Spectroscopic studies of shock tube plasmas James, Harry Gordon

Abstract

Spectroscopic measurements were made on plasmas in electromagnetic shock tubes to test the state of equilibrium in these plasmas. In an Argon-Oxygen mixture the relative intensities of AII and AIII lines and of OII lines indicated that complete equilibrium was not established. In a Helium plasma the observed line intensities showed that the populations of the Hel levels agreed with a Boltzmann equilibrium distribution.
