Description
Measurements of decaying charge to decayed charge ratios in cosmic rays, such as Aluminum to Magnesium, allow to constrain the cosmic-ray residence time in the Galaxy, providing complementary information on cosmic-ray propagation with respect to what can be extracted from the Beryllium isotopic composition. With 115 billion cosmic-ray events collected by AMS-02 on the International Space Station, the precision measurement of the Aluminum to Magnesium nuclei ratio in cosmic rays has become feasible. Data analysis procedures, focusing on charge calibration and selection, will be presented.
