50. Precise Measurement of the Monthly Proton Flux with AMS-02 on the ISS

The Alpha Magnetic Spectrometer (AMS-02) is a high-energy particle detector designed to perform fundamental physics research in space. It was installed on the International Space Station (ISS) on May 19, 2011, where it will operate for the next decade. During the first 30 months of operations, AMS-02 collected 41 billion events of cosmic rays between 1 GV and 1.8 TV. In this work, we...

Galactic cosmic rays (GCRs) entering the heliosphere are disturbed by the magnetic field of the Sun, which varies with a period of 11 years. The solar modulation affects the GCR fluxes up to few tens of GeV, modifying the shape and the intensity of the local interstellar spectrum (LIS). The time variation of the galactic cosmic protons at Earth can be studied indirectly on ground with...

28. TIME DEPENDENCE OF THE COSMIC-RAY ELECTRON AND POSITRON SPECTRA MEASURED BY PAMELA EXPERIMENT DURING THE 23TH SOLAR MINIMUM

Riccardo Munini (INFN - Universita Studi Trieste)

The satellite-borne PAMELA experiment has been continuously collecting data since 15th June 2006, when it was launched from the Baikonur cosmodrome to detect the charged component of cosmic rays over a wide energy range and with unprecedented statistics. The apparatus design is particularly suited for particle and antiparticle identification. The PAMELA experiment has measured the time...

12. Neutron Monitors and cosmic-ray data for solar modulation studies: systematic uncertainties and modulation level time series

David Alain Maurin (Centre National de la Recherche Scientifique (FR))

20/10/2015, 17:30

Particles count rates at given Earth location and altitude result from the convolution of (i) the interstellar (IS) cosmic-ray fluxes outside the solar cavity, (ii) the time-dependent modulation of IS into Top-of-Atmosphere (TOA) fluxes, (iii) the rigidity cut-off (or geomagnetic transmission function) and grammage at the counter location, (iv) the atmosphere response to incoming TOA cosmic...
