Application of new techniques to 'Flash-II' accelerator

For keeping up with the international development of pulsed power technology, some new techniques such as the water coaxial line parallel connection, the multi-gap multi-channel gas output switch and synchronized trigger system have been studied on 'Flash-II' accelerator. 2 Ω pulse forming line (PFL) formed by three small 6 Ω PFLs with parallel connection after simulating electric field distribution on the three-dimensional and the insulation designing. The 3 MV multi-gap multi-channel gas output switches have been developed and three switches have been synchronously operated with parallel connection. Synchronized trigger system that operation delay is only 446 ns has been applied in synchronous operation between Marx generator and main switches. The water treatment technique in which whirlpool circulation has been occured in water dielectric coaxial line on vacuum condition has been developed for treating air bubble of water dielectric. After adjustment, 'Flash-II' accelerator has been operated steadily and the application of these new techniques have been succeed.
