AERODYNAMICS PROGRAM RE-ENTRY PHYSICS. ROTATIONAL TEMPERATURE MEASUREMENTS

Abstract

A theoretical investigation is presented of the electron beam temperature probe technique. The investigation includes analytic expressions for the important spontaneous emission coefficients, analytic expressions for the important optical excitation cross sections, an expression for calculating the power radiated by each rotational line in the R branch of a given band in the N2(+) first negative system, a description of the dependence of the emitted radiation on electron flux density and other factors, and an explanation for the appearance of optical selection rules in the electron excitation process.
