New experimental bremsstrahlung cross-section for light ion beams up to 60 MeV and comparison to theoretical models

Recent works focused on bremsstrahlung radiation as a non-invasive tool for monitoring proton beams used in radiobiology (>20 MeV). In order to study the validity of theoretical models of bremsstrahlung cross sections, bremsstrahlung X-rays between 4 keV and 15 keV coming from a carbon target irradiated by proton beams in the energy range from 15 MeV to 50 MeV were measured by a silicon drift detector. The obtained data vary from 10 mb keV-1 to 1000 mb keV-1 and fit well the literature and with theoretical model calculation. These results strongly support that bremsstrahlung X-rays models can be used to develop promising online tools for proton beam monitoring.

Automated summary

Recent works have demonstrated the feasibility of using bremsstrahlung radiation as a non-invasive tool for monitoring proton beams. Experimental results support the use of bremsstrahlung X-ray models in developing promising online tools for proton beam monitoring.
