Opis:
Experimental investigations were performed to evaluate the focusing properties of the plasma focus for high-energy intense ion beams manipulating. Magnetic probes and optical spectroscopy were used for temporal and spatial plasma geometry investigations. Ion beam portrait was determined at the luminescence screen. In the experiments performed, the focusing coefficient was obtained as the ten times beam compression at the 30 cm length. By variations of the gas volume input, gun voltage, time delay, magnetic field value etc. the dependence of focused ion beam diameter upon various parameters of the plasma focus lens has been investigated. It was revealed that the main focusing effect was caused by the azimuthal magnetic field of the currents carried by the plasma.

The report describes some of the results obtained in an experimental study of the impact of a powerful plasma stream and a fast ion beam generated in a PF-1000 device on different materials perspective for the use in radiation loaded parts of pulsed plasma installations. Investigations were done during and after the interaction processes. It is shown that in case of irradiation of samples only by high power flux density plasma streams the effect of detachment still preserved. At the same time a low power flux density high-energy ion beam plays an important role in the process of saturation of the irradiated material by hydrogen.

Opis:
In the article the function and the scale for the entropy evaluation of the current state of extremely high frequency (EHF-) sensors quality in the various technical systems which fits the requirements of universality and maximal independency from the human factor are offered. One may see such EHF-sensors for the analysis of the quick transformations of the biological liquids properties. It’s high lighted that the available methods of the determination of technical systems’ quality have essential flaws which consist in both subjectivism because the dominant role in the evaluation belongs to experts and legitimacy of providing them properties of universality which was proved by nobody. The scheme of EHF-sensor is analyzed for which one may create an analytical model. The problem of the fields’ determination at the working region of such sensor is discussed. The presented scheme is possible to use for the mathematical model and just for that part of the problem which is devoted to the transformation of the properties of the object. The results of calculation of components of electromagnetic field at the working space of EHF-sensor are discussed. One may estimate the sizes of this space. The offered function of the quality evaluation, the parameter of which is the quantity of own information of the explored sensor, provides the declared universality approach according to the principles of the information theory. The conformity to all requirements for the functions of the evaluation of the quality: continuity, monotonic and smoothness over the whole range of definition regardless of the probability distribution function, which is measured by the random value EHF-sensor was proved. The proposed scale of the entropy evaluation of the quality fits to standard settings of the diagnostic of the technical systems and has three sub ranges which determine the state of the EHF-sensors: good state, up state, and down state. Unlike the existing psychophysical scales the offered scale has dynamic range of the evaluation so the limits of the sub ranges will automatically change depending on the regulatory and technical requirements for the state of the explored EHF-sensor. Such approach provides adaptation of the scale to specific requirements which gives a chance to evaluate the qualitative state of the object more reliably. The results of modeling of the qualitative state of the sensor are given. The possible practical application of the offered function and scale is usage in the systems of monitoring and diagnostic for determination of the current qualitative state of the explored technical system, as well.

Opis:
We report on design and fabrication of alternately-strained $ZnS_xSe_{1-x}$/CdSe short period superlattices with the effective band-gap 2.52, 2.58, and 2.61 eV and the total thickness ≈300 nm. Transmission electron microscopy, X-ray diffraction, and photoluminescence measurements reveal negligibly small density of misfit dislocations in the superlattices. The investigation of carrier transport along the superlattice growth axis, performed by the photoluminescence measurements of a superlattice with one enlarged quantum well, confirms efficient Bloch-type transport at temperatures above ≈ 100 K. Such superlattices look promising for the applications as a material for the wide band-gap photoactive region of a multi-junction solar cell comprising both III-V and II-VI materials.

In this report we present a first series of tests of the lithium Capillary Porous System (CPS). We suppose that such a system can be used as a first wall in a thermonuclear reactor. The main goal of the presented work was to study the behavior of the lithium CPS in the condition simulating the influence of plasma in various operating regimes of the thermonuclear reactor. The tests were conducted in a Plasma Focus (PF) installation. The preliminary analysis of the received results confirms the high resistance of the lithium CPS to the pulse influence of plasma flows.

Instabilities of light emission and also of stimulated emission in series of GaN epilayers and InGaN quantum well structures, including laser diode structures, are studied. A stimulated emission is observed under electron beam pumping. This enabled us to study light emission properties from laser structures and their relation to microstructure details. We demonstrate large in-plane fluctuations of light emission and that these fluctuations are also present for excitation densities larger than the threshold densities for the stimulated emission.

Opis:
Changes in the optical characteristics in synthetic sapphire specimens produced by microsecond pulse irradiation with a stream of hydrogen ions of energies ranging up to tens keV have been observed. Data on decrease in the optical reflection, measured within the wavelength range of 200 900 nm, are presented. This characterization is compared with the data received by optical and atomic force microscopy as well as by lattice structure analysis performed with X-rays. The measurements indicate that the changes of optical parameters are not a consequence of absorption increase and/or sapphire decomposition. They result from modifications of the morphology and structure of surface layer of the sapphire samples, induced by irradiation.

A review of results on the design and operation of the new efficient Dense Plasma Focus device PF-6 of medium size (transportable) having bank energy of ca. 7 kJ and possessing a long lifetime is presented. New data on the interaction of the pulsed fast ion beams and dense plasma streams generated at this apparatus with various materials are given. These results are compared with the analogous information received at the biggest facility PF-1000. It is shown that it is possible to have about the same power flux density (in the range of 105 109 W/cm2) in both devices however in different areas. Doses of soft X-rays produced by the device within the resists for the goals of microlithography and micromachining appear to be several times less that it is with the conventional X-ray tube. In biological application of this device, medium- and hard-energy X-rays are exploited in the field of radioenzymology. It was found that the necessary dose producing activation/inactivation of enzymes can be by several orders of magnitude lower if used at a high-power flux density in comparison with those received with isotope sources. In medicine, short-life isotope production for the goals of the positron emission tomography (medicine diagnostics) is possible by means of the fast ions generated within DPF. All these experiments are discussed in the framework of pulsed radiation physics and chemistry in its perfect sense thereto the criteria are formulated.

Opis:
This paper reports on theoretical calculations and fabrication by molecular beam epitaxy of wide-gap II-VI heterostructures emitting in the "true" yellow range (560-600 nm) at room temperature. The active region of the structures comprises CdSe quantum dot active layer embedded into a strained $Zn_{1-x}Cd_{x}Se$ (x=0.2-0.5) quantum well surrounded by a Zn(S,Se)/ZnSe superlattice. Calculations of the CdSe/(Zn,Cd)Se/Zn(S,Se) quantum dot-quantum well luminescence wavelength performed using the envelope-function approximation predict rather narrow range of the total $Zn_{1-x}Cd_{x}Se$ quantum well thicknesses (d ≈ 2-4 nm) reducing efficiently the emission wavelength, while the variation of x (0.2-0.5) has much stronger effect. The calculations are in a reasonable agreement with the experimental data obtained on a series of test heterostructures. The maximum experimentally achieved emission wavelength at 300 K is as high as 600 nm, while the intense room temperature photoluminescence has been observed up to λ =590 nm only. To keep the structure pseudomorphic to GaAs as a whole the tensile-strained surrounding $ZnS_{0.17}Se_{0.83}$/ZnSe superlattice were introduced to compensate the compressive stress induced by the $Zn_{1-x}Cd_{x}Se$ quantum well. The graded-index waveguide laser heterostructure with a CdSe/$Zn_{0.65}Cd_{0.35}Se$/Zn(S,Se) quantum dot-quantum well active region emitting at λ =576 nm (T=300 K) with the 77 to 300 K intensity ratio of 2.5 has been demonstrated.
