Antimatter and Dark Matter search in space with AMS-02

TL;DR

AMS-02 is a space-based spectrometer designed to precisely measure cosmic ray composition, aiming to detect antimatter and dark matter signatures with high sensitivity during its mission on the ISS.

Contribution

This paper introduces AMS-02, a novel high-precision space instrument capable of detecting antimatter and dark matter signals in cosmic rays.

Findings

High sensitivity to anti-Helium nuclei (one part in a billion)

Enhanced understanding of cosmic ray composition

Potential to identify dark matter signatures

Abstract

AMS-02 is a space-borne magnetic spectrometer designed to measure with very high accuracy the composition of Cosmic Rays near Earth. With a large acceptance of 5000 squared centimeters, an intense magnetic field from a superconducting magnet (0.7 T) and a very efficient particle identification, AMS-02 will provide the highest precision in Cosmic Rays measurements up to the TeV region. During a three-years mission on board of the International Space Station, AMS-02 will achieve a sensitivity to the existence of anti-Helium nuclei in the Cosmic Rays of one part in a billion, as well as provide important information on the origin and nature of the Dark Matter.
