Abstract

A variant of the proton beam delivery system with an energy of 60 MeV for the future oncological ophthalmological center for proton radiation therapy at the isochronous cyclotron C-80 at PNPI was designed. The requirements to the beam characteristics were defined. On the basis of a series of calculations, the optimal parameters and composition of the beam line elements were 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 for proton radiation therapy without fundamental overhaul of the accelerator systems.

NRC“库尔恰托夫研究所”（PNPI）的质子射线治疗肿瘤眼科中心的质子束传输系统变体

摘要

设计了一种能量为60 MeV的质子束传输系统的变体，用于将来在PNPI等速回旋加速器C-80上进行质子放射治疗的肿瘤眼科中心。定义了对光束特性的要求。在一系列计算的基础上，确定了束线元素的最佳参数和组成。结果表明，这种束线可以使回旋加速器上的同位素产生模式交替有效地转换为质子放射治疗中心的运行模式，而无需对加速器系统进行大修。
