Properties of Heavy Secondary Fluorine Cosmic Rays: Results from the Alpha Magnetic Spectrometer

Physical Review Letters, 2021
Precise knowledge of the charge and rigidity dependence of the secondary cosmic ray fluxes and the secondary to primary flux ratios is essential in the understanding of cosmic ray propagation.

Investigation of cosmic rays and their secondaries at aircraft altitudes

Radiation Measurements, 2001
A very extensive study of the radiation field at aircraft altitudes has been carried out over the last few years. These investigations formed part of a European wide collaboration involving several laboratories with extensive experience in cosmic ray research and/or dosimetry.

Secondary Cosmic Rays

2020
For the purpose of astroparticle physics the influence of the Sun’s and the Earth’s magnetic field is a perturbation, which complicates a search for the sources of cosmic rays. The solar activity produces an additional magnetic field, which prevents part of galactic cosmic rays from reaching Earth.

Absorption of Cosmic-Ray Secondaries and Showers

Physical Review, 1936
A triple Geiger-M\"uller counter system has been used with the three counters in a vertical line to measure the absorption by lead of single secondary and shower rays produced in lead and emerging in a small solid angle including the vertical. The precision in the estimate of the absorption coefficient with this arrangement of the counters is much less

Organic Responses to Cosmic Rays and Their Secondaries

1954
The invasion into the earth’s atmosphere and disintegration of cosmic protons is followed successively by the birth of π-mesons, μ-mesons, electrons, neutrinos, gamma photons, negatron-positron pairs, and ionization. Shower electrons are produced by cosmic-ray particles that penetrate into heavy matter.

The cosmic ?-ray spectrum from secondary particle production in cosmic-ray interactions

Astrophysics and Space Science, 1970
The cosmic γ-ray spectrum below 1 GeV arising from cosmic ray p-p interactions is calculated. Its characteristics are determined by the properties of secondary neutral pion production occurring at accelerator energies. A model is chosen for numerical calculations in which the two dominant modes of neutral pion production at accelerator energies are the

Secondary Cosmic Rays Underground and in the Atmosphere

2004
Primary CR of galactic and solar origin (mostly protons and nuclei of different Z) undergo nuclear interactions with air atoms and generate a lot of secondary particles (secondary CR). As will be shown in Chapter 11, secondary relativistic positrons and electrons are responsible for lightning between clouds and ground, and between two clouds, as well ...
