[en] The collection of scientific papers contains reports included in the program of the V International conference «Laser, plasma research and technologies» LaPlaz-2019, which was held from February 12 to February 15, 2019 at the NINU MEPhI. The conference was organized by the Institute of Laser and Plasma Technologies of the NINU MEPhI. The topic of the conference covers a wide range of issues: laser physics and laser technologies; plasma physics and plasma technologies; superstrong laser fields; controlled nuclear fusion; modern problems of theoretical physics, and others

[en] In this work investigations of the inhibition of the culture of Salmonella spp. on the surface of champignon mushrooms (treated with relativistic electrons in comparison with the inhibition of culture on the surface of models (model media) also treated with relativistic electrons are carried out. The irradiated samples were analyzed to determine the residual amount of surviving microflora. Quantitative characteristics of the efficiency of inhibition of Salmonella spp. were obtained under influence of various radiation doses

[en] The characteristics of a high-current impulse magnetron discharge have been studied during the reactive sputter deposition of Al in Ar/O₂ gas mixture. The dependence of deposition rate on oxygen content in the gas mixture has been measured for different power management regimes. The specific deposition rate values have been obtained for different ratios of on/off times

[en] The work is devoted to the study of multilayer film material polyamide/polyethylene with a thickness of 80 microns after its processing by an electron beam with energy of 10 MeV in doses from 3 to 18 kGy at two radiation processing plants. The structure of the polymer material before and after irradiation of each layer was studied

[en] The paper describes the physical processes during laser ablation into a liquid and during laser shock-wave pinning. It is essential that during laser pinning the treated surface is washed with water. Therefore, the physics of the processes during ablation into a liquid and during pinning turns out to be the same

[en] A complete radiative-collision model has been used for calculation of radiation intensity of multielectron atoms in plasma of linear plasma devices. Experiments on radiation of molybdenum and tungsten atoms in argon plasma of PR-2 devices have been conducted

[en] The interaction of the radio frequency capacitive discharge (RFCD) plasma with its active (electrodes) and passive (walls) boundary surfaces is considered. When plasma interacts with active surfaces, there is a complex set of physical processes – generation of DC electric fields, electron emission, formation of pulsed electron beams, excitation of various instabilities and others

[en] The integral electrical characteristics of a pulsed magnetron discharge with a hot cathode with targets made of Cr, Cu, and Si have been measured. The phase trajectories of the discharge development in the voltage – current coordinates are constructed. Based on the results obtained, the modes of stable existence of a pulsed discharge with a hot target without transition to an arc shape are determined

[en] This report provides an overview of works in which the features of the near-wall plasma and processes in it during the interaction of plasma with structures such as a conductor on a dielectric were investigated using the method of computer simulation. This formulation of the problem was initiated by experiments on the formation by the method of plasma etching of structures such as nanoribbons of graphene, topological insulators, etc. In these experiments, the plasma was created either by a low-density electron beam or by a beam-plasma discharge

[en] The issues of defrosting mineral raw materials packaged in polypropylene packaging are considered. The evaluation of the plant defrosting performance at a microwave power of 50 kW at a frequency of 915 MHz is estimated. Various designs of the microwave installation are considered and preliminary calculations of effective antenna emitters for defrosting mineral raw materials are carried out
