Abstract:This paper analyzed two cases of uncommon faults of Elekta Synergy accelerator, which was purchased by the hospital in
2010: a. There was no output of three optical fibers in isolation board of high voltage pulse modulator at the same time. The reason
was the electro-optical conversion power module faulted, which was solved by replacing the MODULATOR ISOLATION UNIT
PCB unit circuit; b. The rotation angle of Gantry was not synchronized. The reason was that the degree rack on the Gantry guide rail
was missing rack, which was solved by replacing the rack. The analysis process and causes of the above faults are different from
those described in most relevant literature, and is worth sharing with peers. In addition, this paper summarized the maintenance
experience of accelerator, which provided reference for the maintenance of equipment.
