电子直线加速器越来越广泛地应用于医疗、无损检测、集装箱稽查等领域。应用户要求,研制了一台能量为4 MeV/6 MeV的双能电子直线加速器,该加速器可工作在4 MeV单能、6 MeV单能及4 MeV和6 MeV脉间交替3种工作模式。为了满足用户现场空间的要求,对X射线机头进行了个性化的设计,将传统的纵向式机头内的元部件重新布局,变为横向式机头,且重新设计 Electronic linear accelerators are increasingly used in medical, non-destructive testing, container inspection and other fields. At the user’s request, a dual-energy electron linear accelerator with 4 MeV / 6 MeV energy was developed. The accelerator can work in 3 working modes with 4 MeV single energy, 6 MeV single energy and 4 MeV and 6 MeV pulse alternation. In order to meet the requirements of the user’s field space, the X-ray machine head was personalized design, the traditional longitudinal head of the components within the re-layout, into a horizontal head, and re-design
