Operation analysis and maintenance of Flash-Ⅱ accelerator
-
摘要: 介绍了闪光二号加速器在实验运行过程中，Marx发生器、水介质同轴线和二极管的常见故障。Marx发生器200 kV气体开关、水介质同轴线的主开关和预脉冲开关、二极管阴极表面电场和阴阳极间隙等是各部分出现故障的主要原因，针对故障采取相应的维护措施和注意事项，可实现闪光二号加速器正常稳定的运行。Abstract: Some common operation failures are introduced for Marx generator, water dielectric transmission line, diode during the running of the Flash-Ⅱ accelerator. The 200 kV gas switch in Marx generator, the 3 MV main switch and the pre-pulse switch in transmission line, the cathode surface electric field and the gap between cathode and anode are key factors for the common failures. Some maintenance methods and precautions are introduced accordingly to realize stable operation of the accelerator.
