Exploratory Development to Study Graphite Vaporization Kinetics and Thermodynamics using the Modulated Beam Mass Spectrometer

Abstract

Progress is reported in a program of mass spectrometric studies of graphite vaporization kinetics. A renewed search for polymers in the carbon vapor over very hot graphite has resulted in detection of the new species C12, C13, C14, and C15. A new carbon vapor source producing a beam 99% atomic carbon has been developed for vapor reflection experiments. Some initial experiments are described which reveal unexpected C3 desorption during flash vaporization of material condensed from the atomic beam on the graphite target.
