PAMELA's measurements of geomagnetically trapped and albedo protons
A. Bruno, O. Adriani, G. C. Barbarino +64
Data from the PAMELA satellite experiment were used to perform a detailed measurement of under-cutoff protons at low Earth orbits. On the basis of a trajectory tracing approach usi…
Modulation of galactic protons in the heliosphere during the unusual solar minimum of 2006 to 2009
M. S. Potgieter, E. E. Vos, M. Boezio +3
The last solar minimum activity period, and the consequent minimum modulation conditions for cosmic rays, was unusual. The highest levels of galactic protons were recorded at Earth…
Solar energetic particle events: trajectory analysis and flux reconstruction with PAMELA
A. Bruno, O. Adriani, G. C. Barbarino +64
The PAMELA satellite experiment is providing first direct measurements of Solar Energetic Particles (SEPs) with energies from about 80 MeV to several GeV in near-Earth space, bridg…
Performance assessment of the HERD calorimeter with a photo-diode read-out system for high-energy electron beams
O. Adriani, G. Ambrosi, M. Antonelli +63
The measurement of cosmic rays at energies exceeding 100 TeV per nucleon is crucial for enhancing the understanding of high-energy particle propagation and acceleration models in t…
Re-Entrant Albedo Proton Fluxes Measured by the PAMELA Experiment
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +56
We present a precise measurement of downward-going albedo proton fluxes for kinetic energy above 70 MeV performed by the PAMELA experiment at an altitude between 350 and 610…
The cosmic-ray positron energy spectrum measured by PAMELA
PAMELA Collaboration, O. Adriani, G. C. Barbarino +63
Precision measurements of the positron component in the cosmic radiation provide important information about the propagation of cosmic rays and the nature of particle sources in ou…
