11月17日,我院联合航天科工集团等5家单位,成功开展了100 MeV回旋加速器首次物理实验——中能质子单粒子效应实验,填补了我国中能质子抗辐照实验技术空白。这是该加速器首批物理实验项目之一。2016年,此回旋加速器质子束性能进一步提升,内靶平均流强达到1 mA。此外,230 MeV质子治疗超导回旋加速器核心设备主磁铁和超导系统研发成功,250 MeV质子治疗项目获得国家科技部立项
On Nov. 17, 5 units of China National Aerospace Science and Industry Corporation successfully carried out the first physical experiment of a 100 MeV cyclotron - a mesoporous single-particle effect experiment, which filled in the blank of experimental technology of intermediate-proton anti-radiation in China. This is one of the first physical experiments of the accelerator. In 2016, the cyclotron further improved its proton beam performance and achieved an average target flow strength of 1 mA. In addition, the successful development of the main magnet and superconducting system of the 230 MeV proton therapy superconducting cyclotron core device, the 250 MeV proton therapy project has been approved by the State Ministry of Science and Technology
