the fission-track technique

Journal of Geophysical Research, 1965
Tektites exposed to primary cosmic radiation will contain distinctive, readily identifiable, induced-fission tracks, a large fraction of which will survive the heating which occurs as tektites fall to earth. A search for such events in samples from each of the four chronological tektite groups failed to reveal such events and thereby indicates an ...

PROSPECTS FOR THE DETECTION OF HIGH-ENERGY COSMIC RAYS USING RADIO TECHNIQUES

Exotic Nuclei and Nuclear/Particle Astrophysics, 2006
The determination of the origin of cosmic events with energy beyond 10(18) eV remains a challenge in cosmic-ray physics, To determine the nature of these particles, their origin, and the way they are being accelerated, requires new efforts where radio detection will play a crucial role. Recently, the LOPES collaboration employed techniques based on the

Simple technique for determining the mean lifetime of the cosmic ray μ meson

American Journal of Physics, 1978
A single scintillation counter is used for determining the lifetime of cosmic ray μ mesons. The experimental arrangement has a greater detection rate and a higher detection efficiency than the conventional multidetector delayed coincidence technique.

Comments on the Workshop on techniques to study Cosmic Rays with E>1019eV

Nuclear Physics B - Proceedings Supplements, 1992
Abstract Jim Cronin asked me and other colleagues to attend this Workshop to provide a critical point of view from non-expert scientists on the future developments needed to study Cosmic Rays at the highest energy. Being from outside this field, most of my comments will therefore be quite naive.

Status of the radio technique for cosmic-ray induced air showers

Nuclear and Particle Physics Proceedings, 2016
Abstract Radio measurements yield calorimetric information on the electromagnetic shower component around the clock. However, until recently it was not clear whether radio measurements can compete in accuracy with established night-time techniques like air-Cherenkov or air-fluorescence detection.

An investigation of techniques for the measurement and interpretation of cosmic ray isotopic abundances

1978
An instrument, the Caltech High Energy Isotope Spectrometer Telescope (HEIST), has been developed to measure isotopic abundances of cosmic ray nuclei in the charge range 3 ≤ Z ≤ 28 and the energy range between 30 and 800 MeV/nuc by employing an energy loss -- residual energy technique.

Markov stochastic technique to determine galactic cosmic ray sources distribution

Journal of Astrophysics and Astronomy, 2010
A new numerical model of particle propagation in the Galaxy has been developed, which allows the study of cosmic-ray production and propagation in 2D. The model has been used to solve cosmic ray diffusive transport equation with a complete network of nuclear interactions using the time backward Markov stochastic process by tracing the particles ...
