Foam liner preionisation by external current shell on "PF-1000" and "Angara-5-1"

Results of first experiments on powerful plasma focus PF-1000 (IFPiLM), loaded by low mass foam liners, produced for "Angara" (TRINITI) liner implosion program, are presented in this report. An interaction of PF current plasma shell and the liner was the problem of main interest in our joint experiment. The main goal is to elaborate new method of plasma liner production for its compact implosion using multiterawatt pulsed power driver.
