Position-sensitive detector for the 6-meter optical telescope

The Position-Sensitive Detector (PSD) for photometrical and spectral observation on the 6-meter optical telescope of the Special Astrophysical Observatory (Russia) is described. The PSD consists of a position-sensitive tube, amplifiers of output signals, analog-to-digital converters (ADC) and a digital logic plate, which produces a signal for ADC start and an external strob pulse for reading information by registration system. If necessary, the thermoelectric cooler can be used. The position-sensitive tube has the following main elements: a photocathode, electrodes of inverting optics, a block of microchannel plates (MCP) and a position-sensitive collector of quadrant type. The main parameters of the PSD are the diameter of the sensitive surface is 25 mm, the spatial resolution is better than 100 (\mu)m in the centre and a little worse on the periphery; the dead time is near 0.5 (\mu)s; the detection quantum efficiency is defined by the photocathode and it is not less than 0.1, as a rule; dark current is about hundreds of cps, or less, when cooling. PSD spectral sensitivity depends on the type of photocathode and input window material. We use a multialkali photocathode and a fiber or UV-glass, which gives the short- wave cut of 360 nm or 250 nm, respectively.Comment: 4 pages, 7 figures, to be published in Nuclear Instruments & Methods in Physics Researc

Youth social policy in the Russian Federation

Modern look of youth social policy in the Russian Federation began to take shape in the 90s, when, due to socio-political and administrative reorganization of the society, the state recognized the need to support young people. Youth is one of the most vulnerable social groups. In this article, it is described on methods and systems analysis techniques, summarizing the results accomplished. The key aspects of youth social policy at the federal and regional levels are also presented. It is proved that the youth is now at risk requiring care of the state. Despite more than 20 years of history of formation, youth social policy is just beginning to take shape and to go beyond the boundaries of the federal legislation. The targeted youth programs of social policy are certainly significant, but require not only testing, but also the introduction by the state of the Russian Federation.peer-reviewe

Phase and Intensity Distributions of Individual Pulses of PSR B0950+08

The distribution of the intensities of individual pulses of PSR B0950+08 as a function of the longitudes at which they appear is analyzed. The flux density of the pulsar at 111 MHz varies strongly from day to day (by up to a factor of 13) due to the passage of the radiation through the interstellar plasma (interstellar scintillation). The intensities of individual pulses can exceed the amplitude of the mean pulse profile, obtained by accumulating 770 pulses, by more than an order of magnitude. The intensity distribution along the mean profile is very different for weak and strong pulses. The differential distribution function for the intensities is a power law with index n = -1.1 +- 0.06 up to peak flux densities for individual pulses of the order of 160 Jy

The first year students’ adaptation to the study of linguistic disciplines in the framework of federal state educational standards of higher education (FSES of HE) realization of a new generation

The relevance of the research problem due to the need for effective adaptation of the first year students to the study of linguistic disciplines in the framework of Federal state educational standards of higher education realization of a new-generation, for getting information on the difficulties faced by the first-year students due to the appearance of new disciplines, innovative curricula, forms and methods of training, as well as the interest of organizers of educational process in high school in the high results of development of educational, personal and professional competences. The goal of the article lies in justification of the possibility and necessity of conducting various activities, which aimed at the successful adaptation of the students. The leading method to the study of this problem is empirical, which allows to monitor the process of adaptation of the first-year students, to carry out the measurement using a specially developed assignments, tests, etc., and comparison of the indicators; as well as the methods of mathematical statistics and graphical display of results. The set of activities are developed and tested which is necessary and sufficient for the efficient adaptation of the first-year students: organization of the tutors´ work, the use of game situations on a professional theme, various activities outside the classroom, etc. The article can be useful in practical work of linguistic disciplines teachers not only in universities, but also at schools, colleges, as well as interesting to all who are connected with the professional pedagogical activity. © 2017, Slovenska Vzdelavacia Obstaravacia.
