Abstract
The paper presents the results of a theoretical study and a mathematical model of radiation processes occurred during the grazing interaction of fast electrons with semi-infinite targets applied on a thin amorphous layer. The developed model considers Vavilov-Cherenkov and transition radiation mechanisms and predicts the possibility to enhance the angular radiation density under grazing incidence of fast electrons on the layer. The characteristics of possible extreme vacuum ultraviolet and soft X-ray sources are estimated.
Highlights
An important spectral range of electromagnetic radiation are the extreme vacuum ultraviolet (EUV) and soft X-ray regions which are used in various fields of science and technology [1]
This paper presents the calculation results of transition radiation (TR) and VC characteristics obtained during the interaction between fast electrons and a target which consists of a thin amorphous layer applied on the surface of a semi-infinite amorphous substrate
The model of TR and VC radiation is developed for the grazing incidence geometry of the interaction between fast electrons and a target consisting of thin amorphous layer applied on a thick amorphous substrate
Summary
An important spectral range of electromagnetic radiation are the extreme vacuum ultraviolet (EUV) and soft X-ray regions which are used in various fields of science and technology [1]. This paper presents the calculation results of TR and VC characteristics obtained during the interaction between fast electrons and a target which consists of a thin amorphous layer applied on the surface of a semi-infinite amorphous substrate (the thickness of the substrate layer is much more than the absorption length of the considered photons). Such structure of the target can be produced to develop EUV and soft X-ray radiators.
