美国瓦里安公司生产的CLINAC 6X系列医用直线加速器,目前在国内中小型医院的使用率比较高,且二手机较多,大多数机器都处于维修保养期,需要由医院的维修人员来完成。在更换了与AFC有关的相应部件,如磁控管、耦合头、正交桥、延迟线或AFC放大板等以后,都需要对AFC放大板参数进行调整,但是可供参考的相应维修资料却很少。笔者在多年的加速器维护保养工作过程中,对AFC放大板参数的调整摸索到了一点经验,现与大家交流,供参考。机器状态ON,AFC红色按钮处于中间位置并呈拉出状
The CLINAC 6X series of medical linear accelerators manufactured by the Varian Company in the United States currently has relatively high utilization rates in small and medium-sized hospitals in China and more used mobile phones. Most of the machines are under maintenance and need to be completed by hospital maintenance personnel. AFC amplifier board parameters need to be adjusted after the replacement of AFC-related components, such as magnetrons, coupling heads, quadrature bridges, delay lines or AFC amplification boards, but the corresponding repair information for reference Few. The author in many years accelerator maintenance work process, AFC amplifier board parameters to explore a little bit of experience, now we communicate with you for reference. Machine status ON, AFC red button is centered and pulled out
