Fast compression of liners is under consideration as a possible approach to electric energy conversion into X-ray pulse at the energy scale of dozens of megajoules. Scientific cooperation including TRINITI, Kurchatov institute, Efremov institute, and VNIITF develops the "Baikal" project in which an inductive storage has to be used which in the case of successive transformation procedure could produce an electric pulse with parameters adequate for these purposes. On the S-300 pulsed power generator, experiments is being carried out studying promising schemes of output devices for the next generation of machines. In particular, a device similar to the plasma flow switch is being investigated aimed to sharpening the current ns. The results of experiments on a current implosion of multi-wire arrays on Angara-5-1 facility are presented. There are given experimental proofs that the formation of Z-pinch takes place at temporally spread plasma production. The phenomena of temporally spread plasma production determines mode and quality of final stage of a pinch. The temporally spread plasma formation is not a hindrance to obtain high power of X-radiation output at compression and heating of a Z-pinch.
