New results from the Alpha Magnetic Spectrometer on the International Space Station

September 18th, 2014

The new results on energetic cosmic ray electrons and positrons are announced today. They are based on the first 41 billion events measured with the Alpha Magnetic Spectrometer (AMS) on the International Space Station (ISS). These results provide a deeper understanding of the nature of high energy cosmic rays and shed more light on the dark matter existence.

An extraordinary self portrait of Luca Parmitano with AMS reflected on his helmet. The italian ESA astronaut, has successfully completed the first of two EVA, devoted to maintenance work and to the preparation for the forthcoming docking of the russian Multipurpose Laboratory Module. Thanks Luca for your precious work and for this beautiful image with AMS.


New results from AMS presented at ICRC 2013

Using the data collected during more than 2 years the AMS Collaboration presented at ICRC 2013 new physics results on 1) Proton spectrum from 1 GV to 1.8 TV and searches for spectral breaks 2) Helium spectrum from 2 GV to 3 TV and searches for spectral breaks 3) Electron spectrum from 1 GeV to 500 GeV 4) Positron spectrum from 1 GeV to 350 GeV 5) Positron+Electron spectrum from 0.5 Gev to  700 GeV 6) B/C ratio from 0.5 GV


New AMS results to be presented at ICRC 2013 at Rio de Janeiro, Brasil

July 6th, 2013

  We are all looking forward  for  the planned release of several new results from the AMS Collaboration at the  International Cosmic Ray Conference 2013 in Brasil. On July 8th, during a special ICRC  session dedicated to   AMS,  the  Collaboration will present new results on the precision measurement of:  proton, helium, electron, positrons and Boron/Carbon as well as the positron to electron ratio. The data correspond to 24 month of data taking, about 31 billions of trigger recorded by the
