Puffing Deuterium Compressed by a Neon Plasma Sheath at the Initial Poloidal Magnetic Field in Plasma Focus Discharge

Popis výsledku v původním jazyce

This paper presents the results of the experimental study of the influence of the applied poloidal magnetic field on the transformation of the plasma column formed by the compression of (10 ? 3)-?g/cm deuterium injected by the gas-puff nozzle in front ofthe anode axis by the neon plasma sheath of (50 ? 10) ?g/cm at a current of 2 MA. The permanent magnet with an initial induction of 20?40 mT placed inside the anode: 1) increased the diameter of the pinch and of the stagnation; 2) depressed the evolution of instabilities and formation of the dense structures in the column; 3) delayed the dip of the current derivative in time (and start of the hard X-ray and neutron emission) 200?300 ns after the first peak of the soft X-ray emission (and the pinch witha minimal diameter near the anode); and 4) decreased the total neutron yield to 10?20%. These results were interpreted in terms of the increase in the repulsive pressure of the compressed poloidal magnetic field, which ncreases the stabi
