A GRAZING INCIDENCE SPECTROGRAPH AS APPLIED TO VACUUM ULTRAVIOLET, SOFT X-RAY, PULSED PLASMA SOURCES

摘要

A 2.2-meter variable angle of incidence grazing incidence spectrograph is described for photographic recording of spectra down to 10A. Also a method for determining the absolute total fluence from a pulsed plasma source, knowing the absolute sensitivity of the instrument, is described. Spectra are presented from a low-inductance sliding spark gap and a 20-kj dense plasma focus. A program for spectram analysis is included. (Modified author abstract)
