Energy concentration on S-300 pulsed power generator

Energy concentration in fast Z-pinch investigation experiments on 8-module 10 TW pulsed power S-300 generator (1.3 MV, 45 ns FWHM, 0.15 Ω) is realized by a 3-d vacuum energy concentrator. The concentrator was constructed on the basis of triplate MITLs connected parallelly at the central unit where Z-pinch is formed. At some start up experiments on 8-module installation version at 700 kV incident wave amplitude on concentrator for a gas puff load current of 4 MA with rise time of about 60 ns was obtained. The efficiency or current transfer from the concentrator input to the load for both a gas liner and a short-circuited case was practically the same.
