摘要

介绍上海质子治疗装置束流输运系统的设计。输运系统将主环引出的能量为70-250MeV的质子束送入不同治疗室

并实现所需的束斑形状。匹配主要考虑共振慢引出造成的相空间畸形和治疗计划对束流形态的要求

通过TRANSPORT程序进行匹配

得到了输运系统的磁聚焦结构和线性光学参数曲线图。通过模拟发现

该设计有较大的灵活性

能满足不同的束斑形态需求。

Abstract

Shanghai proton therapy facility consists of a linac

a synchrotron and 4 treatment rooms.The proton beams of 70-250 MeV extracted from the synchrotron are delivered to the treatment rooms through beam transport lines.According to the treatment requirements

beam energy and beam spot size can be regulated.In this article

a layout of the transport system is given.The beam matching is done with Transport code.The Twiss function graphs

and the quadrupole parameters calculated for different beam energies and beam spot sizes

are given.The design goal

idea

method and results of the transport line are presented

too.
