Vaporization Kinetics and Thermodynamics of Graphite Using the High Pressure Mass Spectrometer.
Abstract
The research concerns characterizing the nature and thermodynamics of species evaporating from graphite. Several equipment modifications are described which are designed to increase the time response of the bean-chopper reference signal. The major reseach effort was concerned with attempts to understand the rather puzzling and unexpected results obtained in time-of-flight velocity analysis of carbon vapor species. Ions from carbon vapor as well as several consensible gases, showed double humped time-of-arrival peaks. Ion source trapping in the Nuclide double-aperture ion source seems definitely to be involved, but simple trapping alone does not appear to account for the behavior of the C3(+) ion.
