Opis:: In this paper the results of the influence of physical characteristics of flat plate solar radiation concentrators made of Al sheet and Al foil on energy efficiency of PV/thermal collector are presented. The measurements results obtained by means of scanning electron microscope, reflectance and chemical composition of solar radiation concentrators are given. Optimal position of solar radiation concentrators and appropriate thermal and electrical energy of PV/thermal collector were determined. Total generated thermal and electrical energy during the day by PV/thermal collector with concentrators in optimal position are higher than the total generated thermal and electrical energy obtained by PV/thermal collector without concentrators.

Opis:: This contribution presents experimental data concerning the influence of fast heavy ions on magnetic susceptibility of VITROVAC®6025 and VITROPERM®800 metallic glasses. Samples of magnetic ribbons were irradiated with Au, and Ta ions at 11.1 MeV/A (energy per nucleon), and U ions at 5.9 MeV/A. The irradiation fluences varied from 5×$10^{10}$ up to 1.2×$10^{13}$ ions/$cm^{2}$. Relative change of the samples' magnetic susceptibility after and before irradiation was measured and evaluated as a function of the irradiation fluence. Measurements were done with a commercial Kappa-bridge device. We observed that VITROPERM® showed less change of magnetic susceptibility in comparison with VITROVAC® and this change occurred at higher fluences. This indicates higher radiation hardness of VITROPERM® compared with VITROVAC® against high-energy heavy ions. In addition, heavier ions caused larger change of magnetic susceptibility than the lighter ones and the effect could be roughly scaled with the level of electronic stopping.

Opis:: Finemet and Vitrovac® 6025 metallic glasses were irradiated by light (N) and heavy (Au and Ta) ions at different energies from 110 keV to 250 MeV/u (MeV per mass unit) and fluences from 1 × $10^{11}$ ions/$cm^2$ to 1 × $10^{17}$ ions/$cm^2$. They were analysed by the Mössbauer spectrometry and magnetic susceptibility measurements. Qualitative differences were observed between the radiation effects caused by light and heavy ions.
