Studies on the liner compression in the PF-3-facility modernized discharge system

In RRC ≪Kurchatov Institute≫ the studies of the plasma focus as a driver for magnetic compression of liners are going on. As a result of the discharge system modernization, the value of the discharge current has been increased up to 4 MA in its maximum and up to 3 MA in the stage of pinch formation. A number of experiments are achieved with foam and wire loads in the modernized discharge chamber at the enhanced level of the discharge current. A two-fold increase of the velocity of easy loads compression (up to ∼(6–7)×10
⁶
cm/s) is obtained. The compression of a foam liner with a linear mass of 1 mg/cm is achieved.
