Abstract

A high-intensity, low-energy flash lamp for use below 2000 A is described. The radiation from a single flash, at 4000 v and 15 mfd, produces an emission continuum to 1500 A which is of sufficient intensity to be used with either photographic or photomultiplier techniques. A densitometer trace of the Schumann-Runge O₂ absorption band system is shown. Also, oscilloscope traces are presented which were taken at 1700 A. These show attenuation of the signal as a function of oxygen concentration.
