FIRST RESULT FROM THE ALPHA MAGNETIC SPECTROMETER EXPERIMENT

April 7th, 2013

The Alpha Magnetic Spectrometer (AMS) Collaboration announces the publication of its first physics result in Physical Review Letters. The AMS Experiment is the most powerful and sensitive particle physics spectrometer ever deployed in space. As seen in Figure 1, AMS is located on the exterior of the International Space Station (ISS) and, since its installation on May 19, 2011 until the present, it has measured over 30 billion cosmic rays at energies up to trillions of electron volts. Its permanent

AMS HADRONIC TOMOGRAPHY

September 29th, 2012

Operating in the International Space Station since May 2011, AMS is performing very accurate measurements of cosmic ray (e.g. Proton and Helium nuclei) with unprecedent sensitivity. This picture represents a “tomographic” reconstruction of the AMS top-of-instrument material obtained using the Proton-to-Helium flux ratio. Tiny changes of the interaction probabilities of these nuclei with different materials are used to trace the material inhomogenities. Detector elements such as screws, electronics boards, and mechanical interfaces are clearly recognizable.

THE ASIA POCC

July 7th, 2012

July the 3rd has been an important date for AMS: the AMS Asia Payload Operations Control Center has been inaugurated at CSIST premises in Taiwan. The Taiwanese President Ma Ying-jeou, together with government authorities attended the event. The opening ceremony took place at 10:30 a.m.: Professor Sadakazu Haino (formerly INFN-Perugia), newly appointed professor at the National Central University Center for Space Research of Taiwan, opened the cerimony with a review on the status of the research on Cosmic Rays. The
