Optimization of the Low-Intensity Beam Extraction Mode at the Medical Synchrotron for Application in Proton Radiography and Tomography

Proton therapy is one of the rapidly developing types of radiation therapy for oncological diseases. The use of proton imaging, a method in which the relative stopping power for protons is reconstructed directly, can significantly increase the accuracy and effectiveness of the proton therapy.

Summary:Proton therapy is one of the rapidly developing types of radiation therapy for oncological diseases. The use of proton imaging, a method in which the relative stopping power for protons is reconstructed directly, can significantly increase the accuracy and effectiveness of the proton therapy. This paper demonstrates the results of experimental work that was carried out at the synchrotron of the Prometheus proton therapy complex. The optimization of the synchrotron operating mode with low-intensity beam extraction was done for proton radiography and tomography purposes. Data about key changes of the beam extraction parameters for low-particles flux, as well as low-intensity beam control methods, are described.
