Abstract
During the operation of elekta synergy linear accelerator, programmable pulse generator (PPG) PCB will transmit pulse repetition frequency (PRF) ENABLE signal, pass through three control areas, multileaf collimator and linac control system, then go back to PPG PCB. If everything works well, PPG PCB will provide thyristor trigger pulse to high tension area, then pulse forming network will charge and discharge normally, the magnetron will generate microwave to accelerating tube, and the linear accelerator will works properly. Otherwise, if any part works in wrong conditions, the linear accelerator will not delivery beam. During the clinical use of elekta synergy linear accelerator in our hospital, the PRF ENABLE interlock occurred several times. This article summarized the PRF EN CHK chain of elekta Synergy linear accelerator in the process of operation in our hospital, analyzed in detail the happened or possibile failures, focued on the process of troubleshooting, which might provide the reference for the related personnel.关键词
