A TWO-METER NORMAL INCIDENCE VACUUM ULTRA-VIOLET SPECTROGRAPH
|
Abstract:
A two-meter normal incidence vacuum ultra-violet spectrograph has been built and in operation for some time. The spectrograph has an angle of incidence 7.5° and covers the spectral range 2100?-200?, with an average dispersion 8.7?/mm. A low pressure condensed spark discharge tube is used as the source, giving intense sharp spectral lines of various degree of ionization. Majority (554 in number) of the emission lines has been identified.
