Parametric x-ray radiation in the backward geometry

Parametric X-ray Radiation registered in the backward geometry is analysed. The main properties of the radiation for such geometry are discussed. The advantages of the backward geometry over other configurations regarding the intensity, the spectral width and the possibility to discriminate the contributions form different radiation mechanisms to the total radiation yield are presente

A review of the existing theories, perspectives of application and performed experiments is presented. The evolution of experimental capabilities as well as the progress in the process comprehension is illustrated. The state of the art of PXR in polycrystals is presente

The study of the guiding process for 10 keV electrons by planar Plexiglass surfaces

Experimental study of electron beam reflection from a single planar surface of Plexiglas was made. The distinct guiding effect for the part of the beam was observed for 10 keV electrons within angles of incidence from 0 to +3 degrees. The experiments using Poly plates showed a number of features of the process such as the dependence of the reflection on the plate surface quality and material of the surfaces, the divisions of the beam into two parts with different behaviour depend on tilt angle and the beam current value, the effect of an elevation angle of the beam in compare with initial beam trace at negative and zero tilt angles of the plat

Experimental station with continuous electron beam for investigation of various mechanisms of EM radiation generation

In this report we describe a new facility designed, manufactured and commissioned at Belgorod National Research University. It is a compact and cost-efficient low energy continuous electron beam installation developed to underpin research and education foundation of the University group. We present the measurements of the beam size, emittance, position and trajectory. A THz detection beam line has also been constructed and tested. The status of the THz radiation generation programme, future upgrades and experimental plans have been describe

Experimental Setup for Studying the Processes Occurring During Interaction of Fast Electrons with Matter

Experimental setup designed for studying the processes occurring under fast electrons interaction with a matter is presented. The setup is based on an electron gun, which produces the electron beam with current in range from 10 nA to 5 µA and electrons energies from 8 up to 60 keV. The rest parts of the setup are the electron gun chamber, electromagnetic system for the electron beam formation, target vacuum chamber, target goniometer, equipment for the beam diagnostics and spectrometry
