We present the precision measurements of 11 years daily cosmic electron fluxes in rigidity interval from 1.00 to 41.9 GV based on 2.0×10^{8} electrons collected with Alpha Magnetic Spectrometer (AMS) aboard International Space Station. The exhibit variations multiple timescales. Recurrent flux periods 27 days, 13.5 and 9 days are observed. find that show distinctly different time proton fluxes. Remarkably, a hysteresis between is observed significance greater than 6σ at rigidities below 8.5...

We report the properties of primary cosmic-ray sulfur (S) in rigidity range 2.15 GV to 3.0 TV based on 0.38×10^{6} nuclei collected by Alpha Magnetic Spectrometer experiment (AMS). observed that above 90 dependence S flux is identical Ne-Mg-Si fluxes, which different from He-C-O-Fe fluxes. found that, similar N, Na, and Al cosmic rays, over entire range, traditional rays S, Ne, Mg, C all have sizeable secondary components, Mg fluxes are well described weighted sum silicon fluorine flux,...
We present the precision measurements of 11 years daily cosmic positron fluxes in rigidity range from 1.00 to 41.9 GV based on 3.4×10^{6} positrons collected with Alpha Magnetic Spectrometer (AMS) aboard International Space Station. The show distinctly different time variations electron at short and long timescales. A hysteresis between is observed a significance greater than 5σ rigidities below 8.5 GV. On contrary, proton similar variation. Remarkably, we found that are modulated more for 7...
This paper summarizes the three-year achievements of AMS INFN Roma Sapienza research group, with a focus on their active engagement in astroparticle experiments and exploration synergistic connection between space radiobiology. Collaborating institutions like Medical Physics division IRCCS Azienda Ospedaliera-Universitaria di Bologna, they have made substantial contributions to radiobiology projects, fostering interdisciplinary collaboration. The group's has produced significant findings...
Space radiobiology is an interdisciplinary science that examines the biological effects of ionizing radiation on humans involved in aerospace missions. The knowledge risk assessment health hazard related to human space exploration crucial reducing damages induced astronauts from Galactic Cosmic Rays (GCRs) and sun-generated radiation. GCRs have been identified as one primary sources exposure space. In this context, accurate characterization possible carcinogenesis by particles mandatory for...
In the near future, all space agencies are working to restart human exploration of outside Low Earth Orbit (LEO). Crewed missions in this and next decade will see presence humans on Moon Mars surface. One main showstoppers be investigated for safe colonisation is biological effects ionising radiation that can compromise health astronauts/space workers. vital task, a principal role could done by astroparticle experiments presently operating space. Such source information crucial improving...
This paper outlines an outreach exposition named “So far , So close” featuring a replica of the Alpha Magnetic Spectrometer Payload Operation Control Room to elucidate continuous supervision and regulation space mission payloads by Earth's various control rooms. The exposition's value is magnified cutting-edge AMS collaboration software, granting access telemetry data. innovation, born during pandemic, allowed remote engagement in experiment's daily operations due physical limitations CERN...
