Abstract

This paper describes the theory, development, and experimental application of an instrument designed to measure small relative temperature fluctuations associated with traveling acoustic waves in a combustion plasma by observing potassium line radiation. The instrument has been used successfully to measure relative temperature fluctuations of <0.1% in a combustion plasma under conditions representative of magnetohydrodynamic power generation.
