From September 8th to 12th, 2025, the meeting delved into in-depth discussions on atomic nuclei and isotope measurements related to the Alpha Magnetic Spectrometer (AMS) experiment aboard the International Space Station (ISS).

As a particle physics magnetic spectrometer installed on the ISS since its operation on May 19, 2011, AMS has collected over 253 billion cosmic ray data points. The current AMS collaboration is focusing on advancing heavy nuclei energy spectra and isotope measurements (such as beryllium and boron) to further our understanding of cosmic ray origins and propagation. The hybrid meeting combined in-person and virtual participation, with over 50 scholars from the United States, Switzerland, Italy, Spain, Portugal, France, and China attending onsite, while other AMS collaboration members joined remotely.

Through more than 20 presentations and specialized sessions, participants enhanced their understanding of the AMS detector and proposed improvement strategies to fully exploit experimental potential and enhance measurement precision.The AMS team from SDIAT presented progress reports and engaged in discussions across multiple domains, including heavy nuclei energy spectrum measurements, beryllium/boron isotope analysis, precise calibration of time-of-flight detectors, and Cherenkov detector calibration.

This inaugural workshop on heavy nuclei and isotope analysis has set the stage for the second round of meetings scheduled for mid-October at CERN, marking continued advancement in this field of physics research.
