Description
Nuclear fragmentation cross sections are important parameters for the
modeling of the propagation of cosmic rays through the Galaxy. These
types of measurements at energies above 10A GeV are part of the
NA61/SHINE experiment’s cosmic-ray program. The high quality of the
experiment detector was proved during pilot studies conducted
in 2018. The second measurement campaign was carried out in the
autumn of 2024. Between the two measurement campaigns, the detector
system was upgraded, which allowed for a higher rate of data collection.
This improvement enabled the registration of a large number of events
(over 40 million recorded), allowing the study of reactions induced
by a broad range of beam ions, from lithium up to silicon.
This contribution will focus on a charge-changing cross section
measurements and will discuss the methodology developed during the
pilot run, as well as the improvements based on new data and the
modernized detection system.
