   Sammanfattning : New measurements of the antiproton flux and the antiproton-to-proton flux ratio at the top of the atmosphere between 80 MeV and 2.0 GeV are presented. The measurement was conducted from July 2006 to March 2008 with the PAMELA satellite experiment. LÄS MER

7. 5. Measurements of cosmic ray antiprotons with PAMELA and studies of propagation models

   Författare :Juan Wu; Mark Pearce; Fiorenza Donato; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmic ray; PAMELA; antiproton flux; propagation;

   Sammanfattning : Studying the acceleration and propagation mechanisms of Galactic cosmic rays can provide information regarding astrophysical sources, the properties of our Galaxy, and possible exotic sources such as dark matter. To understand cosmic ray acceleration and propagation mechanisms, accurate measurements of different cosmic ray elements over a wide energy range are needed. LÄS MER
