Recent results of the Filippov‐type PF experiments at Kurchatov Institute

The experiments with various plasma‐producing substances performed recently were the main content at the PF‐3 facility studies: (i) The dependence of the wire array compression on the number of wires was investigated with the deuterium as a filling gas. (ii) The neutron output, 5⋅106 neutrons per shot, was registered in experiments with deuterium‐polythene fibers when argon was used as a filling gas. Experimental confirmation of fibers pre‐heating by radiation of the current sheath compressed to an axis was obtained. (iii) Studies of interaction of dense high‐temperature plasma with the condensed disperse substance (dust) were continued. The dependence of the pinch dynamics on the dust target parameters was investigated. In the shots with dust fraction of the fine‐disperse Al2O3 powder, modes with increased pinch MHD‐stability are found.
