Current addition by MITL in vacuum

Water is widely used as an insulator for high power forming lines. Its high breakdown voltage and high electrical permeance gives a possibility to produce high power density flux. But an optimal wave resistance for cylindrical water forming lines is several ohm. Consequently, the power addition schemes are necessary for low impedance loads. In greatest pulsed power installations "SATURN" and "PBFA-H" (SNL, USA) water power addition schemes are used. On the contrary, "ANGARA-5-1" (TRINITI,Russia) scheme of power addition uses eight separate MIll in vacuum. Some experimental results of the parallel current addition on a common load are described in this report. Ajitter of parallel modules switching is a significant effect of "Angara- 5-1" operation. Quantitatively it is a square mean of time delay of modules T1-T8, when voltage of every module gets 0.1 of its maximal value. These moments can be defined with +/- 2 us accuracy.
