Abstract

This paper presents a conceptual design of the compact SC230 superconducting cyclotron that accelerates a beam of protons to 230 MeV and is intended for proton therapy and biomedical research. SC230 is an isochronous four-sector cyclotron based on a shell-type magnet with a magnetic field in the center of 1.7 T. Superconducting coils will be enclosed in a cryostat; all other parts of the cyclotron are warm. Acceleration is carried out at the fourth harmonic mode of the accelerating high-frequency (HF) system consisting of four resonators located in the cyclotron valleys. The accelerator employs an internal Penning-type hot cathode source. Extraction is carried out using an electrostatic deflector located in the gap between the sectors and two passive magnetic channels.

用于质子治疗的SC230超导回旋加速器的研发

摘要

本文介绍了紧凑型SC230超导回旋加速器的概念设计,该设计可将质子束加速至230 MeV,并用于质子治疗和生物医学研究。SC230是基于壳形磁体的等时四扇区回旋加速器,磁场在1.7 T的中心。超导线圈将被封装在低温恒温器中。回旋加速器的所有其他部分都是温暖的。加速是在加速高频(HF)系统的四次谐波模式下进行的,该系统由位于回旋加速器谷中的四个谐振器组成。促进剂采用内部Penning型热阴极源。使用位于扇形区和两个无源磁通道之间的间隙中的静电偏转器进行提取。
