| Özet: | Title screen Experiments on imploding metal-puff Z pinches with an outer plasma shell were performed at currents of 2-3 MA on the GIT-12 generator (4.7 MA, 1.7 s) at the Institute of High Current Electronics (Tomsk). The outer plasma shell was produced by 48 plasma guns arranged in a circle of diameter 35 cm. The pinch plasma was generated by a vacuum arc which operated in a gap between an aluminum cathode and an aluminum anode. The initial mass density profiles of metal-puff pinches generated in different load configurations were estimated from experimentally obtained current and voltage waveforms, signals of magnetic probes, and images taken with a streak camera and an HSFC Pro four-frame optical camera. For radii R larger than 0.2 cm, the initial radial mass density profile of a metal-puff pinch was approximated by three Gauss functions. The central part of the pinch with R<0.2 cm was formed by an aluminum plasma jet with a uniform density. The density profiles in the adjacent jet region (0.2<R<2 cm) were provided by the contribution of the aluminum ions from the vacuum arc anode. The next density profile (2<R<14 cm) was probably determined by the mass contribution from the surface of the insulator near which the vacuum arc operated. The density peak at the periphery (14<R<16 cm) occurred due to the operation of the plasma guns at the diameter of 35 cm. Режим доступа: по договору с организацией-держателем ресурса |
