Novikov L., Voronina E., Galanina L. et al. Physics of Atomic Nuclei. 2017. Vol. 80. No. 4. P. 666-678.

The brief history of the development of investigations at the Skobeltsyn Institute of Nuclear Physics, Moscow State University (SINP MSU) in the field of space materials science is outlined. A generalized scheme of a numerical simulation of the radiation impact on spacecraft materials and elements of spacecraft equipment is examined. The results obtained by solving some of the most important problems that modern space materials science should address in studying nuclear processes, the interaction of charged particles with matter, particle detection, the protection from ionizing radiation, and the impact of particles on nanostructures and nanomaterials are presented.

A major concern in using vanadium alloys for first wall/blanket systems in fusion reactors is their activity with regard to nonmetallic impurities in the coolants. This paper presents the results of studying the corrosion resistance in high-purity liquid lithium (with the nitrogen and carbon content of less than 10–3 wt %) of vanadium and vanadium alloys (V–1.86Ga, V–3.4Ga–0.62Si, V–4.81Ti–4.82Cr) both in the initial state and preliminarily irradiated with Ar+ ions with energy of 20 keV to a dose of 1022 m–2 at an irradiation temperature of ~400°C. The degree of corrosion was estimated by measuring the changes in the weight and microhardness. Corrosion tests were carried out under static isothermal conditions at a temperature of 600°C for 400 h. The identity of corrosion mechanisms of materials both irradiated with Ar ions and not irradiated, which consisted in an insignificant penetration of nitrogen into the materials and a substantial escape of oxygen from the materials, causing the formation of a zone with a reduced microhardness near the surface, was established. The influence of the corrosive action of lithium on the surface morphology of the materials under study was found, resulting in the manifestation of grain boundaries and slip lines on the sample surface, the latter being most clearly observed in the case of preliminary irradiation with Ar ions.

The radiation of microwave sources above sunspots at a frequency of 17 GHz gives information about the parameters of solar plasma in the regions where the magnetic-field strength is B ∼ 2000 G in the transition region between the chromosphere and corona. Short-period oscillations (with a period of severalminutes) of microwave emission from solar active regions (ARs) reflect wave processes in magnetic flux tubes of sunspots. Short-period oscillations of microwave emission from AR NOAA 12242 before two flares on December 17, 2014 are analyzed. This analysis is based on solar radio images obtained by means of the Nobeyama Radio Heliograph with a 10"−15" two-dimensional spatial resolution. The radio maps of the whole solar disk were synthesized in a nonstandard mode with a cadence of 10 s and an averaging time of 10 s. An increase in the power of about ten-minute oscillations of microwave radiation approximately 40 to 50 min before the M1.5 flare (01 : 00 UT) is found. On the same day, an increase in the power of ten-minute oscillations is observed about 60 min before the M8.7 flare (04 : 42 UT). This effect is similar to the effect found earlier by two groups of authors independently for three-minute oscillations—namely, they observed a sharp increase in three-minute oscillations 15 to 20 min before the radio burst accompanying the flare. The effect in question may be interpreted as an relationship ofMHD waves propagating along the magnetic flux tube of a sunspot and the onset of the solar flare.

Radiation of microwave sources above sunspots at a frequency of 17 GHz gives information on parameters of solar plasma in the regions of magnetic field B ~ 200 G in the transition region between chromosphere and corona. Short period (with periods in several minutes) oscillations of microwave emission of solar active regions (ARs) reflect wave processes in the magnetic flux tubes of the sunspots. We present an analysis of short period oscillations of microwave emission of AR NOAA 12242 before two flares on December 17, 2014. The analysis is based on solar radio images, obtained using the Nobeyama Radio Heliograph. The radio maps of the whole solar disk were synthesized in non-standard mode with a cadence of 10s and 10s averaging. The spatial resolution of the radio maps is about 10ʹ–15ʺ. We found that about 40–50 min before the M1.5 flare (01:00 UT) the power of about ten-minute oscillations is increased. At the same day the power of ten-minute oscillations increased about 60 min before the M8.7 flare (04:42 UT). The observed effect is similar to the previously detected independently by two authors effect for 3-minute oscillations, namely, for 15–20 min before radio burst there was increase of the power of 3-minute oscillations. The effect can be interpreted as a relationship between MHD waves, propagating along the magnetic flux tube of sunspot, and beginning of the flare.
