This research is devoted to investigating the properties of X-ray tube models with massive carbon cathode: field emission cathode in DC-mode and pulsed explosive cathodes. Construction device described. It able operate at non-ultrahigh vacuum conditions. Two types ring cathodes were examined: metal-ceramic slits (of a comb-shaped kind) carbon-ceramic. The installation which makes it possible investigate demountable tubes was designed. Experiments show better performance pulse cathode....

Abstract CoFe 2 O 4 (111) epitaxial films on a single crystalline (100) ZrO (Y 3 ) substrates and non-oriented metal tape were grown by the metalloorganic chemical vapour deposition (MOCVD) method. The /ZrO contain coherent high-angle boundaries between variant domains due to complex distortions compared polycrystalline state of /(metal tape) film. structural peculiarities with structure lead strong anisotropy its magnetooptical properties. Moreover significant magnetorefractive effect, up 1...
This article presents a method for separation of particular energy bands from the Bremsstrahlung spectrum pulsed X-ray source purpose dual-energy imaging. We used with an inductive storage device and semiconductor opening switch. The has following parameters: pulse voltage is 91 kV, tube current up to 140 A, focal spot diameter this about 1.2 mm, repetition rate 5 kHz, duration 25 ns. contains larger amount low-energy quanta than that continuous radiation sources. Changes due application...
Представлены результаты исследования магнитооптического эффекта Керра и магнитоотражения естественного света в пленках La 2/3 Ba 1/3 MnO 3 /SrTiO разной толщины. Показано, что эффект имеет максимальные значения видимой ближней ИК-области, а магнитоотражение достигает максимума порядка 10% среднем ИК-диапазоне при температурах, близких к комнатным. Обсуждены физические механизмы, определяющие величину знак эффектов, также влияние тонкопленочного состояния на магнитооптические...
Abstract The electrical resistance and reflectance of unpolarized infrared radiation have been studied in the La 2/3 Ba 1/3 MnO 3 films with without a variant structure. Applying an external magnetic field leads to appearance magnetoreflection colossal magnetoresistance effects maxima near Curie temperature films. high-angle boundaries markedly enhance electric magnetooptical properties nanostructured epitaxial For example, additional low-temperature contribution has revealed /ZrO 2 (Y O )...
A correlation was found between the magnetoreflection of natural light and tunneling magnetoresistance in La2 / 3Ba1 3MnO3 films with a variant structure grown on ZrO2 (Y2O3) substrates. It shown that as well colossal magnetoresistance, is maximum region magnetic ordering near room temperature (Tc ~ 295 K) films. The spectra film are formed by same mechanisms case without can be described terms theory magnetorefractive effect. field dependences demonstrate presence an additional...
The electrical, optical, and magneto-optical properties of La 0.69 Ba 0.31 MnO 3-delta thin films with a Curie temperature near room are studied. It is shown that in the region phase transition there sharp change behavior dependences electrical resistance optical transparency films, which associated insulator-metal transition. In narrow transition, external magnetic field leads to appearance negative magnetoresistance magnetotransmission unpolarized light spectral range from 1 12 μm. effect...
