Available in PDF, EPUB and Kindle. Book excerpt: A double mass-spectrometer system for the study of the dynamics of ion-neutral collisions at suprathermal energies is described in detail. The system consists of a Wien Filter, which acts as a source of mass-selected and velocity analyzed ions, coupled to a static-pressure collision chamber followed by a quadrupole mass filter, which acts as a mass analyzer for the products and the projectile ions. This apparatus has been used to measure ion-neutral collision cross sections and ion product times-of-flight. The methods utilized in the processing of raw experimental data are also described. The raw cross section data is corrected with respect to the collection efficiency, yielding integral cross sections which can be used in codes designed to predict the environment of spacecraft in low earth orbit. The performance of the experiment is demonstrated by measuring the known ion-neutral collision systems: N2(+) + Ar, N2(+) + D2, and O+ + H2O. Keywords: Ion neutral collisions; Mass spectrometry; Space effects. (JHD).

This book was released on 1990 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high temperature mass spectrometer used to obtain laboratory data on the thermochemical properties of materials encountered in space research is described in detail. The experimental procedures and data analysis necessary to obtain thermochemical constants from the mass spectrometer data are also described. The present experimental arrangement allows cell temperatures of up to 2100 K. Reliable measurements at signal levels below 10 ion counts/s can be made because of the very low background signal and the entirely automated data acquisition and averaging system. In preliminary studies of osmium and its oxides, it is shown that the choice of molybdenum as the cell material is detrimental. The use of an alumina Knudsen cell is proposed.
