AMS-02 (Alpha Magnetic Spectrometer) is a multi-purpose particle physics detector that was deployed in the International Space Station (ISS) on May 19, 2011. The experiment was designed to measure the flux of cosmic rays with unprecedented precision, which allows to study the origin and propagation of cosmic rays in the Milky Way. The main scientific objectives of AMS are the search for dark matter and primordial antimatter. After 12 years of operations, AMS has collected more than 200 billion cosmic ray events and has provided precision measurements of electrons, positrons, protons, antiprotons and nuclei of helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, and

iron, up to very high energies of the order of a TeV. AMS will operate till the end of the ISS planned for 2030, collecting enough statistics to detect antimatter and to explore new physical phenomena which cannot be studied with experiments on Earth.

The astroparticle physics group of IAC has participated in the AMS experiment since 2003 in coordination with the CIEMAT astroparticle physics group, which is member of AMS since 1997. Both groups have substantially contributed to the construction phase and the detector integrations and currently actively participate in the scientific exploitation of the AMS data.

The objective of the current research project is to continue the participation of the IAC in the AMS experiment, during the next three years. The main activities will focus on detector operation and data analysis. The main objectives of the project are to obtain precision measurements of heavy nuclei,

primordial antimatter, and the anisotropy of cosmic rays.
