621. MAGNETOSPHERIC EFFECTS ON HIGH-ENERGY SOLAR PARTICLES DURING THE 2012 May 17th EVENT MEASURED WITH THE PAMELA EXPERIMENT

Mr Matteo Martucci (Laboratori Nazionali di Frascati)

Oral contribution

The great challenge in constraining scenarios for solar energetic particle (SEP) acceleration is due to the fact that the signatures of acceleration itself are heavily modified by transport within interplanetary space. During transport, SEPs are subject to pitch angle scattering by the turbulent magnetic field, adiabatic focusing, or reflections magnetic structures. Ground Level Enhancements...

1129. Study on CRE arrival distributions with PAMELA experiment

CR-EX

Oral contribution

From 2009, several experiments, like PAMELA, FERMI and AMS, have shown a rise in the fraction of positrons versus electrons+positrons. One of the most probable explanation is due to the presence of nearby sources, like SNRs or pulsars. PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) is a ballooon-borne experiment and is collecting data since 15 June 2006. Its...

1102. Direction and time dependent fluxes with AMS-02

Iris Gebauer (KIT - Karlsruhe Institute of Technology (DE))

CR-EX

Oral contribution

The Alpha Magnetic Spectrometer (AMS-02) is a state-of-the-art particle detector designed to operate as an external module on the International Space Station (ISS). In this unique space environment cosmic particles can be measured with high precision over an energy range from GeV up to a few TeV. In 2014, the AMS collaboration provided precise measurements of the electron and positron...

1110. Methods for cosmic ray anisotropy searches with AMS-02

CR-EX

Oral contribution

The Alpha Magnetic Spectrometer (AMS-02) is a state-of-the-art particle detector designed to operate as an external module on the International Space Station (ISS). In the absence of atmospheric disturbance, cosmic ray fluxes between 0.5 GeV and a few TeV can be measured with high precision. In 2014, the AMS collaboration provided precise measurements of the electron and positron...

569. The large-scale anisotropy in the PAMELA experiment.

Dr Alexander Karelin (NRNU MEPhI)

CR-EX

Oral contribution

The large-scale anisotropy (or the so-called star-diurnal wave) has been studied in the frame of research carrying out in space with the PAMELA instrument. It was studied during the time period covering 2006-2014 for the Southern and Northern hemispheres simultaneously. The cosmic ray intensity distribution was constructed in the equatorial coordinate system and anisotropy was obtained. For...

219. Small-scale anisotropies of cosmic rays from relative diffusion

Dr Philipp Mertsch (KIPAC, Stanford University)

CR-TH

Oral contribution

The arrival directions of multi-TeV cosmic rays show significant anisotropies at small angular scales. It has been argued that this small scale structure is the reflection of the local, turbulent magnetic field in the presence of a global dipole anisotropy in cosmic rays as determined by diffusion. This effect is analogous to weak gravitational lensing of temperature fluctuations of the cosmic...
