The Alpha Magnetic Spectrometer (AMS) is a general purpose high energy particle detector that was deployed to the International Space Station (ISS) on May 19, 2011 to conduct a unique long duration mission of fundamental physics research from outer space. Among the physics objectives of AMS are a search for Dark Matter and Antimatter, the study of the propagation mechanisms of cosmic rays and the exploration of new scientific phenomena that can not be achieved on ground based experiments.

After five years of operations in space, AMS has collected over hundred billion cosmic ray events and has provided precision measurements of electrons, positrons, protons, antiprotons, and nuclei of helium, lithium, boron, carbon and oxygen up to multi-TeV energies. As an external payload on the ISS until at least 2024, AMS will continue to collect and analyze an increasing set of data at highest energies which, combined with an in-depth knowledge of the detector and systematic errors, will provide new insights in this field.

CIEMAT and IAC have participated in the AMS Experiment since 1997 and 2003 respectively. Both groups have successfully accomplished their contributions during the construction and assembly phase of the AMS detector and are actively participating in the exploitation of scientific data.

The main goal of the coordinated project is to continue the CIEMAT and IAC participation in the AMS experiment for the next three years. The main activities will be focused on the detector operation and the analysis of the AMS science data.

The project is complemented by additional objectives that will be developed independently in each of the subprojects.

In the case of the CIEMAT subproject, the objective is to continue the R&D program for future cosmic ray detectors in space that the group started in 2015 within the CaloCube project that has provided the definition, manufacture and validation of the readout and trigger systems for scintillating calorimeters in space. The current project proposes to adapt this system for its potential implementation in the HERD Experiment.

In the case of IAC, the group will also continue its activities within the MAGIC collaboration to complement AMS observations and in the construction of the first 4 Large Size Telescopes (LST) of the Čerenkov Telescope Array (CTA) at the Observatorio del Roque de los Muchachos (La Palma). The IAC is also preparing for the physics exploitation of the LST1 and to contribute to joint observations with the MAGIC telescopes, to allow to cross-calibrate the instrument and extract first science.
