Resumen: In protontherapy, the uncertainties in the range of the beam delivered to the patient result in some safety margins in the planning that limit the dose that can be delivered to the tumour. For this reason, there is an intensive research program aiming at in vivo range verification. In particular, positron emitters are induced on C, N, O, Ca and P nuclei by the protons of the beam in the patient. Based on this, in vivo PET range verification relies on the comparison of measured and simulated activity distributions of these isotopes. The accuracy of the simulated distribution depends on the accuracy of the cross section for the production of these positron emitters. A revision of the experimental data available in the EXFOR database shows that the corresponding cross sections do not always cover the full energy range of interest, and that there are sizeable differences between the different measurements. The aim of this study is to develop a method for measuring the production cross section...
