Abstract : Lapp and Harris have recently shown that optical pyrometer readings made through an alkali-vapor atmosphere can be significantly affected by the light absorption of diatomic molecules. This report gives their result in a form more suitable for quick reference in Cs thermionic converter work, i.e., the pyrometer correction is plotted as a function of Cs reservoir and optical-path temperature, rather than dimer partial pressure.
