近一年来,由两台回旋加速器组成的兰州重离子加速器系统的建设,取得了较好的进展。注入器已基本建成,正在进行调束;主加速器主体已完成总装,进行了真空试验和高频试验,并且开始了等时性磁场垫补测量;束流运输系统和注入引出等系统,也取得了新进展。本文在过去报道的基础上,着重介绍近一年来的新进展。 In the past year, the construction of Lanzhou Heavy Ion Accelerator System consisting of two cyclotrons has made good progress. Injector has been basically completed, the beam is being tuned; the main accelerator assembly has been completed, the vacuum test and high-frequency test, and began the isochronous magnetic field pad measurement; beam transport system and injection leads to other systems, also made New progress. Based on the past reports, this article focuses on the recent progress in the past year.
