A source of soft X-ray emission (9–14Å) based on the miniature 15kJ plasma focus was developed and tested. The channelled along chamber axis through an opening in inner electrode (anode). regime with a mean output more than 100 J per discharge found. At current 280kA repetition rate 3.5Hz achieved by device, its lifetime estimated to be 107 commutations (about year continuous operation). demonstration experiment irradiation resist is discussed.
This paper presents new results from studies of plasma focus (PF) systems at the Kurchatov Institute (Moscow, Russia). High efficiency discharge current transport into axial region system was demonstrated PF-3 PF facility, where experiments on implosion wire arrays by carrying sheath were performed. The switching over to array and penetration with magnetic field inside studied. emission parameters small-sized facility Wmax = 600 J When operating frequencies up 10 Hz, neutron fluxes about ∼...
Abstract This paper aims to find methods for effective pinning centres generation using shock waves in order increase the current‐carrying capability of high temperature superconductors magnetic fields. It presents results effect a wave on properties composite superconductor tapes (HTSC): YBCO(123) and Bi(2223). To generate wave, authors used interaction solid state target with speed cumulative plasma jet generated Plasma Focus setup. Shock have front‐edge pressure 10 11 Pa. The sample was...
Work peculiarities of powerful and low-temperature pulsed plasma flow accelerators, focus devices, were considered on the technological application point view. A common characteristic feature for all installations is nature formation. At first, results researches use a vacuum-arc unit in nano-engineering are presented. The powder materials obtained form clusters, composition which spherical particles found. In next experiment, was directed to graphite target its sputtering, then condensed...
This article presents data on shock waves effect the structure and critical current of superconducting MgB2 tapes. To generate waves, a plasma focus installation (PF) was used. The conductive characteristics tapes dependence intensity impact number pulses were studied. A distinct pattern change in currents transversal longitudinal magnetic fields range 2–9 T is studied at temperature 4.2 K. microstructure tape chemical composition its layer are original state after wave effect. Changes found...
Filaments in the plasma focus were investigated using a model of with London current. These structures involve forward current that flows along surface tangential discontinuity and reverse induction currents surrounding plasma, including those flow over discontinuity, where magnetic field reverses its direction. Supersonic filaments demonstrated capture by current, subsonic stationary filaments, expelled plasma.
The results are given of an experimental investigation planar and quasicylindrical laser plasma cumulation. It is shown that when radiation focused into a cone drilled in solid target (and also some cases heating plane target), the dynamic affected significantly by cumulative jets parametric instability.
