Neutron spectra measurements in the south Atlantic anomaly region

Radiation Measurements, 2010
Abstract In this work we present the results of measurements of the cosmic-ray neutron induced flux and spectra from the ground level up to the altitude of 2400 m, in the region between 22° S and 45° W, which is under the influence of the South Atlantic Anomaly (SAA). The measurements of neutron spectra induced by cosmic rays were carried out using a

Atmospheric cosmic rays in the South Atlantic anomaly region

Il Nuovo Cimento C, 1991
To study the production and propagation of fast secondaries particles in the atmosphere, data collected during eleven quiet-time balloon flights are analysed. Comparisons of these data with those obtained in different geomagnetic rigidity regions permit to estimate the contributions of the proton and electron components in the measured intensities ...

Equivalent Monopole Source of the Geomagnetic South Atlantic Anomaly

Pure and Applied Geophysics, 2009
The South Atlantic magnetic Anomaly (SAA) is an important feature of the present geomagnetic field. In this paper we model the space–time evolution of this anomaly over the past 400 years in terms of the resultant between a decrease of a global axial dipole and an increase of a virtual local monopole source.

The South Atlantic Magnetic Anomaly: three decades of research

Journal of Atmospheric and Terrestrial Physics, 1992
Abstract This brief review of advances in our understanding of some physical processes related to the South Atlantic Magnetic Anomaly (SAMA) is intended to highlight specific issues on which further research is needed. The discussion focuses on the origin of the SAMA, the geomagnetic storm-related effects and the impact of the SAMA on orbiting ...
