Summation of emission from superradiant sources as a way to obtain extreme power density microwaves

A theoretical model that covers both spontaneous and stimulated Cherenkov emission from an extended electron bunch has been developed. The initiation is described of the generation of superradiant pulses [1-3] by emission from the leading edge of the electron bunch. In combination with the proven experimentally picosecond stability of explosive emission from a cold cathode [4], it provides the possibility for strong correlation of phase of the SR pulses with respect to the leading edge of the electron pulse [5]

Development of social and communicative competence of a future teacher in the process of professional training

The article is devoted to the problem of developing social and communicative competence of future teachers in the process of their professional training. The definition of the concepts of “social and communicative competence”, “professional training of a teacher” is given. The development of the social and communicative competence of a future teacher in the process of his professional training, which is understood as an integral neoformation of a teacher’s personality, being characterized by a set of theoretical, linguistic and methodological knowledge on the development of social and communicative competence of future teachers in the process of his professional training, was considered. Pedagogical conditions for the development of social and communicative competence of future teachers in the process of their professional training were revealed. The results of the experimental work showed that if the pedagogical conditions are observed, future teachers in educational organizations have an increased desire to develop social and communicative competences and strive for achieving effective skills of interpersonal interaction and communication, as well as for knowledge of the methodological foundations and categories of pedagogy, patterns of development and formation of students’ personalities

Teachers training for arranging a developing subject-space environment in a preschool organization

The analysis of the subject-space developmental environment of the preschool educational organization included several components. Among them, we outline the assessment of the quality of the subject-space developmental environment created in each age group of the kindergarten for the general development of children. The next component is taking into account kindergarteners’ self-assessment of the correspondence of the subject-space developmental environment of the kindergarten groups to the principles of its organization. The results of the assessment of the quality of the subject-spatial developmental environment, created in each age group of the kindergarten for general development, carried out by teachers, are presented. The results of studying the potential of a preschool institution are described. It is noted that teachers highly appreciate the capabilities of the preschool institution in terms of safety, accessibility of the location of objects and manuals for children. Teachers highly appreciate the subject space in terms of stimulating various types of children’s activities, as well as the availability of zones and equipment, play material for play, cognitive, artistic and aesthetic activities

Generation, amplification, and nonlinear self-compression of powerful superradiance pulses

Superradiance (SR) of electron bunches can be considered an effective method of production of ultrashort electromagnetic pulses. Different types of SR associated with different mechanisms (cyclotron, Cherenkov, and bremsstrahlung) of stimulated emission are observed experimentally in the millimeter and centimeter wavelength bands. Progress in this research has enabled a new type of generator to be created capable of generating unique short (under 200-300 ps) electromagnetic pulses at super high peak powers exceeding 1 GW in the millimeter and 3 GW in the centimeter waveband. Some new methods for further increasing of the SR pulse peak power along with the promotion of such sources to higher frequency bands are discussed. These new methods include phase synchronization of several SR pulse generators, the amplification of an SR pulse during its propagation along a quasi-stationary electron beam and nonlinear compression in the process of induced self-transparency

Methodical system of future primary school teachers’ research skills development

The article deals with the problem of future primary school teachers’ research skills development. The relevance of the studied problem is justified by the need to form the research skills of future primary school teachers, which is one of the requirements of their professional training in higher education formulated in the Federal state educational standard (FSES) and the Professional standard of the teacher-teacher of primary school education. The aim of the article was to develop a methodical system of future primary school teachers’ research skills development in higher education, as well as process description of its experimental implementation in the educational process of the University. The research methodology includes such methods as pedagogical experiment, diagnostics, approbation, analysis, generalization. In the course of the research the following theoretical results were achieved: the purpose, objectives, components of the methodological system of development, the qualitative result of its implementation, indicated technological support of the process of future educators’ research skills development. The results of the study allowed justifying the effectiveness of the developed system of future primary school teachers’ research skills development, its theoretical and practical value. The developed methodical system, due to the validity of its effectiveness, can be used in the practice of pedagogical universities in the process of future teachers’ readiness to carry out research activities
