There is great interest in our and other contries in cascade blankets. Theoretical and design work has been done on cascade blankets but up to now no experimental work has been done. The first experiments in the world were performed at the All-Russia Reserach Institute of Experimental Physics in 2003-2004 on deeply subcritical uranium- neptunium assemblies. Three series of experiments on cascade and the corresponding single-section blanket models have been peformed. The experiments have confirmed the theoretical conclusions that cascade blankets have positive properties and that 237Np is effective in them; they have provided valuable experience in operating cascade setups with an electron accelerator. The good agreement between the measurements and the calculations has increased confidence in the computational results obtained for cascade blankets with real values of keff. The results of the second and third experiments and a general conclusion concerninig all three series of experiments are presented in this paper. © 2006 Springer Science+Business Media, Inc.
Kolesov, V.F., Il'kaev, R.I., Zhitnik, A.K. , Khoruzhii, V.Kh. Computational characteristics of a neutron source based on the CERN colliding-beams accelerator // Atomic Energy, 2006, Volume 100, Issue 2, Pages 114-122
The computational characteristics of a pulsed source of thermal neutrons, which can be implented on the basis of the collidng-beams accelerator under construction at CERN, are presented. The calculations were performed at the All-Russia Reserach Institute of Experimental Physics (Sarov) using two Monte Carlo programs: the GEANT-3 program developed at CERN and our own program S-95. The neutron source is assumed to be a cylindrical tungsten target with an internal neutron moderator made of zirconium hydride bombarded by protons from a colliding-beam accelerator. The maximum power of the source is estimated on the basis of the results of calculations of the dynamical stresses in tungsten. To decrease the negative impact of mechanical stresses, recommendations are formulated dividing the target efficiently into individual elements. © 2006 Springer Science+Business Media, Inc.

Lack of direct DNA damage in human blood leukocytes and lymphocytes after in vitro exposure to high power microwave pulses // Bioelectromagnetics, 2006, Volume 27, Issue 3, Pages 197-203

Currently, the potential genotoxicity of high power microwave pulses (HPMP) is not clear. Using the alkaline single cell gel electrophoresis assay, also known as the alkaline comet assay, we studied the effects of HPMP (8.8 GHz, 180 ns pulse width, peak power 65 kW, pulse repetition frequency 50 Hz) on DNA of human whole-blood leukocytes and isolated lymphocytes. The cell suspensions were exposed to HPMP for 40 min in a rectangular waveguide. The average SAR calculated from the temperature kinetics was about 1.6 kW/kg (peak SAR was about 300 MW/kg). The steady-state temperature rise in the 50 .gif){kind=small}
l samples exposed to HPMP was 3.5 ± 0.1 °C. In independent experiments, we did not find any statistically significant DNA damage manifested immediately after in vitro HPMP exposure of human blood leukocytes or lymphocytes or after HPMP exposure of leukocytes subsequently incubated at 37 °C for 30 min. Our results indicate that HPMP under the given exposure conditions did not induce DNA strand breaks, alkali-labile sites, and incomplete excision repair sites, which could be detected by the alkaline comet assay. © 2005 Wiley-Liss, Inc.

Ge-filled carbon nanotubes (CNTs) with an average diameter of 15-100 nm, and Ge-filled carbon microtubes (CMTs) with an average diameter of 100-8000 nm, with diamondlike structures have been prepared by metal-organic (MO)CVD from organogermanium precursors [(C2H5)4Ge and (n-C4H9)4Ge)]. These new composite structures of arrays of CNTs/germanium nanowires (GeNWs) and CMTs/GeNWs have been characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic force microscopy (AFM), scanning Auger microscopy (SAM), Raman spectroscopy, and field-emission measurements. The promising field-emission properties observed for mixtures of CNTs/GeNWs and CMTs/GeNWs form a basis for important applications of these new hybrid nanomaterials. © 2006 WILEY-VCH Verlag GmbH & Co.

Proskudin, V.F. Electromotive force for solid-flame combustion of heterogeneous systems in loose and pressed states // Combustion, Explosion and Shock Waves, 2006, Volume 42, Issue 4, Pages 430-435
By an example of condensed 3Zr + 2WO3 and Al + Ni systems, it is demonstrated that the electromotive force of solid-flame combustion measured by probing in loose systems is significantly higher than that in the same systems in a pressed state. An explanation for this phenomenon is offered, based on the difference in electrical conductivity in different zones of the combustion wave in loose and pressed condensed systems. © 2006 Springer Science+Business Media, Inc.

Kopyshev, V.P., Medvedev, A.B., Khrustalev, V.V. Equation of state of explosion products on the basis of a modified Van der Waals model // Combustion, Explosion and Shock Waves, 2006, Volume 42, Issue 1, Pages 76-87
A semi-empirical model is proposed for the equation of state of high explosives in a range of pressures and temperatures typical of detonation processes. A possibility of formation of solid phases (e.g., graphite or diamond) in the gas is implied. The model can be used to calculate all thermodynamic quantities for arbitrary molecular compositions and to calculate the thermodynamically equilibrium molecular (and phase) composition. An iterative scheme of calculations is proposed. The model contains several empirical functions whose form can be changed without violating the overall calculation scheme. A particular set of these functions is considered as an illustration. Some results calculated for a number of high explosives containing four elements (C, H, N, and O) are presented. The calculated results are compared with available experimental data. © 2006 Springer Science + Business Media, Inc.

Properties of optically transparent materials under quasi-entropic compression // Combustion, Explosion and Shock Waves, 2006, Volume 42, Issue 3, Pages 351-355
Variation in the refractive index in polymethyl methacrylate and lithium fluoride under quasi-entropic loading was studied experimentally. The values of the refractive index and the correction coefficient in the formula for the mass velocity were determined. The results obtained for quasi-entropic loading are compared with available data for shock-wave compression of the materials studied. © 2006 Springer Science+Business Media, Inc.
Bessarab, A.V., Garanin, S.G., Martynenko, S.P., Prudkoy, N.A., Soldatov, A.V., Terekhin, V.A., Trutnev, Yu.A. An ultrawideband electromagnetic pulse transmitter initiated by a picosecond laser // Doklady Physics, 2006, Volume 5, Issue 12, Pages 651-665
The designing of ultrawideband electromagnetic pulses (EMP) based on a new technology employing short-pulsed laser radiation is discussed. The transmitter comprises a metal paraboloid of revolution with an axial hole for the laser radiation entry and a condensed target situated at the paraboloid focus. The interaction of laser radiation with the target leads to the formation of a laser plasma source producing a spherically divergent flux of soft x-ray and UV radiation quanta. X-ray quanta absorbed by the inner surface of the parabolic reflector lead to the production of photoelectrons, which are emitted normally to the surface. The energy source for such an emitter is the electrostatic field that is initially created in the capacitor diode of the parabolic shape.
