The 5.5 MV CN-Van de Graaff (VDG) accelerator was first installed and operated in the early 50's at Rice University (Houston, TX) and it was donated to IFUNAM (“Instituto de Fsica, Universidad Nacional Autnoma de Mxico”) in 1984 and started a new life in 1988. At the end of 2017, the ion source was severely damaged. Several power supplies were destroyed. In this article we describe the process of restoring the VDG terminal. A number of power supplies were redesigned, built, tested and mounted in the Terminal. As a result of the work carried out during most of 2019, the VDG accelerator is now operational and we show data from the Rutherford Backscattering (RBS) analysis of a platinum coated silicon slab using the first proton and α beams. Electronic diagrams of all supplies in their new configuration are provided for the benefit of this kind of RF-Ion sources users still numerous.

IFUNAM 5.5 MV CN-Van de Graaff 加速器射频离子源的修复
5.5 MV CN-Van de Graaff (VDG) 加速器于 50 年代初在莱斯大学(德克萨斯州休斯顿)首次安装和运行,并于 1984 年捐赠给了 IFUNAM(“Instituto de Fsica,Universidad Nacional Autnoma de Mxico”)并于1988年开始了新的生活。2017年底,离子源严重损坏。几个电源被毁坏。在本文中,我们描述了恢复 VDG 终端的过程。许多电源经过重新设计、制造、测试并安装在航站楼中。作为 2019 年大部分时间开展的工作的结果,VDG 加速器现已投入运行,我们展示了使用第一束质子和 α 束对镀铂硅板进行卢瑟福背散射 (RBS) 分析的数据。
