Information sources in the educational activities of students of a medical university

The article presents the results of a study devoted to the study of information sources that students use during the period of distance learning due to the covid-19 pandemic. During the study, it was shown that 5th year students are aware of the existence of most authoritative sources of information, however, their application in the educational process is limited. It was also shown that 56% of students participate in additional educational activities 1-2 times a year or less, which requires the development of corrective measuresВ статье приведены результаты исследования, посвященного изучению информационных источников, к которым прибегают студенты в период дистанционного обучения, обусловленного пандемией «ковид-19». В ходе исследования было показано, что студенты 5 курса осведомлены о существовании большинства авторитетных источников информации, однако применение их в учебном процессе ограничено. Также было показано, что 56% студентов участвуют в дополнительных образовательных мероприятиях 1-2 раза в год и реже, что требует разработки корректирующих мероприятий

Energy depth distribution of pulsed electron beam with wide electron kinetic energy spectrum for an aluminum target

Knowledges of pulsed electron beam characteristics is necessary for use it for scientific and practice applications. Current work analyses the pulsed electron beam extracted from the vacuum diode through a titanium foil (60 mkm) of the diode exit window. Electron beam energy depth distribution was measured for a target made of different number of aluminum foils. A pulsed electron beam with a wide range of kinetic energies was generated by the ASTRA-M accelerator (260 kV of accelerating voltage, up to 1 kA of beam current, 150 ns of beam pulse duration at FWHM). A calorimeter of total absorption and Faraday cup were used to measure beam characteristics. Calorimeter included two collectors: first one measures a beam energy after aluminum foils, and the second one measures a total beam energy. All measurements were performed at 10-5 Torr background pressure after the exit window foil. As a result, the electron kinetic energy spectrum of the beam out of diode has been reconstructed
