The PAMELA satellite-borne experiment was launched on 15 June 2006 from the Baikonur cosmod- rome and it has been collecting data since then. The apparatus comprises a time-of-flight system, a silicon- microstrip magnetic spectrometer, a silicon-tungsten electro- magnetic calorimeter, an anticoincidence system, a shower tail counter scintillator and a neutron detector. The com- bination of these devices allows precision studies of the charged cosmic radiation to be conducted over a wide en…

H, He, Li and Be Isotopes in the PAMELA-Experiment
On the 15th of June 2006, the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome and it has been collecting data since July 2006. The apparatus comprises a time-of-flight
LISA Pathfinder test-mass charging during galactic cosmic-ray flux short-term variations
Metal free-floating test masses aboard the future interferometers devoted to gravitational wave detection in space are charged by galactic and solar cosmic rays with energies 100 MeV/n. This process
A database of charged cosmic rays
A new online database and associated online tools ( data selection, data export, plots, etc.) for charged cosmic-ray measurements are given and new data can be submitted, providing the community with a collaborative tool to archive past and future cosmic-rays measurements.


The cosmic-ray hydrogen and helium spectra have been measured by the Balloon Borne Experiment with a Superconducting Solenoid Spectrometer (BESS), which has been Ñown from Lynn Lake, Manitoba,
The cosmic-ray He-3/He-4 ratio from 100 to 1600 MeV/amu
The Superconducting Magnet Instrument for Light Isotopes (SMILI) flew for 19 hours on September 1, 1989, with a residual overburden of 5 g/sq cm. It measured the charge, rigidity, and velocity of
A Measurement of Cosmic Ray Deuterium from 0.5-2.9 GeV/nucleon
The rare isotopes ^(2)H and ^(3)He in cosmic rays are believed to originate mainly from the interaction of high energy protons and helium with the galactic interstellar medium. The unique propagation
A measurement of the cosmic-ray H-2 and He-3 spectra and H-2/He-4 and He-3/He-4 ratios in 1989
The energy spectra of H-2 and H-3 nuclei up to energies of 450 and 800 MeV nucleon, respectively, were measured during a balloon flight of the NASA/NMSU Balloon Borne Magnet Facility on September 5,
Deuterium and He-3 in cosmic rays
Observation of a large flux of antiprotons in cosmic rays prompted many to postulate new ideas relating to the origin and propagation of cosmic rays in the Galaxy, within the framework of the
Solar modulation of galactic cosmic rays.
The modulation of galactic protons and He nuclei during the last solar cycle is analyzed according to Parker's theory. The mechanism of modulation remains essentially the same during several years of
Constraints on Cosmic-ray Propagation Models from A Global Bayesian Analysis
Research in many areas of modern physics such as, e.g., indirect searches for dark matter and particle acceleration in supernova remnant shocks rely heavily on studies of cosmic rays (CRs) and
Dissipation of magnetohydrodynamic waves on energetic particles : Impact on interstellar turbulence and cosmic-ray transport
The physical processes involved in diffusion of Galactic cosmic rays in the interstellar medium are addressed. We study the possibility that the nonlinear MHD cascade sets the power-law spectrum of
Solar modulation of galactic cosmic rays, 2
The equations governing cosmic-ray modulation allowing for convection, diffusion, and energy changes are approximated with simpler, more manageable equations that describe the particle behavior in a
