A transition from regular propagation to irregular chaotic is an indicator that the quark-gluon plasma is emerging. E and E' are energies before and after scattering, Q2 is the second order transfer moment; .. the control parameter depends on the collision energy [7]. The solutions of (2) with PDF of the form (3) are stable attractor structures, which correspond to the fusion of quarks and gluons into stable clusters, i.e. the hadronization of QGP [5, 10].

The introduced nonlinear equation of the quark-gluon cascade, which includes dynamical chaos, has included the effects of parton recombination.

MCNP6 CALCULATION OF NEUTRON FLUX MAP IN THE HTTR DURING NORMAL OPERATION

Therefore, the objective of this study is to provide the neutron flux map of the HTTR during normal operation using the Monte-Carlo MCNP6 code [15]. After verifying the neutron flux calculation method, the detailed neutron flux map was calculated using fmesh-tally. Fig. 7 and 8 show the thermal and fast neutron flux in the axial direction in the center cross-section of the core.

This study calculated and constructed the detailed thermal/fast neutron flux map for the HTTR using MCNP6 code.

The main conditions for irradiation of lithium ceramics in the core of the WWR-K reactor are described. When lithium ceramics are irradiated in the standard capsule, the temperature of the samples does not exceed 60°C, but when irradiated in the experimental device, the temperature of the samples can rise to 800°C. The dependence of the temperature of the samples in the radiation capsule of the experimental device on the power of the reactor is given.

The rate of tritium generation in the peripheral irradiation channel of WWR-K will be ~2 105 s-1. The reactivity effect from filling a sample capsule in the core of WWR-K will be minus 0.05 βeff for the standard capsule and minus 0.3 βeff for the experimental unit.

STRESS-STRAIN STATE OF COAL WELLS KARAGANDA BASIN

This article is considered a continuation of the work [1], where methane recovery from coal seams was discussed. They are formed during well drilling due to the occurrence of the stress-deformation state of the coal seam, as well as due to its hydraulic fracturing [2]. After the column is lowered, the ring is sealed with cement mortar.

To drill into a coal seam, we must enter the coal seam at the angle of the coal seam 3 (fig. 1). Our task is to construct a theoretical model for the development of these microcracks to provide a way to extract methane from coal seams. The resulting solution turned out to be valid only in the case where the temperature regime of the well remains constant, which, of course, is not true.

The work [25] is purely theoretical and, as in our case, is devoted to the theory of the formation of microcracks in a rock mass. The conclusions presented in the paper about the radial and axial components of the stress are in good agreement with our analytically obtained data.

ИССЛЕДОВАНИЕ РАДИАЦИОННО-СТИМУЛИРОВАННЫХ СТРУКТУРНО-ФАЗОВЫХ ПРЕВРАЩЕНИЙ В ОБЛУЧЕННОМ Zr МЕТОДОМ МЕССБАУЭРОВСКОЙ СПЕКТРОСКОПИИ

Следует отметить, что температура мишени при облучении не превышала 60 °С, чего явно недостаточно для кристаллизации и образования нанокристаллических фаз в приповерхностных слоях и большей части сплава Zr-Fe. Следует предположить, что наблюдаемый дублет D3 можно интерпретировать как твердый раствор замещения железа в α-цирконии, имеющем гексагональную плотноупакованную (ГПУ) кристаллическую решетку α-Zr(Fe).

Research on the frequency response parameters of the antenna module circuit of the high-frequency heating system of KTM tokamak plasma. The article presents the results of measuring the parameters of the amplitude-frequency characteristics (AFC) of the antenna module circuit of the system for additional high-frequency (HF) heating of the KTM tokamak plasma in laboratory conditions. A description of the antenna feeder device and the HF system of the KTM tokamak is given.

At this time, start-up work is being carried out on the KTM tokamak to start the VF additional heating system. Since the HF system consists of four modules, which includes various subsystems and components, before testing the entire HF system as an assembly, it is necessary to check and determine the parameters of the individual components of the HF system. The antenna module is part of the antenna-feeding device and is a very important component in the HF system, as it transfers energy from the generator to the tokamak plasma and thereby heats the plasma.

If the transmitting system does not match the declared operating frequency, the HF system will be mismatched, which will affect the efficiency of plasma heating and the operation of the entire HF system. It is impossible to bring the KTM tokamak to the nominal declared power without putting the system into operation for additional HF heating of the plasma. Additional components are connected to the antenna module, the influence of which must also be investigated for correct operation of the entire HF system in the future.

The article presents a method for measuring the frequency response of the antenna module and the results of determining the working parameters of the antenna module, such as: wave impedance, inductance, capacitance, resonant frequency and quality factor of the antenna module circuit, depending on various additional elements for setting the inductance.

DEVELOPMENT OF A DIGITAL EDUCATIONAL PLATFORM FOR STUDYING RADIO ENGINEERING COURSES

A characteristic feature of the development is the interface of virtual instruments, which exactly copy the appearance of real devices. The calculation of the electrodynamic characteristics (reflection coefficient |S11| and standing wave voltage ratio (VSWR)) of reflector antennas with different voltages was performed using numerical simulation programs. The user interface for the microstrip resonator (Figure 4) allows you to change the length and width of the middle conductor.

The first was implemented using 3D models of the SSC and Earth, corresponding to reality. Thus, the laboratory was carried out, which made it possible to study the principles of the operation of the radio surveillance system. All its functionality is implemented by two methods: with and without redrawing the properties of the entity under study on the entity screen, i.e.

The process of interaction of various parts of the device models included in the laboratory "Filter on a rectangular waveguide" is shown schematically in Figure 7. It is this array that is further used by all internal methods of the created class. And the server component must return the data it needs for processing upon request from the client.

After authorization, a copy of the module he or she needs is made on the user's device, preventing code duplication. The functionality of the laboratory given in the article will also be expanded to give users a deeper understanding of radio engineering processes.
