Research into the spectral characteristics of pulsed electric discharge based on
the electrodynamic dispersive media
Skvortsov D.V.
This work is part of researches about pulsed getting of substance vapor (PGV) based on
electrodynamic disperse media.
There is assessments of pssibility of measuring temperature of substance vapor in the
work, obtained by pulsed electric discharge in tube, founded on electrodynamic dispersion
technology (EDD). Spectral is the main method of measurement. The author considers various
model approximations of the thermodynamic equilibrium. Focused mainly on LTE (local
thermodynamic equilibrium). For LTE model was assessed main criterion of applicability for
the time interval equal to 1 microsecond. Also the author made assessments of collisional and
Doppler broadening of the lines.
As the main methods of plasma temperature measurements:
1)on the relative intensities of spectral lines;
2)by Doppler broadening the profile of the line.
All ratings are encouraging in the sense of the possibility of measuring temperature.
