Abstract: This thesis aims at deepening and improving the methods to characterise the response of diamond detectors in view of an upgrade of the radiation monitor of the Belle II particle- physics experiment. Three types of radiation are used: α and β particles, and, for the first time in this kind of characterisation, X-rays. I employed a novel method to characterise the diamond-sensor response to β and X radiation, which exploits a silicon diode as a reference to minimise systematic uncertainties due to the poor knowledge of the radiation sources. I improved the simulation of the experimental setup over that previously used in the characterisation with α radiation. The results that I obtained represent important steps forward in the characterisation techniques for diamond sensors to be used for the radiation-monitor upgrade.
