Properties of Cosmic Deuterons Measured by the Alpha Magnetic Spectrometer / AMS Collaboration
Precision measurements by the Alpha Magnetic Spectrometer (AMS) on the International Space Station of the deuteron (D) flux are presented. The measurements are based on 21×106 D nuclei in the rigidity range from 1.9 to 21 GV collected from May 2011 to April 2021. [...]

Temporal Structures in Positron Spectra and Charge-Sign Effects in Galactic Cosmic Rays / AMS Collaboration
We present the precision measurements of 11 years of daily cosmic positron fluxes in the rigidity range from 1.00 to 41.9 GV based on 3.4×106 positrons collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The positron fluxes show distinctly different time variations from the electron fluxes at short and long timescales. [...]

Measurement of $^{12}$C Fragmentation Cross Sections on C, O, and H in the Energy Range of Interest for Particle Therapy Applications / Mattei, I ; Alexandrov, A ; Alunni Solestizi, L ; Ambrosi, G ; Argiro, S ; Bartosik, N ; Battistoni, G ; Belcari, N ; Biondi, S ; Bisogni, M G et al.
In a carbon ion treatment the nuclear fragmentation of both target and beam projectiles impacts on the dose released on the tumor and on the surrounding healthy tissues. Carbon ion fragmentation occurring inside the patient body has to be studied in order to take into account this contribution. [...]

In hadron therapy, the accelerated ions, interacting with the body of the patient, cause the fragmentation of both projectile and target nuclei. The fragments interact with the human tissues depositing energy both in the entrance channel and in the volume surrounding the tumor. [...]

The FOOT FragmentatiOn Of Target Experiment / Alexandrov, Andrey (INFN, Naples) ; Alpat, Behcet (INFN, Perugia) ; Ambrosi, Giovanni (INFN, Perugia) ; Argirò, Stefano (Turin U. ; INFN, Turin) ; Battistoni, Giuseppe (INFN, Milan) ; Bisogni, Maria Giuseppina (Pisa U. ; INFN, Pisa) ; Belcari, Nicola (Pisa U. ; INFN, Pisa) ; Biondi, Silvia (INFN, Bologna ; Bologna U.) ; Bruni, Graziano (INFN, Bologna) ; Camarlinghi, Niccolò (Pisa U. ; INFN, Pisa) et al.
In proton-therapy clinical practice a constant RBE equal to 1.1 is adopted, regardless of the demonstrated RBE variations, which depends on physical and biological parameters. Among other mechanisms, nuclear interactions might influence the proton-RBE due to secondary heavier particles produced by target fragmentation that can significantly contribute to the total dose: an un-wanted and undetermined increase of normal tissues complications probability may occur.
