Four Erythronium species have been traditionally recognised within Eurasia based on their disjunct distributions and the slight morphological divergence between them: E. dens-canis, E. caucasicum, E. sibiricum and E. japonicum. The range of E. sibiricum includes adjacent parts of southern Siberia, Kazakhstan, China and Mongolia in the Altai-Sayan mountain region. Despite several recently proposed...
In this paper we present investigation results of a vircator characteristics with a double anode grid operating in pulsed-repetitive regime. The vircator was powered from a low-inductive generator of pulsed voltages with power capacity of about 40 J. Electrons were emitted with a plain graphite cathode and injected to a parabolic drift chamber of the vircator through the anode, made of tungsten wire...
In this paper we present experimental results on electric-exploded current opening switch (EEOS) powering from fast helical magneto-cumulative generator (MCG). Energy capacity of such MCG is about ∼1 kJ, total operating time is 25 µs, characteristic current rise time (in e-times) is ∼2.5 µs. Thin copper wires we used in EEOS. Voltage pulses up to 200 kV with front ∼50 ns on resistive load of 25 Ω...
