  Applied research at the NICA accelerator complex include the following areas that are under construction: single event effects testing on capsulated microchips (energy range of 150-500 MeV/n) at the Irradiation Setup for Components of Radioelectronic Apparature (ISCRA) and on decapsulated microchips (ion energy up to 3,2 MeV/n) at the Station of CHip Irradiation (SOCHI), space radiobiological research and modelling of influence of heavy charged particles on cognitive functions of the brain of small laboratory animals and primates (ener-gy range 500-1000 MeV/n) at the Setup for Investigation of Medical Biological Objects (SIMBO). Description of main systems and beam parameters at the ISCRA, SOCHI and SIMBO applied research stations is presented. The new beam transfer lines from the Nuclotron to ISCRA and SIMBO stations, and from HILAC to SOCHI station are being constructed. Description of the transfer lines layout, the magnets and diagnostic detectors, results of the beam dynamics simulations are described given.

The pyroelectric effect in lithium tantalate (LiTaO3) single crystals provides a curious possibility to generate fluxes of electrons and x-rays with energy up to 100 keV. Basic conditions for initiation of this phenomenon are low pressure of residual gas around the pyroelectric crystal (0.1 - 10 mTorr) and changing of its temperature. However, this way of particles generation does not become widely used yet due to the instability of generated particle flux. Here we present that application of sinusoidal changing of temperature may overcome this shortcoming and obtain a quasi-stable X-ray and electron pyroelectric source. We managed to observe and characterise the avalanche process at the pyroelectric effect. This phenomenon is responsible for the multiplication of electrons and X-rays. The great potential of this compact X-ray source by performing reliable energy-dispersive X-ray spectroscopy for element analysis of two solid samples was demonstrated.
