AbstractFlows of ions with energies on the order of megaelectronvolts, which propagate both in the axial direction and in the direction perpendicular to the symmetry axis of the discharge, are recorded in a high-current low inductance vacuum spark. Estimates based on the measurements of the total charge of suprathermal electrons emitted from the re...

AbstractThe structures of carbon nanotubes synthesized by catalytic CVD in the same reactor using different carbon-containing precursors and a FeCl3 catalyst have been compared. Methane and acetylene were applied as carbon-containing precursors. Iron chloride has been applied on silicon substrates by drying a drop of its water solution on the silic...

AbstractThe generation of undulator X-ray radiation harmonics in free-electron lasers (FELs), which has been observed in different experiments, has been given an analytical explanation. Expressions for spectrum lines and radiation intensity are written in explicit form in terms of generalized Bessel and Airy functions with regard to the spreads of ...

AbstractAnalysis of the development of deformations under pulsed loading has shown the decisive role of powerful ultrasonic vibrations of a sample in the standing wave mode. The effect of mass transfer of atoms and ultrafine particles of the hardening phase from the matrix material to the spall damage zone on the microstructure of deformation bands...

AbstractAn array of ten built-in divertor probes was installed on the lower dome of the Globus-M spherical tokamak. It was used to measure the profiles of the floating potential, electron temperature, ion saturation current, and heat flux density to the divertor. It is demonstrated that there is a sharp change in the floating potentials of the prob...

AbstractGeneration of ultrawideband electromagnetic radiation by a vacuum photodiode with a plane cesium antimonide photocathode is studied. Thin aluminum plates deposited on a sapphire input window serve as the anode of the photodiode. Electron emission from the photocathode is initiated by the second-harmonic radiation (λ = 385 nm) of a titanium–...

AbstractUsing the methods of self-similarity for a laminar free-convective film boiling on a vertical finite-length surface submerged into a large volume of an arbitrarily subcooled liquid, we have derived expressions for the Nusselt criterion with a continuous transition from the film boiling in the saturated liquid to conditions of the strongly s...

AbstractTaking damping into account in the problems of structural dynamics is an important and nontrivial problem. Its complexity is primarily determined by the required specification of correct characteristics of the materials used and the choice of a model suitable for analysis. We consider some models of viscoelastic materials as regards the pos...

AbstractThe article presents the results of studying the transfer of heat and particles in the Globus-M2 spherical tokamak in discharges with neutral injection at the current ramp up. An atomic beam was injected into the tokamak plasma at a fixed toroidal magnetic field of 0.7 T. The plasma current on the plateau was varied in the range 0.2–0.3 MA....

AbstractA radio-technical scheme of a hierarchical thalamocortical brain network with an external input is developed. Various regimes of induced and self-oscillations (including hard-excitation regime) are revealed in the study of the proposed model. Parameters at which the scheme exhibits activity similar to spike-wave discharges of absence epilep...
