A terawatt pulse-power generator with a microsecond plasma-openingswitch

A review of the first experiments with the GIT-4 generator is given. GIT-4 is based on the results obtained previously on Gamma (1985) and Marina (1986) generators and has operated since December 1986. GIT-4 is designed to test the concept of a terawatt pulsed-power generator based on the direct charging of an inductive storage from a Marx primary store using a plasma-opening switch (POS) at currents up to several mega-amperes. Such generators need a POS with essentially microsecond conduction times. In the experiments reviewed, output powers up to 2.5 TW in the POS region were obtained at current levels up to 1 MA     

Isotopic effects in high-energy nuclear reactions and isospin correlations of fragmentation cross sections

The experimental study of cross sections and kinematic characteristics of H, He and Li isotopes produced in the interaction of 660 MeV protons with separated isotopes of the target nuclei B, Ni, Sn and Sm, has been performed. The two-dimensional isospin correlation of cross sections for secondary particles in the nucleon-nucleus inelastic interaction is discussed. The systematization formula for fragmentation cross sections in broad regions of fragment and target nucleus masses over a large interval of incident proton energies is given.     

Uniform convergence with orderh 4 of a scheme of the method of lines for quasilinear parabolic and hyperbolic equations

The order of uniform convergence of the method of lines is considered in connection with the solution of the first boundary-value problem for quasilinear second-order parabolic and hyperbolic equations.Translated from Zapiski Nauchnykh Seminarov Leningradskogo Otdeleniya Matematicheskogo Instituta im.

Electrochemical Synthesis of Thermally Expandable Graphite Compounds in Nitrate Electrolyte

The influence of potential and time of anodic treatment of dispersed graphite in an HNO₃ solution on the intercalation rate and possible concurrent reactions was studied.
