An ab initio approach to the historical modulation of cosmic rays
(North-West University (South Africa), 2021)The relationship between observed cosmic-ray intensities and the heliospheric magnetic field during the early space age is generally considered to be anomalous, relative to their relationship observed at later times. ... -
A comparison of turbulence-reduced drift coefficients of importance for the modulation of galactic cosmic-ray protons in the supersonic solar wind
(Elsevier, 2015)The study of the modulation of cosmic rays in the heliosphere relies heavily on a thorough understanding of the transport of these charged particles in the turbulent solar wind. Drift effects due to gradients and the ... -
Effects of various dissipation range onset models on the 26-day variations of low-energy galactic cosmic-ray electrons
(Elsevier, 2010)The effect of various models presented by Leamon et al. (2000) for the dissipation range cutoff wavenumber on the 26-day variations of galactic cosmic-ray electrons in a Fisk-Parker hybrid field is investigated, by means ... -
Die versyfering van historiese kosmiese straal-data = The digitization of historic cosmic-ray data
(North-West University, 2010)Due to the research on cosmic-rays in the 1930's, the Carnegie Institute in Washington DC instigated the construction of cosmic-ray observation centers around the world. Cosmic-ray activity was recorded using the model C ...
