Variant of the Protons Beam Delivery System for the Oncological Ophthalmological Center of Proton Radiation Therapy at the NRC “Kurchatov Institute”–PNPI
<b>Abstract</b>—A variant of the protons beam delivery system with an energy of 60 MeV for the future oncoophthalmological center for proton radiation therapy at the isochronous cyclotron C-80 at PNPI was designed. The requirements to the beam characteristics were defined. Based on a series of calculations, the optimal parameters and composition of the beam line elemenós are determined. It is shown that such a beam line allows one to alternately and efficiently switch from the isotope production mode on the cyclotron to the mode of operation of the center of proton radiation therapy without a fundamental overhaul of the accelerator systems.
