兰州重离子直线加速器是作为兰州重离子冷却储存环(CSR)未来的注入器而开始的一个新项目,其目的是为CSR提供更好束流品质及更高流强的束流,更加充分的发挥CSR的潜能,同时也可以为超重等研究直接提供束流．其设计最小荷质比为1／6,引出能量为16MeV／u,设计流强为1A·μA,工作频率为100MHz及其倍频200MHz．采用超导ECR离子源、RFQ及IH型DTL加速结构的方式,设计总长度小于40m．整个工程分阶段进行,现阶段的工作重点是第一个IH腔体之前的工作于基频的部分,本文主要介绍这部分的动力学设计及整台机器的基本参数．
The Lanzhou Heavy Ion Linear Accelerator is a new project that started as a future injector for Lanzhou Heavy Ion Cooling Storage Ring (CSR). Its purpose is to provide CSR with better beam quality and higher flow, and to give full play to CSR Of the potential, but also for the study of overweight and other direct delivery of the beam. The design of the minimum charge-to-mass ratio of 1/6, leads to energy of 16MeV / u, design flow of 1A · μA, the operating frequency of 100MHz and its multiplier 200MHz. Using superconducting ECR ion source, RFQ and IH DTL acceleration structure, the total design length of less than 40m. The whole project is carried out in stages. At this stage, the focus of work is on the part of the fundamental frequency before the first IH cavity. This paper mainly introduces the dynamic design of this part and the basic parameters of the whole machine.
