NARROW-BAND DETECTOR FOR 1460 A

Abstract

The development is discussed of a narrow-band ultraviolet photometer that can be used to measure neutral molecular oxygen densities in the upper atmosphere. The results of an analysis of a suitable detector are presented which led to the decision to investigate the gas-filled, ionchamber detector. Properties of the materials for the construction of this chamber are given. Sapphire was selected as the window material and mesitylene as the filling gas. The experimental apparatus used, the methods employed, and some calculations which indicate expected output of the mesitylene-sapphire combination are discussed. (Author)
