| Zusammenfassung | The frequency distribution of clustered ionizations produced by a proton beam was measured in a nanodosimetric volume of the size of a DNA segment by means of an ion counting nanodosimeter in the energy range from 0.4 MeV to 3.5 MeV. In order to meet the needs of the ion counting nanodosimeter, the accelerator’s primary beam was reduced in intensity by means of Rutherford scattering. The comparison between experimental results and Monte Carlo simulations show a good agreement in the energy dependence of the mean cluster size, whilst the experimental cluster size distributions show a higher amount of large ionization clusters as compared to those obtained with the simulations. |
